1. COMMUNICATION FUNCTIONS

1.1 Outline

▪ Via RS-485 interface and PC loader interface, PXH provides communication functions of transmit-

ting and receiving data to and from host computer, programmable controller, graphic panel, etc.

▪ The communication system consists of master station and slave stations. For RS-485 communica-

tion, up to 31 slave stations (PXHs) can be connected per master station.

Note that, because the master station can communicate with only one slave station at a time, a party

to communicate with must be specified by the "Station No." set at each slave station.
For loader communication, one slave station (PXH) can be connected per master station.

▪ In order that the master station and slave station can communicate, the format of the trans-

mit/receive data must coincide. For the PXH, the format of the communication data is determined
by the MODBUS protocol.

▪ Please use an RS-232C ⇔ RS-485 converter in case of designating a personal computer or other

devices which have an RS-232C interface as a master station.
［RS-232C ⇔ RS-485 converter］ (recommended article)

Type: RC-77 (isolated type)/ RA SYSTEMS make http://www.ras.co.jp
Type: K3SC-10 (isolated type)/ OMRON make http://www.omron.co.jp

RS-232C communication with PC is available upon connecting Type: ZZPPXH1*TK4H4563 to PC

Caution:

When using the RS-232C ⇔ RS-485 converter, pay attention to cable connection between the con-

verter and master station. If the cable is not connected correctly, the master station and slave station

cannot communicate. In addition, be careful about communication settings such as baud rate and
parity set for the converter.

3.2 Wiring

■ RS-485

▪ Use twisted pair cables with shield. Recommended: KPEV-SB (Furukawa Electric make)

▪ The total extension length of the cable is up to 500 m. A master station and up to 31 units of the

PXH can be connected per line.

▪ Both ends of the cable should be terminated with terminating resistors 100Ω (1/2W or more).

▪ If the PXH is to be installed where the level of noise applied to the PXH may exceed 1000 V, it is

recommended to install a noise filter in the master station side as below.
Recommended noise filter: ZRAC2203-11 (TDK make)

▪ If problematic in EMC at communication, loading the communication cable with ferrite can lower

the noise level.

Recommended ferrite core: ZCAT series (TDK make)

4. SETTING OF COMMUNICATION CONDITION

In order that the master station and instrument (PXH) can correctly communicate, following settings are re­quired.

▪ All communication condition settings of the master station and those of instruments (PXH) are indentical.

▪ For RS-485 communication, different "station numbers (STN4)" are assigned to all PXHs which are con-

nected to a common line. (Any "Station No." is not shared by more than one instrument.)

▪ For PC loader communication, the station No. is fixed at "1".

Both for PC loader communication and RS-485 communication, same station No. "1" may be assigned.

5. MODBUS COMMUNICATION PROTOCOL

5.1 Outline

The communication system by the MODBUS protocol is that the communication always starts from
the master station and a slave station responds to the received message.

Transmission procedures is as shown below.

1) The master station sends a command message to a slave station.

2) The slave station checks that the station No. in the received message matches with the own station No.

or not.

3) If matched, the slave station executes the command and sends back the response message.

4) If mismatched, the slave station leaves the command message and wait for the next command
message.

a) In case when the station No. in the received command message matches with the own slave

station No.

Master to slave

Slave to master

b) In case when the station No. in the received command message mismatches with the own

slave station No.

Master to slave

Slave to master

The master station can individually communicate with any one of slave stations connected on the
same line upon setting the station No. in the command message.

5.2 Composition of Message

Command message and response message consist of 4 fields; Station No., Function code, Data and
Error check code. And these are sent in the following order.

Station No. (1 byte)

Function code (1 byte)

Data (2 to 69 bytes)

Error check code (CRC-16) (2 bytes)

Fig. 5-1 Composition of message

In the following, each field is explained.

(1) Station No

Station No. is the number specifying a slave station. For RS-485 communication, the command

is processed only by the slave station whose station No. matches with the No. set in the parame­ter "STN4".

For details of setting the parameter "STN4", refer to chapter 4.

For PC loader communication, the station No. is fixed at "1".

(2) Function code

This is a code to designate the function executed at a slave station.

For details, refer to section 5.4.

(3) Data

Data are the data required for executing function codes. The composition of data varies with
function codes. For details, refer to chapter 6.

A register number is assigned to each data in the indicating controller. For using the data by

communication, designate the register number.

Note that the register number transmitted on message is expressed as its relative address.

The relative address is calculated by the following expression.

Relateve address



The lower 4 digits of the

＝




Register number



– 1




For example, when the resister number designated by a function code is 40003,

Relative address = (lower 4 digits of 40003) – 1

= 0002
is used on the message.

INP-TN514207-E

9

(4) Error check code

This is the code to detect message errors (change in bit) in the signal transmission.

On the MODBUS protocol (RTU mode), CRC-16 (Cycric Redundancy Check) is applied.

For CRC calculation method, refer to section 5.5.

INP-TN514207-E

10

5.3 Response of Slave Station

(1) Response for normal command

To a relevant message, the slave station creates and sends back a response message which corre-

sponds to the command message. The composition of message in this case is the same as in

section 5.2.

Contents of the data field depend on the function code. For details, refer to Chapter 6.

(2) Response for abnormal command

If contents of a command message have an abnormality (for example, non-actual function code is

designated) other than transmission error, the slave station does not execute that command but
creates and sends back a response message at error detection.

The composition of response message at error detection is as shown in Fig. 5-2. The value used
for function code field is function code of command message plus 80

5.5 Calculation of Error Check Code (CRC-16)

CRC-16 is the 2-byte (16-bits) error check code. From the top of the message (station No.) to the

end of the data field are calculated.

The slave station calculates the CRC of the received message, and does not respond if the calculated
CRC is different from the contents of the received CRC code.

Fig. 5-3 shows the flow of the CRC-16 calculation system.

Set FFFFH (hexadecimal number) in CR.

Exclusive logical sum (XOR) is executed
with CR and one character (1 byte) of the I
characters, and its results is set in CR.

CR calculation result shall be added
to the last command message in the
order of LOW byte and HIGH byte.

5.6 Transmission Control Procedure

(1) Transmission procedure of master station

The master station must proceed to a communication upon conforming to the following items.

(1-1) Before sending a command message, provide 48 bits time or more vacant status.

(1-2) For 1 command message, each field part should be sent below 24 bits time interval.

(1-3) Within 24 bits time after sending a command message, receiving stand-by status

starts.

(1-4) Provide 48 bits time or more vacant status between the end of response message re-

ception and beginning of next command message sending [same as in (1-1)].

(1-5) For ensuring the safety, make a confirmation of the response message and make an

arrangement so as to provide 3 or more retries in case of no response, error occur­rence, etc.

Note) The above definition is minimum requirement. For ensuring the safety, it’s recom-

mended the program for the master should be developed with 2 to 3 times margins.

Concretely, it is advised to arrange the program for 9600 bps with 10 ms or more for

vacant status (1-1), and within 1 ms for byte interval (1-2) and changeover from
sending to receiving (1-3).

(2) Description

1) Detection of the message frame

2) Response of this instrument (PXH)

Since the communication system uses the 2-wire RS-485 interface, there may be 2 statuses
on a line below. (The same goes with PC loader communication.)

(a) Vacant status (no data on line)

(b) Communication status (data is existing)

Instruments connected on the line are initially at a receiving status and monitoring the line.

When 24 bits time or more vacant status has appeared on the line, the end of preceding frame

is assumed and, within following 24 bits time, a stand-by status is posted. When data ap-

pears on the line, the instruments enter on receiving, and when 24 bits time or more vacant

status is detected again, and the end of that frame is assumed. I.e., data which appeared on

the line from the first 24 bits time or more vacant status to the next 24 bits time or more va­cant status is fetched as one frame.

Therefore, one frame (command message) must be sent upon confirming the following.

(1-1) 48 bits time or more vacant status precedes the command message sending.

(1-2) For 1 command message, each byte should be sent below 24 bits time interval.

After a frame detection (24 bits time or more vacant status is detected), this instrument car-

ries out processing with that frame as a command message. If the command message is ad-

dressed to the own station, a response message is returned. Its processing time is about 10
ms (depends on contents of command message).

After sending a command message, therefore, the master station must observe the following

(1-3) Stand-by status is posted within 24 bits time after sending a command message.

5.7 FIX Processing (Cautions in data write)

The instrument is provided inside with a non-volatile memory (EEPROM) for holding the setting pa-

rameters. Data written in the non-volatile memory is not lost even if turning off the power.

To hold parameters that were written in the internal memory via communication after turning off the
power, the FIX process is effective. It allows parameters to be written in nonvolatile memory.

Fig. 5-4 shows the FIX procedure.

Cautions:

▪ FIX processing takes approximately 5 seconds to 3 minutes (depending on how many parameters

were changed).

▪ While writing, do not turn off the power of the PXH. Otherwise, the data in the non-volatile

memory will be destroyed, whereby the PXH could not be used any longer.

▪ Don’t change parameters on the front panel when performing the FIX procedure, or memory error

may result.

▪ The non-volatile memory (EEPROM) is a device where the number of write-in times is limited.

The guaranteed number of write-in times of the non-volatile memory used on the instrument is

100,000 minimum. Therefore, limit the times of FIX processing to bare minimum, like when set-

ting parameters are changed. Refrain from carrying out the FIX processing periodically for exam­ple or while such is not absolutely required.

Words data are read-out, starting from read-out start No. until read-out word number. The slave
station transmits the read-out word data in the order of upper and lower bytes.

For PXH for which all data consists of 2 word units, data should be read out by units of 2 words.

(2) Function explanation

Words data are read-out, starting from read-out start No. until read-out word number. The slave
station transmits the read-out word data in the order of upper and lower bytes.

For PXH for which all data consists of 2 word units, data is read out by units of 2 words.

Point

Since the transmission data can not include a decimal point, data of 100.0 is
transmitted as "1000".
For transmission format of each data, refer to the address map (Chapter 7).

When setting is being locked, response is returned normally. However, the

7. ADDRESS MAP AND DATA FORMAT

7.1 Data Format

7.1.1 Transmission data format

The MODBUS protocol used in this instrument (PXH) is RTU (Remote Terminal Unit) mode.

Transmitted data is "numeric value" and not "ASCII code".

7.1.2 Engineering unit

This instrument can handle set value data or other data which are affected by input range as follows.

Engineering unit: Subjected to scaling to match the actual value according to input range

[Example] The value of "PV = 150" (input range: 0º to 400ºC)

Register No. Data (HEX) Data (decimal)

Engineering unit 0102 00000096H

● How to change the input range setting via communication

The input range setting is for full scale, base scale and decimal point position setting.

In order that the change of input range setting will affect the control, power must be turned off and
on, or the reset command must be executed.

Changing the decimal point position automatically changes the full scale and base scale settings.

Example: Changing the input range from 0 to 400, to 0.0 to 400.0

(1) PV1D = 0 → 1 (automatically changes as PV1F = 400 → 400.0, PV1B = 0 → 0.0)

↓

(2) FIX command (see 5.7)

↓

(3) Power OFF-ON or execute reset command (write 1 at relative address 0060H)

● Input range dependent data (see communication address map)

Input range dependent data must be reset after turning off and on power or after transmitting a reset
command subsequent to a change of input range.

(1) Input range setting change

↓

(2) FIX command (see 5.7)

↓

(3) Power off and on or execute reset (write 1 at relative address 0060H)

↓

(4) Reset all data depending upon by input range

7.1.3 Handling of decimal point

No decimal point is added to transmission data.

For data given in the following table, carry out an alignment of decimal point. (Decimal point

should be removed in transmission, and should be added in receiving data.)

8. SAMPLE PROGRAM

This section concerns data read-out/write-in sample program by Microsoft Visual Basic 6.0 (SP6) (enclosed
to CD-ROM).

Note that the program shown here is for reference for you to create a program and not for guaranteeing all
actions.

Before executing the program, make sure of the communication conditions in the following procedure.

▪ Parity, communication speed: Must be set in this program to match the instrument.

Precautions for some RS-232C ⇔ RS-485 converter

The transmission data itself may precede the answer data from the slave station. In such a case, discard

as many data as transmission bytes found there, and then process it as answer data.

Applicable OS

Windows 2000 Professional

Windows XP Professional Edition

Fuji Electric Systems Co., Ltd. and Fuji Electric Instruments Co., Ltd. will not be responsible for damages

attributable to use of the sample program nor infringement of rights owned by third parties.

Use the program upon admitting the above.

If the communication is unavailable, check the following items.

□ Whether all devices related to communication are turned on.

□ Whether wirings are correct. (Whether polarities are correct.)

□ Whether the number of connected instruments and connection distance are as specified.

□ Whether communication conditions coincide between the master station (host computer) and slave sta-

tions (PXH).

□ Transmission speed : 9600bps, 19200bps, 38400bps

□ Data length : 8 bits

□ Stop bit : 1 bit

□ Parity : □ odd

□ even

□ none

□ Whether send/receive signal timing conforms to Section 5.4 in this manual.

□ Whether the station No. designated as send destination by the master station coincides with the station No.

of the connected PXH. (For PC loader communication, the station No. is fixed at "1".)

□ Whether, at RS-485 communication, more than one instrument connected on the same transmission line

does not share the same station No.

□ Whether, at RS-485 communication, the station No. of instruments is not set at 0.

If it is 0, the communication function does not work.

□ Whether, at RS-485 communication, the 11th digit of type code of this controller is R.

(PXH9□□□□ – □□R□□－□)

□ Whether, at RS-485 communication, settings of communication conditions for RS-232C ⇔ RS-485 con-

verter are correct.
