Macro Compiling & Uploading

The controller uses 8, 16, 24, and 32-bit signed, unsigned, and floating point registers. There are two

types of register used in the controller.

Configuration Register

A configuration register stores signal constants that change only when they are reprogrammed. For

example, registers 1129 and 359 store digital counter channel 1 input scale and offset settings.

Working Register

A working register stores signal data that changes regularly due to variations in the input signal, as well

as the processes carried out by the

controller

's functions on the input signal. For example, register 645

stores the processed data for the input signal after it has been processed through the channel 1

functions programmed into the

controller

accommodate for Modbus usage of 32-point registers, only odd register addresses are used, providing

a maximum of 255 registers.

32-bit Pseudo Floating Point (1537 to 2047)

Modbus usage of 32-point registers, only odd register addresses are used, providing a maximum of

255 registers.

Pseudo floating point registers are basically floating point images of the 32 bit fixed point registers

ranging from register 257 to 767. The float value is created by dividing the original integer value in

accordance with it's decimal point selection (see

Display Format

). Not all 32 bit fixed point registers in

the above range have associated user selectable display format registers, and those that don't have

preset decimal point settings.

Note

: Pseudo floats are only available with

Display Format

settings from 000 to 006. Anything outside

of this range will produce incorrect results. Any rounding applied in the display format setting will be

ignored in the pseudo floating point value.

Hint

: If you add a register offset of 1280 to any valid 32 bit integer register in the range of 257 to 767, it

will address the associated pseudo floating point image of that register.

All registers in this range are single precision floating point numbers that conform to the IEEE-754

standard format. They can be read and written as standard floating point numbers, however they have

the following limitations.

Range and Truncation

Because these numbers are derived from an integer value, their range and resolution is limited by how

the integer value is configured. For example if the integer register has a display format setting of 1

decimal place, and the value of 0.001234 is written to the pseudo floating point register, the resulting

value written to the register will be 0.0.

If the same write is repeated when the display format is set to 6 decimal places then the resulting value

written to the register will be 1234 which will be displayed 0.001234.

If the above test is repeated with a display format setting of 4 decimal places, the resulting value

written to the register will be 12 which will be displayed 0.0012. The value is truncated and the last 2

decimal places will be lost.

Note

: Pseudo floating point registers 1537 to 2047 are only available in firmware version V0.08.01

onwards.

Zen IoT series controllers use

different types of memory to store register information. In some cases

the data is stored in RAM only and is lost at power down (i.e. volatile memory). In other cases the data

must be retained at power down so it must be saved in non volatile memory as well. There are also

some restrictions on the way some memory types can be used so that their endurance specifications

are not exceeded.

The table below shows the different memory types available in the

Zen IoT series controllers and the

memory characteristics and restrictions which may apply.

1.2 Memory Types

ZEN-IOT-REG-MAN-16V04

Introduction

Memory Type

Memory Characteristics

RAM

Random Access Memory. This memory is fast to access and is generally used for most working

variables. It is volatile memory and it contents are not saved after a power down. Generally this

memory is set to zero when the controller is turned on.

EEPROM

Electrically Erasable Programmable Read-Only Memory. This memory is slower to access and

usually has a write time of between 5 - 10mS. It also has a limitation of 1x10^6 write cycles which

must not be exceeded. There is no limit on the number of read cycles. EEPROM memory is non

volatile and it's contents are retained even with no power applied. The controller uses this memory

type for non volatile storage of data which is not accessed continuously by the operating system but

is needed from time to time.

RAM/EEPROM

This memory type is made up of a combination of the two memory types shown above (i.e. RAM and

EEPROM). It is probably the most common memory type used by the controller as it allows fast

access and also non volatile storage. When writing to this type of memory from the macro, the RAM

value is always updated and the EEPROM value is only updated if the

|NON_VOLATILE_WRITE

flags is set just prior to the write instruction. This allows the macro to continuously write to a register

without exceeding the maximum write cycle limit. When writing to this register via the serial port, both

the RAM and EEPROM are updated so care must be taken not to exceed the maximum number of

write cycles.

RAM/FLASH

his type of memory is similar to RAM/EEPROM in that it allows fast access and non volatile storage

but it uses FLASH memory for the non volatile storage instead of EEPROM. FLASH memory is

similar to EEPROM but is usually programmed in larger blocks of memory.

This type of memory is

used by the controller to store variables which are changing continuously and also need non volatile

storage. A write to one of these registers from the macro or the serial port only changes the RAM

value. This means that

there are no limitations on how many times the register is written. When the

power is removed from the controller it senses this and quickly copies the contents of these registers

into FLASH memory. When power is restored, the contents of the FLASH memory are copied back

into the RAM registers.

RAM/NVRAM

This type of memory uses RAM for fast access and non volatile RAM for data storage. The non

volatile RAM is a real time clock device which uses a small battery to retain the contents of the

memory during power down. The controller uses this type of memory to store time information.

RAMinputModule

Input modules have an on board microprocessor which contains registers in RAM that can be

accessed indirectly by via the index. (See note on

Input Module Registers (3073 to 4096)

)

FLASHinputModule

Input modules have a page of 512 bytes of onboard FLASH memory which holds calibration and

setup data. This memory has the similar features and restrictions as the EEPROM listed above.

Calibration and setup registers in the input module are written into RAM first via the index register

(8224) and then when all data is correct they can be saved to FLASH by setting the save bit (bit 0) in

the control byte. FLASH should only be saved in this way when absolutely necessary and care must

be taken not to exceed the maximum number of 10^5 write cycles. (See note on

Input Module Registers (3073 to 4096)

)

ASCII Mode

Modbus Mode

Character Frame Formats

Command Response Time

The ASCII mode is a simple communication protocol using the standard ASCII character set. This

mode provides external communication between the controller and a PC allowing remote programming

to be carried out. It was designed specifically so that it could be used with standard terminal emulation

software allowing the user to communicate with the controller without the need for specialized

software. Because of this fact it does not include any error checking or CRC bytes and is intended for

configuration of the controller over short distances.

1.3 Communication Formats

1.3.1 ASCII Mode

ZEN-IOT-REG-MAN-16V04

Zen Registers11

Zen IoT Series controllers use a serial communication channel to transfer data from the controller to

another device. With serial communications, data is sent one bit at a time over a single

communications line. The voltage is switched between a high and a low level at a predetermined

transmission speed (baud rate) using ASCII encoding. Each ASCII character is transmitted individually

as a byte of information (eight bits) with a variable idle period between characters. The idle period is

the time between the receiving device receiving the stop bit of the last byte sent and the start bit of the

next byte. The receiving device (for example a PC) reads the voltage levels at the same interval and

then translates the switched levels back to an ASCII character. The voltage levels depend on the

interface standard being used.

The following table lists the voltage level conventions used for RS-232 and RS-485. The voltage levels

listed are at the receiver.

Each ASCII character is

framed

with:

A start bit.

An optional error detection parity bit.

And one or more ending stop bits.

For communication to take place, the data format and baud rate (transmission speed) must match that

of the other equipment in the communication circuit. The following diagram shows the character frame

formats used by the controller.

Command Response Time

The Modbus mode uses the Modbus communication protocol to provide external communication

between a Zen IoT controller and a process device for monitoring, control, and automation purposes.

1.3.2 Modbus Mode

ZEN-IOT-REG-MAN-16V04

Introduction

Zen IoT controllers use Modbus RTU (Remote Terminal Unit) communication. This is an 8-bit binary

transmission mode. The main advantage of this mode is that its greater character density allows better

data throughput than ASCII for the same baud rate. Each message must be transmitted in a

continuous stream.

Zen IoT controllers can be configured as a Modbus slave device or a Modbus master. In the Modbus

slave mode, the controller acts as a slave to a Modbus master (PC or PLC). Data transfers are based

on registers and can only be initiated by the Modbus master. The Modbus master must be configured

to accept this type of data. Once this is done, seamless communication between the Modbus master

and Modbus slave can be initiated.

In Modbus master mode the controller initiates all communications to other Modbus slaves on the bus.

On Zen IoT controllers, the Modbus master mode must be used in conjunction with the

MODBUS_MASTER_MACRO which defines which slave devices are accessed.

(see

Modbus Master

In Modbus master mode, Zen IoT Series controllers can only access Modbus Holding registers (in the

Modbus 40000 address range) and Input registers (in the Modbus 30000 address range) in external

Modbus devices. Coils (20000) are not currently supported.

Modbus Command Summary

All of the registers currently incorporated in Zen IoT Series controllers are accessed as "Holding

Registers". Although strictly speaking this means that all of the registers are read/write registers, there

are some exceptions to this rule. However the majority of these registers are read/write registers.

There are no Discrete input registers, Coils or Input registers available in the Zen IoT.

Addressing Convention

All registers numbers contained in this document refer to the original Modbus convention for

addressing where register 1 is addressed as 0x0000 in the data packet.

For example, the register number for the Channel 1 processed data register is shown in this document

ZEN-IOT-REG-MAN-16V04

Zen Registers13

as 9. In Modbus terms this is referred to as 40009. However the actual or direct address contained in

the Modbus data packet would be 0x0008 (i.e. 1 count less).

Data Orientation

Zen IoT controllers contain a combination of 8 bit, 16 bit, 24 bit, 32 bit integer, 32 bit floating point

registers. The original Modbus protocol only allows for 16bit data registers so to access larger

registers, multiple 16 bit registers are accessed. You will notice that all 24 and 32 bit register numbers

in the Zen IoT are odd addresses only so that they are spaced 2 register addresses apart from each

other. This allows block reads of 32 bit registers to be carried out while still maintaining the correct

In Zen IoT controllers the data for 24 and 32 bit registers is transmitted LSW (Least Significant Word)

first followed by the MSW (Most Significant Word). In Modbus master mode the user can specify the

MB_SWAPPED option to access slave devices which use the alternate format. (See

Modbus Master

)

For example;

If register 40009 points to a 32 bit long which contains the value 12345678 (0xBC614E hex) then

1st pair of 8 bit bytes transmitted = 0x61 0x4E

2nd pair of 8 bit bytes transmitted = 0x00 0xBC

If the internal register is a 32 bit floating point number then the 1st two 8 bit values transmitted are the

least significant 16 bits of the mantissa, while the next two 8 bit values transmitted give the sign, 8 bits

of exponent and the most significant 7 bits of the mantissa.

For example;

If register pair 41025 points to a 32 bit float which contains the value –12.5 (0xC1480000 hex) then

1st pair of 8 bit bytes transmitted = 0x00 0x00

2nd pair of 8 bit bytes transmitted = 0XC1 0x48

8 bit Registers

In cases where the internal register is only an 8 bit value, the MSB will be set to zero (if the register is

an 8 bit unsigned value) or to the sign (if the register is an 8 bit signed value).

Text String Registers

Zen IoT controllers also contain various text string registers. Text strings vary in maximum length and

all text strings must be terminated with an ASCII null (0x00). Most text strings are 14 chars+null (so 15

chars in total) but some are 30chars+null and some are also 62chars+null. (See specific info on each

A string can be shorter than the maximum length provided that unused characters are padded with

ASCII nulls.

Each character in the string is sent in the same order as it appears in the original text

string (i.e. 2 characters per 16bit word).

Our addressing of text registers does not strictly adhere to the Modbus spec in that the register number

specified for each text string is only used as an entry point into the text string. So for example, register

4016393 is the register number used to access the channel name for input channel 1 which can be up

to 14 ASCII characters in length plus a null (ASCII 0x00) terminating character. So the Modbus frame

required to read this would be as follows:

Add Funct Start Add Hi Start Add Lo No. of regs Hi No. of regs Lo Chksum

??? 0x03 0x40 0x08 0x00 0x08 ???

If the channel name was set to "Temp_1" the reply would be as follows:

Add Funct Byte Count Byte1 Byte2 Byte3 Byte4 Byte4 Byte5 Byte6 .......

Byte16 Chksum

??? 0x03 0x10 0x54(T) 0x65(e) 0x6D(m) 0x70(p) 0x5F(_) 0x31(1) 0x00

0x00 ???

Under standard Modbus addressing another read of register number 4016395 would access byte 5

ZEN-IOT-REG-MAN-16V04

Introduction

and 6 (i.e. "_1") of the channel 1 name, but this is not the case in our implementation. Instead register

number 4016395 addresses the start of the next text string (i.e. then channel name for input channel

2).

The only limitation with the way we address text string registers is that you can only read/write one

complete text string in a single Modbus frame. You cannot access consecutive text string registers in a

single long Modbus block read/write. Reading past the maximum size a text string register will give

random result values for the unused characters so we recommend that you limit your read/write

lengths to those specified for each register.

Data packet Size

Zen IoT controllers can transmit and receive Modbus data packets up to 255 bytes in length.

Modbus/TCP Slave Option

Zen IoT controllers can be supplied with an Ethernet option fitted to serial port 1. When the Ethernet

option is fitted, the Zen IoT will automatically switch to Modbus/TCP mode when the Modbus RTU

slave protocol is selected for serial port 1. (This also applies to the Intech/Modbus RTU slave protocol.

See

Intech Mode

.) With the Ethernet option fitted the internal serial rate is fixed to 230400 baud, no

parity. The Ethernet adapter (Xport device) must be configured with its serial channel set to match.

(See

ICC402 Ethernet

for more information on how to setup the Ethernet port).

NOTE:

Later versions of Zen IoT firmware include a Modbus/TCP wrap option which wraps/unwraps

TCP packets around a serial frame of data. Its intended for use with some cellular modems and this

mode should not be used for standard Modbus/TCP communications.

Modbus RTU In Intech Mode

The Intech communications mode also allows Modbus RTU messages to be handled without switching

to the standard Modbus mode. In Intech mode, Modbus RTU timing restrictions are slightly relaxed

from the Modbus standard with only the inter frame timeout being checked during receive.

Firmware V2.2.01 onwards include an MQTT V3.3.1 client operating on port 1. Port 1 can be fitted with

a RS232/485 interface, an Ethernet interface or a WiFi module.

The MQTT client must be used in conjunction with a macro or a plugin and cannot operate without this.

Start Bit and Data Bits

Data transmission always begins with the start bit. The start bit signals the receiving device to prepare

to receive data. One bit period later, the least significant bit of the ASCII encoded character is

transmitted, followed by the remaining data bits. The receiving device then reads each bit position as

they are transmitted and, since the sending and receiving devices operate at the same transmission

Zen Registers15

speed (baud rate), the data is read without timing errors.

Parity Bit

To prevent errors in communication, the sum of data bits in each character (byte) must be the same:

either an odd amount or an even amount. The parity bit is used to maintain this similarity for all

characters throughout the transmission. It is necessary for the parity protocol of the sending and

receiving devices to be set before transmission. There are three options for the parity bit, it can be set

to either:

None – there is no parity.

Odd – the sum of bits in each byte is odd.

Even – the sum of bits in each byte is even.

After the start and data bits of the byte have been sent, the parity bit is sent. The transmitter sets the

parity bit to 1 or 0 making the sum of the bits of the first character odd or even, depending on the parity

protocol set for the sending and receiving devices.

As each subsequent character in the transmission is sent, the transmitter sets the parity bit to a 1 or a

0 so that the protocol of each character is the same as the first character: odd or even.

The parity bit is used by the receiver to detect errors that may occur to an odd number of bits in the

transmission. However, a single parity bit cannot detect errors that may occur to an even number of

bits. Given this limitation, the parity bit is often ignored by the receiving device. You set the parity bit of

incoming data and also set the parity bit of outgoing data to odd, even, or none (mark parity).

Stop Bit

The stop bit is the last character to be transmitted. The stop bit provides a single bit period pause to

allow the receiver to prepare to re-synchronize to the start of a new transmission (start bit of next byte).

The receiver then continuously looks for the occurrence of the start bit.

Command Response Time

The controller uses half-duplex operation to send and receive data. This means that it can only send or

receive data at any given time. It cannot do both simultaneously. The controller ignores commands

while transmitting data, using RXD as a busy signal.

When the controller receives commands and data, after the first command string has been received,

timing restrictions are imposed on subsequent commands. This allows enough time for the controller to

process the command and prepare for the next command.

See the Timing Diagram below

. At the start of the time interval

, the sending device (PC) prints or

writes the string to the serial port, initiating a transmission. During

the command characters are

under transmission and at the end of this period the controller receives the command terminating

character. The time duration of time interval

depends on the number of characters and baud rate of

the channel:

t1 = (10 * # of characters) / baud rate

At the start of time interval

, the controller starts to interpret the command, and when complete

performs the command function.

After receiving a valid command string, the controller always indicates to the sending device when it is

ready to accept a new command. After a read command, the controller responds with the requested

data followed by a carriage return (øDH) and a line feed (øAH) character. After receiving a write

command, the controller executes the write command and then responds with a carriage return/line

feed.

The sending device should wait for the carriage return/line feed characters before sending the next

command to the controller.

1.3.6 Command Response Time

ZEN-IOT-REG-MAN-16V04

Introduction

If the controller is to reply with data, time interval

is controlled by using the command terminating

character:

or *. The

terminating character results in a response time window of 50 milliseconds

minimum and 100 milliseconds maximum. This allows enough time to release the sending driver on

the RS-485 bus. Terminating the command line with the

symbol, results in a response time window

(t2) of 2 milliseconds minimum and 50 milliseconds maximum. The faster response time of this

terminating character requires that sending drivers release within 2 milliseconds after the terminating

character is received.

At the start of time interval

, the controller responds with the first character of the reply. As with

t1,the time duration of

depends on the number of characters and baud rate of the channel:

t3 = (10 * # of characters) / baud rate

At the end of

the controller is ready to receive the next command.

The maximum throughput of the controller is limited to the sum of the times:

t1, t2, t3.Timing Diagram

Command String Construction

When sending commands to the controller using a Terminal emulation program, a string containing at

least one command character must be constructed. A command string consists of the following

characters and must be constructed in the order shown:

Command String Construction Diagram

Start Character

Use S or s for the start character of a command string. This must be the first character in the string.

Controller Address

Use an ASCII number from

255

for the controller address. If the character following the

start

character is not an ASCII number, then address

is assumed. All controllers respond to address

0.Read / Write Command

1.4 ASCII Mode Format

ZEN-IOT-REG-MAN-16V04

Zen Registers17

The next character must be an ASCII

or r for read, an ASCII

or u for an unformatted read, or an

ASCII

or w for write. Any other character aborts the operation.

The register address for the read/write operation is specified next. It can be an ASCII number from

65535

or, for special text registers, an ASCII letter from

to Z which is not case sensitive. If the

address character is omitted in a read command, the controller always responds with the data value

currently on the display. The register address must be specified for a write command.

Separator Character

After the register address in a write command, the next character must be something other than an

ASCII number. This is used to separate the register address from the data value. It can be a

space

ora ,

(comma), or any other character except a

(dollar) or an

(asterisk).

Data Value

After the separator character, the data value is sent. It must be an ASCII number in the range of

32766

Message Terminator

The last character in the message is the message terminator and this must be either a

(dollar) or an

(asterisk).

If the

is used as a terminator, a minimum delay of 50 milliseconds is inserted before a reply is sent.

If the

is used as a terminator, a minimum delay of 2 milliseconds is inserted before a reply is sent.

NOTE

: The

and the

characters must not appear anywhere else in the message string.

Controller Response

After the controller has completed a read or write instruction it responds by sending a carriage

return/line feed (CR/LF) back to the host. If the instruction was a read command, the CR/LF follows the

last character in the ASCII string. If it was a write command, a CR/LF is the only response sent back to

the host. The host must wait for this before sending any further commands to the controller.

Unformatted Read

In the ASCII mode data is normally read as formatted data which includes decimal point and any text

characters that may be selected to show display units. However it is also possible to read unformatted

data (i.e. no decimal point and no text characters) by using a "

" or "

" in the read command instead of

an "R" or "

". The following command sequence would be used to read unformatted data in channel 4

from controller address 3.

S3U15*

NOTE:

There is no unformatted write command. When writing to fixed point registers, any decimal

point and text characters are ignored.

Multiple Write

ASCII Text Registers

This feature allows multiple registers to be written in a single ASCII command string. It is similar to a

normal write command with the following differences:

After the first data value, a separator character is inserted instead of the message terminator. Then

the next register address is specified, followed by another separator character and the next data

value. This procedure is repeated for each new register. The message terminator is added after the

last data value in the string.

Any number of registers can be written in the above manner provided the total length of the

command string does not exceed 73 ASCII characters, including spaces and message terminator.

The registers described in the topics of this Help are available for controller configuration and macro

programming purposes. Each register is identified in four ways, by:

Name

This is the name of the register and relates to its function.

Description

This describes the function of each register.

Symbol Type

Under Symbol Type, the following abbreviations identify the register type:

The symbol B_ is followed by a number from 0 up to 31 and describes the

F_32

The symbol F_32 identifies the register as a floating point 32-bit register

(IEEE-754). (Modbus word order is Little Endian)

PF_32

The symbol PF_32 identifies the register as a pseudo floating point 32-bit

32-

bit Pseudo Floating Point (1537 to 2047)

SF_32

The symbol SF_32 identifies the register as a swapped floating point 32-bit

This register type was included to maintain backwards compatibility with older

Intech products.

The symbol _R identifies the register as a read only register and may be

attached to another symbol. For example, B_0_R identifies this as bit 0 read

only.

The symbol S_ is followed by either 16, 24, or 32, identifying the register as a

16, 24, or 32-bit signed integer.

The symbol U_ is followed by either 8, 16, or 32 identifying the register as an

8, 16, or 32-bit unsigned integer.

The symbol O_ is followed by either 8, 16, or 32 identifying the register as an

8, 16, or 32-bit unsigned integer which is displayed in an octal format.

The symbol _W identifies the register as a write only register.

The symbol _L identifies the register as a text string that contains printable

ASCII characters from 0x20 - 0x7a.

This is the number that identifies the register in the controller.

Memory Types

The Zen IoT Series controller incorporates a number of text registers for storage of ASCII text strings.

These strings vary in length from 8 to 62 characters depending on the intended function of the text

text data.

Text registers can be accessed in the ASCII serial mode via the serial port or from the Macro.

Print String - Register 16543

When setup in the print mode, the controller can print data from any register directly to a serial printer,

or to a PC where it can be imported into a spreadsheet.

registers to be printed out when a print command is issued by the controller while in the print mode.

Through the serial port, register 16543 can be either written to or read from using a terminal program

on a PC.

Writing To Register 16543

Writing to register 16543 tells the controller to print the data stored in one or more of the controller's

registers when the print command is issued. To get the controller to print, the printer must be

connected to the controller through the serial port and the controller must be programmed to run in the

2.1.1 Print String - Register 16543

ZEN-IOT-REG-MAN-16V04

Zen Registers25

print mode

. The data to be printed depends on how the controller has been programmed.

For example, to display a flow rate and total. The total length of a write string can be up to 62 ASCII

characters long. See Printing Restrictions.

Reading From Register 16543

Reading from register 16543 allows you to check your settings prior to removing the PC from the serial

port and connecting to a printer. Register 16543 can be read in the normal manner: SR16543$.

Example of Writing To Register 16543

The following example shows a write to register 16543 with the controller setup to display flow rate and

total flow of channel 1.

swx Rate = ~1

(add carriage return and line feed)

Total = ~37$

The above write to register 16543 means the following:

sw16543

Start writing to register 16543.

Rate =

Tells the controller to print the word Rate =.

~1:Tells the controller to print the current flow rate (display data), held in register

1, after the word Rate =.

Total =

Tells the controller to print the word Total =.

~37:Tells the controller to print the current total flow (stored data), held in register

37, after the word Flow =.

The printer would then print, for example, the following:

Rate = 2000

Total = 25000

This means that the current flow rate is 2000 and the total flow at this point is 25000.

Example of Reading From Register 16543

Having written the above example to the controller, to check the contents of register 16543 using the

terminal program through the PC, type the following:

sr16543$

The following is shown on the PC screen:

Rate = ~1

Total = ~37$

Printing Restrictions

When printing, any alphanumeric ASCII character can be used within the following restrictions:

The

and

characters are reserved for the terminating character at the end of the string and cannot

be used as part of the text string.

The total string length must be no greater than 62 bytes long. This includes spaces, tabs, carriage

returns, line feeds, and the terminating character. There must be a separator space between the

Note, this separator space does not have to be

included in text string length calculations

.·Any number following a

(tilde) character is interpreted as a register address. During a printout the

The ASCII character

is treated as a special character in the print string. When a

is encountered, a

is printed in its place (

is reserved as a terminating character and normally can not appear

anywhere in the text string). This allows the print output of one controller to be connected to another

controller that is operating in the ASCII mode.

ZEN-IOT-REG-MAN-16V04

For example, if the print string reads:

swx sw3 ~11\ sw4 ~13\ sw6 ~1\$

The printer prints the following:

sw3

(current register value)

* sw4

(current register value)

sw6

(current register value)

Up to seven different registers can be specified in one text string, provided that the total string length is

no greater than 62 bytes long and the total length of the resulting printout is less than 100 bytes long

(including time stamp if selected).

For example, the following tab delimited output could be specified to input display data, processed

result, processed channel 1, processed channel 2, peak, valley, and total, directly into a spreadsheet:

swx ~1(tab)~7(tab)~9(tab)~11(tab)~57(tab)~59(tab)~37$

When calculating the length of the printout, an allowance of 7 bytes for each register address should

be used, plus any extra text or separating characters such as tabs or spaces.

NOTE

: As a new line is usually represented by a carriage return and a line feed, 2 bytes should be

added for each new line in text string length calculations.

The

Zen IoT

controller can have up to 16 analog input modules fitted. These can be configured for a

variety of different input sensors including RTD temperature probes, thermocouple temperature

probes, voltage and current measurement and counters. Input modules can be isolated or non-isolated

types. Each type of input module will have different setup and configuration requirements which need

to be adhered to for correct functionality.

However, regardless of which type of input module is fitted, the

Zen IoT

main controller will poll all input

modules and create an updated copy of the result and status registers of each input module. This data

is then scaled and becomes available in the analog result registers shown in this section.

This section also shows the various configuration registers associated with the result data.

NOTE: The configuration of each input module must be done separately via the index register 8224.

Channel 16

The Zen IoT controller can be configured to have all of its 16 analogue input channels to work with

thermocouple temperature probes. In this mode, cold junction temperature compensation is carried out

by measuring the ambient temperature inside the Zen IoT controller at the input terminals.

However in some applications it is desirable to measure the cold junction temperature at an external

source. To allow for this the Zen IoT has two cold junction select registers which allow the user to

define an input channel to be used as a cold junction temperature reference.

There are two registers associated with this function;

: The input channel selected to measure the cold junction temperature must be set to operate in

RTD input mode

with a resolution of

0.1 degree F

. Even if the final temperature results for the other

TC channels are set to read in degrees C with a different resolution, the cold junction channel must be

set as above.

The function of these registers is shown in the table below.

Cold junction temperature is taken from input channel 13 result.

Cold junction temperature is taken from input channel 14 result.

Cold junction temperature is taken from input channel 15 result.

Cold junction temperature is taken from input channel 16 result.

Note

: It is possible for both CJC_SELECT_LOW and CJC_SELECT_HIGH to select the same input

channel. This allows 15 thermocouples to be used with only 1 cold junction RTD channel.

The following registers are used to hold time and date information from the real-time clock. These

read/write registers are continuously updated by the operating system of the controller. If the real-time

clock option is installed in the controller, then these registers are maintained even during power down.

If the real-time clock option is not installed in the controller then these registers are still updated by the

controller, but all values are lost when the power is removed from the controller.

Zen IoT controllers support daylight saving correction and

Time Zone

The daylight saving function works by detecting the start and end of daylight saving time as per the

configuration specified by the user. If it detects that the current time stamp lies outside of the selected

daylight saving period, it reports the current time at the selected

time zone

. If it finds that the current

time stamp lies within the daylight saving period, it then adds the users predefined time offset to the

time and also updates a

current time zone

Note 1:

In order for daylight saving to work correctly it is important that all

clock

parameters are

correctly synchronized for your local time and your current

time zone

. This also includes the day of the

week. If any

clock

parameters are not correct, daylight saving adjustments will be incorrect.

Note 2:

DS_START_MONTH and DS_END_MONTH must be different. Setting DS_START_MONTH

and DS_END_MONTH to the same value will disable the daylight saving function.

Configuration Registers

Registers 8193 to 8200 are 8-bit registers used to control the functionality of the controller. When

reading or writing to these registers via the serial port in ASCII mode, the data is treated in octal

format. The function selected in the 1st digit of each register is stored in bits 6 and 7. The function

selected in the 2nd digit of each register is stored in bits 3, 4, and 5. The function selected in the 3rd

digit of each register is stored in bits 0, 1, and 2.

For example

If the manual setup for COUNTER_A_SETUP shows 241 on the display, then reading register 8197 in

ASCII mode results in a value of 241. Converting this octal value to a binary equivalent of 10100001 or

1XX = 50hz supply rejection.

2XX = Reserved for future development

3XX = Reserved for future development

2nd Digit - Analogue Output Mode

The 2nd digit of the analog mode setup register (bits 3, 4, 5) selects different analogue output modes

as per the following options:

X0X = Intech 2100M driver mode.

X1X = Normal mode (SCADA).

3rd Digit - Analogue Output Options

The 3rd digit of the analog mode setup register (bits 0,1, 2) has different options depending on the

selection of the second digit. The various options are shown below for each relevant setting of the

second digit.

2nd digit = 0

If the 2nd digit of the analog mode setup register is set to 0 (2100M driver mode) then the 3rd digit

functions as shown below;

X00 = 700mS delay between clock pulses.

2.4.1 Analogue Mode Setup

X04 = 4 seconds delay between clock pulses.

X05 = 5 seconds delay between clock pulses.

X06 = 6 seconds delay between clock pulses.

X07 = 7 seconds delay between clock pulses.

2nd digit = 2

If the 2nd digit of the analog mode setup register is set to 2 (PLC RTX (clk/rst) mode) then the 3rd digit

functions as a debounce timer for the clock input pin (D2) with the following options;

X20 = No debounce time.

X21 = 2.5mS debounce time.

X22 = 5mS debounce time.

X23 = 10mS debounce time.

X25 = 50mS debounce time.

X26 = 100mS debounce time.

X27 = 200mS debounce time.

2nd digit = 3

If the 2nd digit of the analog mode setup register is set to 3 (PLC RTX (BCD) mode) then the 3rd digit

gives the following options;

X30 = 12 bit result values output on analogue O/P 1, 12 bit scaled setpoints output on analogue

O/P 2. (Intech compatibility mode).

X31 = 32 bit result values output on analogue O/P 1, 32 bit totals 1-10 output on analogue O/P 2.

X33 = Reserved for future development.

X34 = Reserved for future development.

X35 = Reserved for future development.

X36 = Reserved for future development.

X37 = Reserved for future development.

Note: If the analogue mode is set to X31, BCD input values of 0-9 will cause TOTAL1 - TOTAL10

values to be output on analogue output 2. For BCD input values 10 - 15, analogue output channel 2 will

operate in normal mode and output whatever register the

DATA_SOURCE_ANALOG2 points to.

2nd digit = 1 or 4-7

If the 2nd digit of the analog mode setup register is set to 1, or 3 to 7 then the 3rd digit has no function.

It is recommended that the 3rd digit be set to 0.

NOTE: Some analogue output mode settings shown above also require the use of various

digital input pins. Setting the analogue output to these modes will over ride other settings for

Data Logging

Data Logging Concepts

The

Zen IoT

controller includes 4 digital input pins. These can be configured for a variety of different

input functions including standard digital status inputs, various counter modes and frequency counter

modes.

The 4 digital input pins

are not isolated from the

Zen IoT

power supply

so care must be taken when

connecting these inputs to sensors etc. All 4 inputs share the same common pin. The maximum

frequency of these input pins is limited to approximately 10kHz (or pulse widths > 50uS) and they

accept an input voltage range of 2-30V DC with a typical threshold value of 1.2V.

Each of the 4 digital channels has a number of associated registers which hold result and setup data.

The result registers are normally updated by the operating system of the controller after each new input

sample is processed.

The result registers can be read or written to, however the outcome of a write

operation to a result register will vary depending on the operational mode of the counter. The following

outcomes are possible.

Digital Input Mode

If the counter channel is placed in the digital input only mode (see

Counter Mode Setup

and

Analog Mode Setup

) the COUNTER_x register will show a value of "1" or "0" to reflect the current input

status of the digital input pin (

Note: this only applies to firmware versions 0.09.03 onwards

). The result

registers COUNTER_x_SCALED, COUNTER_x_RAW and COUNTER_x_16 are totally separate from

each other and they are not updated by the operating system. They can be used as storage registers

by the serial port or the macro.

Gated Interval Logging

Firmware V0.09.04 onwards includes a gated interval logging option. When this option is selected for

one of the digital status input pins, normal data logging will be disabled when the digital input is in-

active. Data will only be logged at the rate specified by the LOG_INTERVAL_TIME when the digital

input is active (i.e. "ON"). If 2 or more of the digital status inputs are setup in this mode then they form

an "AND" function and normal data logging will be activated when all selected inputs are active. The

leading edge of a pulse will also be logged with the trigger type for the digital input.

Counter Input Mode

If the counter channel is placed in the counter mode (i.e. up counter or up/down counter) then input

counts are applied to the COUNTERx_RAW register, which is then scaled and applied to the

COUNTER_x_SCALED register. If 32 point linearization is enabled then the COUNTER_x_SCALED

value is taken as an input value and the linearized output value is applied to COUNTER_x. If 32 point

linearization is disabled, the COUNTER_x_SCALED value will be copied into the COUNTER_x register

directly. So these registers are updated by the operating system after each new input sample.

However, a write to these registers is still possible in counter mode to enable the setting or resetting of

the count value.

The COUNTER_x_16 register is effectively a copy of the COUNTER_x_RAW register, and is provided

to maintain compatibility which older products.

Note

: Because COUNTER_x_16 is only a 16 bit register, it will only show the lowest 16 bits of the

COUNTER_x_RAW register. For example, if COUNTER_x_RAW equals 65536 counts then

COUNTER_x_16 will show a value of 0.

2.5 Counters

ZEN-IOT-REG-MAN-16V04

A write to the COUNTER_x_RAW register will effect the COUNTER_x_SCALED, COUNTER_x and

COUNTER_x_16 registers. The COUNTER_x register will be updated in accordance with the scale

and offset values applied to the counter channel, and any linearization settings. The COUNTER_x_16

A write to the COUNTER_x_SCALED register will update the COUNTER_x_RAW register in

accordance with the scale and offset values applied to the counter channel. This inturn will cause the

COUNTER_x_16 and COUNTER_x registers to be updated with a new value as well. Note:if the value

written to COUNTER_x_SCALED causes the COUNTER_x_RAW value to be greater than 65535,

then COUNTER_x_16 will only show the lowest 16 bits of COUNTER_x_RAW.

A write to the COUNTERx_16 register will also update the COUNTERx_RAW register with the same

value. COUNTERx_SCALED and COUNTERx registers will also be updated on the next sample

accordance with the scale and offset values and any linearization applied to the counter channel. .

Frequency Counter Input Mode

If the counter channel is placed in the frequency counter mode then the frequency in Hz is applied to

the COUNTER_x_RAW register, which is then scaled and applied to the COUNTER_x_SCALED

value and the linearized output value is applied to COUNTER_x. If 32 point linearization is disabled, the

COUNTER_x_SCALED value will be copied into the COUNTER_x register directly. So these registers

are updated by the operating system after each new input sample. Any writes to these register will be

lost because the operating system is continuously over writing them with new input samples.

Note

: In frequency counter mode COUNTER_x_16 registers are hold a 16 bit copy of

COUNTER_x_RAW register. If COUNTER_x_RAW > 65535 then COUNTER_x_16 will display 65535.

This is different to straight counter mode - see

Counters

Most registers from register #1 to register #32765 can be logged. Registers are logged according to

what type of register they are, with floating point and text registers also able to be logged. The Zen IoT

controllers can log up to 32 different channels in each sample (depending on the data type/size of each

channel being logged).

31,774 samples (data records) can be stored (logged) in internal non-volatile memory for before and

after analysis of any process condition.

Note: Some models of Zen IoT controllers do come with RTC and data FLASH memory installed. The

Zen IoT controller

must have

RTC/data FLASH memory installed for data logging to function.

Data logging can be triggered (activated) from the logging timer, a setpoint, a front panel button, an

external switch, via the serial port or from a macro command. With a real-time clock installed, date and

time stamps can be included.

2.6.1 Data Logging Concepts

The data logging function uses the concept of pointers to control where a sample is to be written to and

from where one is to be read. These pointers are referred to as the log write pointer and the log read

pointer.

Log Write Pointer

counts up from 0 each time a new sample is logged, with the maximum number of samples being

limited by the size of non-volatile memory installed in the controller and also the number/size of

registers to be logged. Before a new sample is written, the controller first checks to make sure that it is

not overwriting a sample that has not been read. It does this by comparing the write pointer with the

read pointer. If they are the same and the

Linear

logging mode has been selected, data logging is

halted until a read is actioned. If this occurs, new samples are lost. If the

Cyclic

mode has been

selected, the oldest sample will be overwritten with new data and the old sample will be lost. When the

sample number reaches the maximum count it wraps around to 1.

the allowable range for the size of the installed memory.

Log Read Pointer

counts up from 0 each time log data is read from the controller, with the maximum number of samples

being limited by the size of non-volatile memory installed in the controller and also the number/size of

registers to be logged. When it reaches the maximum count it wraps around to 1. When it reaches the

write pointer the log buffer is empty and no more data can be read out of the log.

the allowable range for the size of the installed memory.

Note

: Although the log read and write pointers can be reset to zero, sample zero is never used to hold

any real sample data. It is only used as "resting point" when the pointers are cleared. This is because

the pointers are always pre-incremented before the sample is written. When pointers wrap around at

the end of memory they wrap around to the value of 1.

Log Reverse Read Pointer

the reverse read register 16549. It is decremented

after

each read from 16549 and works its way down

until it reaches the current value of the read pointer. When it reaches the read pointer it stops and no

further log samples are sent out. Unlike registers 489 and 491, this register resides in volatile RAM

only and must be setup prior to a block read operation. When it reaches the minimum count of 1 it

wraps around to the maximum sample number.

the allowable range for the size of the installed memory.

Buffer Types

The controller has two types of buffer.

Cyclic Buffer

. With the

cyclic

buffer selected in the Meter Configuration Utility program, the log write

pointer (register 489) increments each time a sample is taken. When it exceeds the maximum sample

number (determined by the amount of non-volatile memory installed and the number/size of registers

to be logged) it wraps around to zero. If the write pointer equals the read pointer then oldest (unread)

data will be overwritten with the new data and old data will lost. This means that when the cyclic buffer

is full, the logged data is replaced on a first ON first OFF basis. This means that when the buffer is full,

the first logged sample is discarded to make way for a new sample at the end of the logged data string.

It then wraps around to sample number 1 again.

See description on

Log Read Pointer

for information about not overwriting old samples that have not

been read.

Linear Buffer

. With the

linear

buffer selected in the Meter Configuration Utility program, the log write

ZEN-IOT-REG-MAN-16V04

Zen Registers73

pointer increments each time a sample is taken until it reaches the read pointer. When it equals the

read pointer the controller stops logging data and any new data is lost. If the sample number reaches

the maximum sample number (determined by the amount of non-volatile memory installed and the

number/size of registers to be logged) it will wrap around to zero. When the linear buffer is full it must

either be read or reset to 0. See

Reset Buffer

With

reset buffer number to 0

set in the Meter Configuration Utility program, the log write and log

read pointers are reset to zero when the PROGRAM button is pressed. The controller then reverts

back to the same setting it had before the reset function was executed (either cyclic or linear). Note

that when the reset function is executed, the contents of the buffer is not destroyed, only the pointers

are changed.

Note:

The reset buffer function only works from a display panel. To reset pointers via the serial port

they should just be written to individually.

Registers 4275 to 4306

Registers 4275 to 4306 can be read from and written to as normal registers. Registers 4275 to 4306

can only be configured via the serial port or from the macro and are not accessible from the front panel

buttons.

Registers 4275 to 4306 are used to specify which registers are to be logged. Register 4275 specifies

the first register to be logged, 4276 the second, 4277 the third, and so on. Writing a value of zero to

one of these registers disables the register from taking any logs.

Up to 32 registers in total can be logged in each sample

however the actual number depends on the

size of each register being logged

. The overall size of each stored sample is 132 bytes and each

sample has a fixed overhead of 8 bytes as shown below.

Each sample will always include:

1 byte required for trigger source.

3 bytes required for date stamp.

3 bytes required for time stamp.

1 byte required for checksum (last byte in sample).

This means that all the logged channels must fit into the remaining 124 bytes. The data in each sample

can be made of a combination of any of the following data types:

8-bit registers use:

1 byte

16-bit registers use:

2 bytes

24-bit registers use:

3 bytes

32-bit registers use:

4 bytes

Text registers:

Number of bytes depends on length of text string.

(Custom Text strings can be stored but only with special macro command "log_message" or via a

serial port write to register 16553. See

Read Single Log Data at Log Read Pointer - Register 16553

)

Non-volatile Memory Options

When the controller is fitted with the internal data logging memory option, then 32Mbit of non-volatile

on-board memory (data FLASH) is installed. This allows up to 31,774 samples to be logged.

NOTE: Altering registers 4275 to 4306 will potentially effect the order of the data within a

sample and may also render any previously stored log data as unreadable. All current log data

should be read and saved before changes are made to these registers and they should be

correctly configured before any new samples are taken.

Special Log Functions

Most data log samples are trigger by the log timer, a setpoint or from an input pin but log samples can

also be triggered from other sources such as special macro commands or from the serial port. There

are 2 special macro commands which allow log samples to be triggered as shown below.

"force_log" command - This macro command triggers a log sample to be taken in the standard format.

ZEN-IOT-REG-MAN-16V04

The sample is taken the instant the command is executed.

"log_message" command - This macro command allows a text string to be logged by the data logger. It

requires a following text string enclosed in quotation marks (") and allows the logging of custom

messages from the macro. The maximum length of the text string is governed by the data logging

settings for registers 4275 - 4306.

There are also 2 ways of triggering a data log from the serial port as shown below.

Write to register 8442 - a write to register 8442 via the serial port will trigger a log sample to be taken in

the standard format. It allows log samples to be triggered from another serial device.

Write to register 16553 - a write to register 16553 via the serial port allows a text string to be logged in

a similar manner to the "log_message" macro command. In this case the text string to be logged is

included in the serial command in a similar manner to writing to other text registers.

2.6.2 Read Only Registers

These read only registers are provided to allow the user to selectively read a single parameter from a

log sample, instead of reading all parameters in a sample. Only numeric parameters can be read (not

text) and they will always be drawn from the sample which the log read pointer is currently pointing to.

The user must ensure that the log read pointer is pointing to the correct sample of number before

reading these registers. On previous firmware versions (earlier than 4.04.01), reading any of these

registers does not alter the log read pointer position. On the Zen IoT an auto increment feature has

been added.

the maximum number of samples being limited by the current memory size installed in the controller

and the setting of registers 4275 to 4306. When it reaches the maximum count it wraps around to 1.

Registers 493 to 523 and 545 to 575 provide numeric values for the 1

through to the 32

logged in accordance with registers

4275 to 4306

. The size and type varies depending on the size and

data type of the registers addressed by registers 4275 to 4306. These registers give an unformatted

numeric value that can be read in ASCII or any other serial mode.

The user should ensure that the log read pointer is set to the required sample number before

accessing any of these registers.

If the sample does not contain the data that is requested, the controller responds by sending a null

character in ASCII mode, or a data error in Modbus mode.

Registers 4275 to 4306 are used to specify which registers the data logger logs. Register 4275

specifies the first register to be logged, 4276 the second, 4277 the third and so on. Setting one of these

registers to zero disables that register from logging any data. Changing registers 4275 to 4306

potentially changes the

format and order of data within a sample and may also render any previously

stored log data as unreadable. All current log data should be read and saved before changes are made

to these registers and they should be correctly configured before any new samples are taken.

Registers 4275 to 4306 can be read from and written to as normal registers. Most of the registers in

the controller can be logged. This includes floating point and text registers.

: Text registers 16553, 16555 and 16543 should not be logged.

2.6.9 Read Log Sample Data

Registers 8443 to 8450 are read only registers used to access data from a log sample. A read of one

of these registers reads the appropriate data from the log sample which is addressed by the current

value of the log read pointer (register 491). The user must setup the log read pointer to the required

sample number before accessing registers 8443 to 8450.

In each case the output is a numeric value only. Registers 8443 to 8450 can be read in ASCII or

Modbus modes and can also be read from the macro.

NOTE

: The information in registers 8443 to 8450 is logged in every sample, regardless of the settings

in the Meter Configuration Utility program.

This register provides an 8-bit numeric value that defines the trigger point for the sample.

pointer (register 491) with the log write pointer (register 489). If they are equal then there has been no

new samples logged since the last read and the message

No New Log Data

is sent as a response. If

they are not equal, the log read pointer (register 491) is incremented to point to the new sample and

the new log data is transmitted. Registers 489 and 491 can be used to control the data logger. To reset

the data logger, both register 489 and 491 should be set to 0 (or any other value in the allowable range

of memory).

Reading Register 16553 In ASCII Mode

Although register 16553 can be read in ASCII serial mode, it is not recommended if more than 10

channels of data are being logged (

see note below on buffer overflow problems

). Modbus mode is the

recommended mode to read large amounts of data logging memory. To read log data in other serial

modes, see

registers 493 to 523 and registers 8443 to 8450

Modbus Read Of 16553

10 channels or if using a uSD card with large numbers of samples. It provides a faster and more

efficient method of downloading large amounts of data than via the ASCII mode and does not suffer

from buffer overflow problems (

see note below

)

A read of register 16553 in Modbus mode produces a raw output format which needs to be decoded by

the user. The data bytes within the Modbus packet is formatted as follows;

Fixed Format Section

Data bytes 1 to 7 of each sample have a fixed format as follows;

1st data byte = Log trigger (see

)

2nd data byte = Date (see

)

3rd data byte = Month (see

)

4th data byte = Year (see

)

Data bytes 5-7 = Time stamp as 24 bit unsigned number in 1/100 second resolution.

Variable Format Section

Data bytes 8 and onwards do not have a fixed format. The format of these data bytes is determined by

the data logging configuration (i.e. how many registers are being logged and which type of registers are

being logged). The length of the data string is also effected by data logging configuration. To determine

how many registers need to be read and how to decode them, the user should first read register

16551, the data logging format register.

Writing To Register 16553

A write to register 16553 via the serial port can be used to log a custom text string into data logging

memory. The maximum length of the text string is governed by the values written to registers 4417 to

4432 as these effectively control the sample size. In ASCII mode the format would be;

SW16553,Hello World*

This allows text messages from another source to be time stamped and logged along with standard log

samples. Data logging must be enabled in the Meter Configuration Utility program for this feature to

2.6.10 Read Single Log Data at Log Read Pointer

ZEN-IOT-REG-MAN-16V04

function. (See

Code 8

)

A standard log sample can also be trigger from the serial port by writing any value (normally 0) to

the standard format.

Data Log Format - Register 16551

data.

Byte 1 = length of log format register (number of data bytes in packet)

Byte 2 = Internal sample size for data log in Flash memory.

Byte 3,4 = Controller software version (e.g. 403)

Byte 5 = Not Used in

Zen IoT

(always read as 0)

Byte 6 = Time format (current configuration of

Code_8

)_Byte 7,8 = Data log source register

Byte 9 = Register type

| repeated for each register that is logged

Byte 10 = Display format

Byte 11 = Alpha character

|-If the data logging configuration (see

Data Logging

and

Log Register Source - Registers 4275 to 4306

)

has been set up to log 4 registers per sample, then data bytes 7 - 11 will be repeated for each of the 4

logged registers.

The length byte defines how many bytes of data are contained in the data log format string.

The sample size byte gives the current data log sample size which is determined by the data logging

configuration.

The time format byte is basically a copy of Code 8 and specifies how the time/date information is to be

displayed.

The two data bytes which form the 16 bit data log source register define the register number of the

logged data. The register type byte defines the size and format of the data bytes in the log sample. The

different options available are;

0x00 = unsigned char

0x10 = signed char

0x20 = unsigned int

0x30 = signed int

0x40 = unsigned long

0x50 = signed long

0x60 = ASCII TEXT

0x70 = float

0x80 = unsigned 24 bit number(only 3 bytes long)

0x90 = signed 24 bit number(only 3 bytes long)

The display format and alpha character bytes define how the numeric value is to be displayed (i.e.

were the decimal point should be and what the trailing text character (if any) should be). (see

Display

Format Mode

for more info on how to interpret the display format byte)

NOTE:

When logging more than 10 registers per sample a buffer overflow can occur when downloading the

log data in the printer format via ASCII mode, resulting in truncated output data. If this happens, try

switching to spreadsheet format. If you are still experiencing problems then you should consider using

Modbus mode as described above.

ZEN-IOT-REG-MAN-16V04

Zen Registers81

log samples with a single command. A read of register 16555 outputs log data, starting at the sample

pointed to by the read pointer, and continues to output log samples until the read pointer equals the

write pointer, or the number of samples specified in register 4462 has been output. Each time it outputs

a log sample the read pointer is automatically incremented. At the end of the sequence, the read

pointer is equal to the write pointer. This command can also be used to read a selected block of log

samples by modifying the read pointer (register 491) and the write pointer (register 489) prior to

reading register 16555.

NOTE

: Register 16555 can only be read via the serial port in ASCII mode. To read log data in other

serial modes or from the macro, see

Zen IoT

controllers support additional relay output modules which can be fitted in the analogue channel

slots in place of analogue input/output modules. It is possible to order your

Zen IoT

in several

configurations which may contain combinations of analogue input channels, analogue output channels,

and relay output channels (please go to

www.defineinstruments.com

or contact your

Zen IoT

distributor

for order code options).

When the

Zen IoT

detects a relay output module in one of the channel slots, the functions for that

channel change from the standard analogue input functions to a relay output function and the 3 pin

channel connector now provides a single pole double throw (SPDT) relay contact output.

When the Zen IoT detects a relay output module in a channel slot, the functions for that channel

change from the standard analogue input function to a relay output function and the 3 pin channel

connector now provides a single pole double throw (SPDT) relay contact output.

Many of the registers associated with the channel are still valid however for some of them their

functionality changes.

The table below shows those existing registers whose functions are changed in analogue output mode.

Note:

The information shown above is only valid when the slot for an analogue channel has a relay

output module fitted. Although the registers shown above have the same register names and

addresses as those shown in the "Analogue Inputs" section, their function changes when a relay output

module is fitted in the channel slot.

When an analogue channel slot is fitted with a relay output module, the following registers are used to

configure the data source for each relay output. Each register is a 16 bit register which holds a Modbus

coil or switch register number. This allows you to associate each relay output with virtually any other

discrete input or output in the Zen IoT. The table below shows the register source values for different

discrete inputs and outputs and some special logical OR masks.

Note:

These same 16 registers are also used when analogue output modules are installed in channel

slots, however they point to completely different data sources. With relay modules installed they point

to discrete digital data flags. With analogue output modules installed they point to analogue registers

that contain integer values. It is possible that a Zen IoT may contain a combination of each so it is

important check what type of module is occupying a particular channel slot before accessing these

registers. The module type can be determined by reading the module ID code.
