Introduction 1

Introduction

1.1 Overview

The ADAM Series is a set of intelligent sensor-to-computer interface modules containing built-in microprocessor. They are remotely controlled through a simple set of commands issued in ASCII format and transmitted in RS-485 protocol. They provide signal conditioning, isolation, ranging, A/D and D/A conversion, data comparison, and digital communication functions. Some modules provide digital I/O lines for controlling relays and TTL devices.

Software Configuration and Calibration

ADAM modules contain no pots or switches to set. By merely issuing a command from the host computer, you can change an analog input module to accept several ranges of voltage input, thermocouple input or RTD input. All the module’s configuration parameters including I/O address, speed, parity, HI and LO alarm, calibration parameters settings may be set remotely. Remote configuration can be done by using either the provided menu-based software or the command set’s configuration and calibration commands.

By storing configuration and calibration parameters in a nonvolatile EEPROM, modules are able to retain these parameters in case of power failure.

Watchdog Timer

A watchdog timer supervisory function will automatically reset the ADAM modules in the event of system failure. Maintenance is thus simplified.

Power Requirements

Although the modules are designed for standard industrial unregulated

power supply , they accept any power unit that supplies power

24 V

within the range of +10 to +30 V

. The power supply ripple must be

limited to 5 V peak-to-peak, and the immediat e ripple v ol t age s h ould be maintained between +10 and +30 V

Connectivity and Programming

ADAM modules can connect to and communicate with all computers and terminals. They use RS-485 transmission standards, and communicate with ASCII format commands. The command set for every module type consists of approximately ten different commands.

ADAM 4000 Series User’s Manual

Chapter 1

The command set for input modules is larger because it incorporates alarm functions. All communications to and from the module are performed in ASCII, which means that ADAM modul es c an be programmed in virtually any high-level language.

RS-485 Network

The RS-485 network provides lower-noise sensor readings, as modules can be placed much closer to the source. Up to 256 ADAM modules may be connected to an RS-485 multi-drop network by using th e ADAM RS-485 repeater, extending the maximum communication distance to 4,000 ft. The host computer is connected to the RS-485 network with one of its COM ports through the ADAM RS-232/RS-485 converter.

To boost the network’s throughput, the ADAM RS-485 repeaters use a logical RTS signal to manage the repeater’s direction. Only two wires are needed for the RS-485 network: DATA+ and DATA-. Inexpensive shielded twisted pair wiring is employed.

Panel/DIN Rail mounting

Chapter 1 Introduction 1

Introduction

ADAM modules mount on any panel, on provided brackets, on DIN rails or may be stacked together.

The RS-485 network, together with screw-terminal plug connectors, allows for system expansion, reconfiguration and repair without disturbing field wiring.

Protection against the environment

Hardened plastic packing forms the outer shell of every module. Since all configuration is controlled by software, the module is not designed to be opened. This greatly enhances resistance against corrosive materials, moisture and vibration. ADAM modules’ low power requirements help them to operate in temperatures from 0 to 70

in humidities from 0 to 95% (non-condensing). They’re built compactly using automated SMT technology so you can pack them into watertight and explosion-proof industrial enclosures.

Installation Guideline 2

Installation Guideline

This chapter provides guidelines to what is needed to set up and install an ADAM network. A quick hookup scheme is provided that lets you configure modules before they are installed in a network.

To help you to connect ADAM modules with sensor inputs, several wiring examples are provided. Finally, you will find at the end of this chapter a programming example using the ADAM command set.

Be sure to carefully plan the layout and configur ation of your network before you start. Guidelines regarding layout are given in Appendix E: RS-485 Network.

NOTICE: Except for the communication modules, which have onboard switches for their baud rate setting, ADAM modules should not be opened. There is no need to open the ADAM modules: all configuration is done remotely and there are no user serviceable parts are inside. Opening the cover will therefore void the warranty.

2.1 System Requirements to set up an ADAM network

The following list gives an overview of what is needed to setup, install and configure an ADAM environment.

• ADAM modules

• A host computer, such as an IBM PC/AT compatible, that can output ASCII characters with an RS-232C or RS-485 port.

• Power supply for the ADAM modules (+10 to +30 V

• ADAM Series Utility software

• ADAM Isolated RS-232/RS-485 Converter (option a l)

• ADAM Repeater (optional)

)

Host computer

Any computer or terminal that can output in ASCII format over either RS-232 or RS-485 can be connected as the host computer. When only RS-232 is available, an ADAM RS-232/RS-485 Converter is re quired to transform the host signals to the correct RS-485 protocol. The converter also provides opto-isolation and transformer-based isolation to protect your equipment.

ADAM 4000 Series User’s Manual

Chapter 2

Power supply

For the ease of use in industrial environments the ADAM modules are designed to accept industry standard +24 V

Operation is guaranteed when using any power supply between +10 and +30 V

. Power ripples must be limited to 5 V peak to peak while the

voltage in all cases must be maintained between +10 and +30 V power supply specifications are referenced at module connector. When

modules are powered remotely, the effects of line voltage drops must be considered.

All modules use on-board switching regulators to sustain good efficiency over the 10-30 V input range, therefore we can assume that the actual current draw is inversely proportional to the line voltage. The following example shows how to calculate the required current that a power supply should be able to provide.

Assume that a +24 V

will be used to power five ADAM-4011 Analog

Input Modules. The distance from power supply to modules is not so big that significant line voltage drop will occur. One ADAM-4011 module consumes a maximum of 1.2 Watts. The total required power will equal 5 x 1.2 = 6 Watts. A power supply of +24 V

therefore be able to supply a minimal current of 6 / 24 = 0.25 Amps. Small systems may be powered by using wall-mounted modular power

supplies. Also when modules operate on long communication lines (>500 feet) it is often more reliable to power the modules locally with modular power supplies. These inexpensive units can easily be obtained from any electronics retail store.

The power cables should be selected according to the number of modules connected and the length of the power lines. When using a network with long cables, we advise the use of thicker wire to limit the line voltage drop. In addition to serious voltage drops, long voltage lines can also cause interference with communication wires.

+Vs (R) Red GND (B) Black

Communication Wiring

We recommend that shielded-twisted-pair cables that comply with the EIA RS-485 standard be used with the ADAM network to reduce interference. Only one set of twisted-pair cables is required to transmit both Data and RTS signals. We advice that the following standard colors (as indicated on the modules) be used for the communication lines:

DATA+ (Y) Yellow DATA- (G) Green

ADAM Utility Software

A menu-driven utility program is provided for ADAM module configuration, monitoring and calibration. It also includes a terminal emulation program that lets you easily communicate through the ADAM command set. (See Appendix D, Utility Software)

ADAM Communication Speed

In ADAM series, the baudrate can be configured from 1200 bps to 38.4 Kbps. And the baudrate of all modules in an RS-485 network must be the same.

ADAM 4000 Series User’s Manual

Chapter 2

ADAM Isolated RS-232/RS485 Converter (optional)

When the host computer or terminal has only a RS-232 port, an ADAM Isolated RS-232/RS-485 Converter, connected to the host’s RS-232 port, is required. Since this module is not addressable by the host, the baud rate must be set using a switch inside the module. The factory default setting is 9600 baud.

ADAM Repeater (optional)

When communication lines exceed 4000 ft (1200 meter) or the number of ADAM modules connected is more than 32, a repeater should be connected to expand the first segment. Up to 8 Repeater modules can be connected allowing connection of up to 256 ADAM modules. As with the Converter module, the Repeater module is not addressable by the host and the baud rate must be set by changing the switch inside the module. The factory default setting is 9600 baud.

2.2 Basic configuration and hook-up

Before placing a module in an existing network, the module should be configured. Though all modules are initially configured at the factory, it is recommended to check that the baud rate is set correctly.

Default Factory Settings

Baud rate: 9600 Bit/sec. Address: 01 (hexadecimal)

Chapter 2 installation Guideline 2

Installation Guideline

The following items are required to configure a module: an ADAM converter module, a personal computer with RS-232 port (baud rate set to 9600) and the ADAM utility software.

Configuration with the ADAM Utility Software

The easiest way to configure the ADAM module is by using the ADAM utility software: an easy-to-use menu-structured program will guide you through every step of the configuration. (See Appendix D, Utility Software)

Changing the protocol from ADAM ASCII to Modbus

Some ADAM-4000 modules support b ot h A DAM ASCII protocol and Modbus protocol . The factory default setting of these modules is ADAM ASCII protocol. If you would like to configure the modules to Modbus protocol, please refer to Appendix H which describe how to change the protocol in ADAM utility.

Configuration with the ADAM command set

ADAM modules can also be configured by issuing direct commands from within a terminal emulation program that is part of the ADAM utility software.

The following example guides you through the setup of an analog input module. Assume that an ADAM-4011 Analog Input module still has its default settings (baud rate 9600 and address 01h). Before the module is reconfigured, it is first requested to send its default settings.

NOTICE: An analog input module requires a maxi mu m of 7 seco nds to perform auto calibration and ranging after it is rebooted or powered on. During this time span, the module can not be addressed to perform any other actions.

Example:

Make sure that the module is properly connected as shown in figure 2-5. Power up all the connected devices, start the terminal emulation program, and issue the following command:

$012(cr)

requests that module with address 01 send its configuration status

!01050600

Module at address 01 responds that it is configured for an input range of +/-2.5 V, baud rate 9600, integration time of 50 ms (60 Hz), engineering units and no checksum checking or generation.

ADAM 4000 Series User’s Manual

Chapter 2

To change the configuration setting of the analog input module, the following command is issued:

%01070F0600(cr) % = change configuration 01 = target module at address 00 to: 07 = change address to 07 hexadecimal

0F = set input range to Type K thermocouple 06 = set baud rate to 9600 00 = set integration time to 50 ms (60 Hz)

disable checksum set data format to engineering units

(See Chapter 4, Command Set for a full description of the syntax of the configuration command for an analog input module)

When the module received the configuration command it will respond with its new address:

!07(cr) Wait 7 seconds to let the new configuration settings take effect before

issuing a new command to the module.

NOTICE: All reconfiguration except changing of baud rate and checksum values can be done dynamically, i.e. the modules need not to be reset. When changing the baud rate or checksum, these changes should be made for all connected devices. After reconfiguration, all modules should be powered down and powered up to force a reboot and let the changes take effect. See the next page for a strategy for changing baud rate and or checksum for an entire network.

2.3 Baud rate and Checksum

Adam modules contain EEPROMs to store configuration information and calibration constants. The EEPROM replaces the usual array of switches and pots required to specify baud rate, input/output range etc. All of the ADAM modules can be configured remotely through their communication ports, without having to physically alter pot or switch settings.

Chapter 2 installation Guideline 2

-7

Installation Guideline

Since there is no visual indication of a module’s configuration status, it is impossible just by looking at it what the baud rate, address and other settings are. It might not be possible to establish communications with a module whose baud rate and address are unknown. To overcome this problem, every module has an input terminal labeled INIT*. By booting the module while connecting the INIT* terminal with the module’s GND terminal, the modules configuration is forced into a known state. This state is called the INIT* state.

INIT* state defaults:

Baud rate: 9600 Address: 00h Checksum: disabled

Forcing the module in the INIT* state does not change any parameters in the module’s EEPROM. When the module is in the INIT* state with its INIT* and GND terminals shorted, all configuration settings can be changed and the module will respond to all other commands normally.

Changing Baud rate and Checksum

Baud rate and checksum settings have several things in common:

• They should be the same for all modules and host computer.

• Their setting can only be changed by putting a module in the INIT* state.

• Changed settings can only take effect after a module is rebooted

To alter baud rate or checksum settings you must perform the following steps:

• Power on all components except the ADAM Module.

• Power the ADAM module on while shorting the INIT* and GND terminals (See Figure 2-3).

ADAM 4000 Series User’s Manual

Chapter 2

Figure 2-3 Grounding the INIT* Terminal

• Wait at least 7 seconds to let self calibration and ranging take effect.

• Configure the checksum status and/or the baud rate.

• Switch the power to the ADAM Module OFF.

• Remove the grounding of the INIT* terminal and power the module on.

• Wait at least 7 seconds to let self calibration and ranging take effect.

• Check the settings (If the baud rate has changed, the settings on the host computer should be changed accordingly).

3.1 ADAM-4011/4011D Thermocouple Input Modules

ADAM-4011/4011D Thermocouple Input Modules use a microprocessor-controlled integrating A/D converter to convert sensor voltage, current or thermocouple signal into digital data. The digital data is then translated into either engineering units, two’s co mplement hexadecimal format or percentage of full-scale range (FSR) according to the module’s configuration. When prompted by the host computer, the data is sent through a standard RS-485 interface.

The ADAM-4011/4011D Thermocouple Input Modules offer signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from ground loops and power surges by providing opto-isolation of the A/D input and transformer based isolation up to 3000 V

transformer-based isolation up to 500 V

Open Thermocouple Detection and Input Surge Protection (ADAM-4011D only)

The ADAM-4011D provides an open thermocouple detection function. Users can use a simple command to detect whether the thermocouple is open or closed. The module also provides surge protection on its input channel. Internal high-speed transient suppressor on its input channel protects the module from dangerous spikes and voltages.

Front Panel LED Indicator (ADAM-4011D only)

The 4½ digits LED display on the back of the ADAM-401 1D let s yo u monitor process readings right at their source. The module displays readings in a wide variety of formats as well as high-low alarm messages. The ADAM-4011D offers flexibility, ease of installation and direct availability of process data. For critical process monitoring, this module is the ideal choice.

Digital Input/Output

ADAM-4011/4011D Thermocouple Input Modules also contain two digital outputs and one digital input. Outputs are open-collector transistor switches that may be controlled by the host computer. They can control solid-state relays, which in turn may control heaters, pumps, and other electrical powered equipment. The digital inputs may be read by the host computer and used to sense the state of a remote digital signal.

ADAM 4000 Series User’s Manual

Chapter 3

Event counting

The event counter is connected to the Digital Input channel and can be used to keep track of the total amount of external low-speed pulses. Its accumulated maximal count is 65535. The number 65535 is held, even if the actual number of events exceeds 65535. The counter can be read or reset to 0 by the host computer.

Since the Event counter’s data is not stored in EEPROM, the event counter is cleared and set to zero after every reset or power up of the analog input module.

Alarm signaling

Analog input modules include High and Low alarm functions. High and Low alarm limits may be downloaded into the module’s EEPROM by the host computer.

The alarm functions can be enabled or disabled remotely. When the alarm function is enabled, both Digital Output channels are used to indicate the High and Low alarm state. Digital Output channel 1 (DO1) equals High alarm state and Digital Output channel 0 (DO0) equals Low alarm state. The High and Low alarm states can be read at any time by the host computer.

Every A/D conversion will be followed by a comparison with the High and Low limit. When the input value exceeds one of these limits, the High or Low alarm state is set to ON.

There are two alarm mode options: Momentary and Latching. If the alarm is in Latching mode, the alarm will stay on even when the

input value returns within limits. An alarm in Latching mode can be turned OFF by issuing a Clear Alarm command from the host computer. A Latching alarm is cleared by the module when the opposite alarm is set. For example: the alarm is in latching mode and the High alarm is turned ON.

When the module receives a value that is lower than the Low alarm limit, it will clear the High alarm and turn the Low alarm ON.

When the alarm is in Momentary mode, the alarm will be turned OFF as soon as the input value returns to within limits.

The arrangement of coupling High and Low alarm states with Digital Output lines may be utilized to build ON/OFF controllers that can operate without host computer involvement.

Function Description for the ADAM-4011 analog input module

To provide a better understanding of the functioning of the ADAM modules, the following is a description of the module with the most extensive set of functions, the ADAM-4011.

All analog input data first flows through the PGA (programmable gain amplifier). The amplifier can vary its gain from 1 to 128. The PGA automatically adjusts the signal to a range of -2.5 V to +2.5 V. This ensures optimal input voltage and resolution for the A/D converter.

The A/D conversion is supervised by the microprocessor that holds the calibration software. Two kinds of calibration take place automatically on startup or reset: Auto Zero calibration and Auto Span calibration. Normal calibration is used to adjust the signal according to calibration parameters defined by the user.

The digital 10 Hz filter provides a steady state output by using the ΔΣ function.

Before the data enters the microprocessor it passes through an optical isolation device. The opto-isolation prevents ground loops and limits the chance of damage from power surges.

The microprocessor has six basic functions:

- Linearization of T/C (Thermocouple)

- Communication software and command set

- Calibration software

- Alarm monitoring

- Event counting

- Management of the EEPROM device that holds the system parameters

- Data transformation After data has been transformed to the right data format its is passed on

the RS-485 output port. If an input value exceeds the High alarm setting or falls below the Low

alarm setting, a flag is set in one of the Digital Output channels. Finally, the on-board switching regulator accepts voltage between +10

and +30 V protect your equipment from damage from power surges.

. This power circuit has an isolation value of 500 VDC to

The digital data is then translated into either engineering units, two’s complement hexadecimal format or percentage of full-scale range (FSR) according to the module’s configuration. When prompted by the host computer, the data is sent through a standard RS-485 interface.

ADAM-4012 Analog Input Modules offer signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from ground loops and power surges by providing opto-isolation of the A/D input and transformer based isolation up to 3000 V

Digital Inputs/Outputs

ADAM-4012 also contains two digital outputs and one digital input. Outputs are open-collector transistor switches that may be controlled by the host computer. They can control solid-state relays, which in turn may control heaters, pumps, and other electrical powered equipment. The digital inputs may be read by the host computer and used to sense the state of a remote digital signal.

Event counting

Since the Event counter’s data is not stored in EEPROM, the event counter is cleared and set to zero after every reset or power up of the analog input module.

3.9 ADAM-4021 Analog Output Module

Analog output module receives their digital input through an RS-485 interface from the host computer. The format of the data is either engineering units, two’s complement hexadecimal format or percentage of full-scale range (FSR), depending on the module’s configuration. It then uses its microprocessor-controlled D/A converter to convert the digital data into output signals. You get a true read-back of the analog output signal from the unit’s ADC, which independently monitors the output. You can specify slew rates and start up currents through the configuration software. The Analog Output Module can supply single-channel analog output in a range of voltages or currents. They protect your equipment from ground loops and power surges by providing opto-isolation of the D/A output and transformer based isolation up to 3000 V

Slew Rate

The slew rate is defined as the discrepancy between the number of milliamps (or Volts) per second of the present and the required output currents (or voltages). An ADAM analog output module may be configured for a specific slew rate.

3.10 ADAM-4024 4-channel Analog Output Module

ADAM-4024 is a 4-channel analog output with module mixed type module. Currently, there is not any ADAM-4000 series module providing more than one analog output channel. Under some circumstances, however, it is a demand for multiple analog outputs to fulfill particular applications without many duplicated modules. ADAM-4024 is designed to achieve this purpose by integrating four A/O channels and four isolated D/I channels into only one module. The four digital input channels function as interlock for emergency latch output.

ADAM-4024, inherited from both ADAM4019 the multi-channel universal A/I module and ADAM4021 multi-range A/O support, is allowed its four A/O channels working at the same time with different and more output ranges, e.g. 4 to 20 mA and +/- 10 V. To ensure the operation of machines and facilities, ADAM-4024 has the functionality of slew rate control. Output slope is programmable through ramping/clamping the slew rate. Unlike traditional mechanism, ADAM4024 permits start-up user value to substitute its default value. Users can easily set up and configure the module to be more adaptive and customized.

3.19 ADAM-4080/4080D Counter/Frequency Input Modules

ADAM-4080/4080D Counter/frequency input module has two 32-bit counter input channels (counter 0 and counter 1) with built-in programmable timer for frequency measurement. These cost-effective modules let you monitor counter/frequency data as measurements are taken.

Front Panel LED Indicator (ADAM-4080D only)

The 5-digit LED display of the ADAM-4080D lets you monitor its counter data right at the source. The module's LED display shows counter values as well as high-low alarm messages as a counter exceeds its programmed limits (direct display).

Another option is to display data send by the host computer. The module first sends counter data to the host computer for conversion or calculation. The host computer sends the data back to the ADAM4080D and the module shows it on the module's LED display (remote display).

Signal Input Mode

The ADAM-4080/4080D provides separate t erminals for photo isolated input and non-isolated input to simplify wiring. Opto-isolated input provides 2500 V

loops. After you make the physical connections, program the module to identify which of its two sets of input terminals it should activate (isolated or non-isolated terminals).

isolation to protect your equipment from ground

RMS

Programmable Digital Filter

The ADAM-4080/4080D module includes a unique programmable digital filter to reject noise on the input lines. You can specify separate time constants, such as minimum signal width at high level and minimum signal width at low level, to provide stable output readings.

Programmable Threshold

When the ADAM-4080/4080D is programmed for non-isolated input you can set a high and low trigger level. Like the programmable digital filter, the programmable threshold rejects noise on the input lines and provides stable input readings

ADAM 4000 Series User’s Manual

Chapter 3

External Control (Gate mode)

Besides the GND and counter terminal each channel has a gate terminal to connect an external gate signal. The gate signal (high or low) can trigger the counter to start or stop counting. The gate mode can be either low, high or disabled (low means that counting starts when the gate signal is low and stops when the gate signal becomes high)

Programmable Alarm Output

The ADAM-4080 module provides a configurable alarm for each counter. The ADAM-4080D provides high and low alarm functions for counter 0. When the counter reaches an alarm limit, it will trigger the built-in digital output for machine ON/OFF control. The alarm limits may be downloaded into the module's EEPROM by the host computer. The initial count value of ADAM-4080 module's counter can be configured as any v alues.

The alarm functions can be enabled or disabled remotely. When the alarm functions are enabled, digital output channels are used to indicate the alarm states. For ADAM-4080, digital output channel 0 equals the alarm state of counter 0, and digital output channel 1 equals the alarm state of counter 1. For ADAM-4080D, digital output channel 0 equals the low alarm state of the counter 0 and digital output channel 1 equals the high alarm state of the counter 0.

Every A/D conversion will be followed by a comparison with the alarm limits. If the input value exceeds one of these limits, the corresponding alarm state is set to ON.

There are two alarm mode options for the ADAM-4080D: momentary and latching. If the alarm is in latching mode, the alarm will stay on even when the input value returns within limits. An alarm in latching mode can be turned off by issuing a Clear Alarm command from the host computer. A latching alarm is cleared by the module when the opposite alarm is set. For example: the alarm is in latching mode and the high alarm is turned ON. When the module receives a value that is lower than the low alarm limit, it will clear the high alarm and turn the low alarm ON.

When the alarm is in Momentary mode, the alarm will be turned OFF as soon as the input value returns to within limits.

The arrangement of coupling high and low alarm states with digital output lines may be utilized to build ON/OFF controllers that can operate without host computer involvement.

Command Set 4

Command Set

4.1 Introduction

To avoid communication conflicts when several devices try to send data at the same time, all actions are instigated by the host computer. The basic form is a command/response protocol with the host initiating the sequence.

When modules are not transmitting they are in listen mode. The host issues a command to a module with a specified address and waits a certain amount of time for the module to respond. If no response arrives, a timeout aborts the sequence and returns control to the host.

Changing ADAM’s configuration might require the module to perform auto calibration before changes can take effect. Especially when changing the range, the module has to perform all stages of auto calibration that it also performs when booted. When this process is under way, the module does not respond to any other commands. The command set includes the exact delays that might occur when modules are reconfigured.

4.2 Syntax

[delimiter character][address][command][data][checksum] [carriage return]

Every command begins with a delimiter character. There are four valid characters: a dollar sign $, a pound sign #, a percentage sign % and an at sign @.

The delimiter character is followed by a two-character address (hexadecimal) that specifies the target module. The actual two character command follows the address. Depending on the command, an optional data segment follows the command string. An optional two character checksum may be appended to the total string. Every commands is terminated by a carriage return (cr).

ALL COMMANDS SHOULD BE ISSUED IN UPPERCASE CHARACTERS!

Before the command set, we provide the I/O module commands search table to help you find the commands you wish to use. The command set is divided into the following four subsections:

• Analog Input Module commands

• Analog Output Module commands

• Digital I/O and Relay Output Module commands

• Counter/Frequency Module commands

Every subsection starts with a command summary of the particular type of module, followed by datasheets that give detailed information about individual commands.

Although commands in different subsections sometimes share the same format, the effect they have on a certain module can be completely different than they have on another. For example, the configuration command: %AANNTTCCFF affects analog input modules and analog output modules differently. Therefore, the full command set for every module is listed.
