1.6.1 Module Power-up

At power-up, the module performs a check of its internal circuits, memory, and basic

User’s Manual Pub. 0300257-01 Rev. A

1-4 Point IO™ 2/4 Channel Analog HART Module

functions. If no faults ar e found during power-up diagnostics, the module status LED is turned on.

After power-up checks are complete, the module waits for valid channel configuratio n data. If an invalid configuration is detected, the module will generate a PLC fault. Once a channel is properly configured and enabled, it continuously converts the input data to a value within the range selected for that channel.

1.6.2 Module Operation

The 1734sc-IE2CH and IE4CH modules are single ended 4-20mA current sensing input modules with HART master capability. Analog current is measured by sensing voltage drop across an internal resistor. The nominal input resistance of individual channels is 250ohms. In the event of an over-current fault the module will protect the input circuitry by increasing the input resistance to limit input current. Analog to digital conversion is performed by a multiplexed Sigma-Delta ADC shared by all channels. A range of notch filters as well as an averaging filter can be applied to analog inputs. All channels share a common ground. Field power is provided on the terminal block to simplify wiring. The 1734sc-IE2CH and IE4CH have HART Primary Master capability. A dedicated HART modem is used for each channel for maximum throughput. When HART functionality is enabled on a channel the module will discover and establish communication with HART revision 5 and greater devices. Once communication has been established the module will automatically gather HART PV, SV, TV, FV data and monitor device status. The modules pro vide a communication br i dge to HART devices for Asset Management Software and Ladder Programs via CIP messaging.

The 1734sc-IE2CH and IE4CH allow, in addition to reading the 4 to 20 mA analog signal, the ability to read and write HART data to and from HART compatible devices. This chapter will describe how to configure the IExCH module using RSLogix 5000 programming software.

The module produces and consumes data as follows:

IE2CH Produce/Consume Data

Input Assembly Options I/O Connection Type Consumes Produces

Analog + HART 0, 1 Change-of-State 0 Bytes 60 Bytes

IE4CH Produce/Consume Data

Input Assembly Options I/O Connection Type Consumes Pr oduces

Analog + HART 0, 1, 2, 3 Change-of-State 0 Bytes 112 Bytes

The IExCH module is not compatible with the 1734-ADN, ADN(X), and

limit of 600 bytes. Therefore, the maximum number of 1734sc-IE4CH modules that can be installed behind a ControlNet adapter is four and the maximum number of 1734sc-IE2CH modules is eight.

Section 3.3 Use Generic Profile

The generic point IO module profile can be used to represent the IExCH module within RSLogix 5000. The generic profile should be used for RSLogix 5000 versions 14 and older. Before the generic profile can be added to the IO configuration, the proper communication module needs to be added to the IO configuration first. Follow the procedure below to add a communication module to RSLogix 5000.

1.) Add the new local communication module to your project.

2.) Configure the local module, including: a. Naming the module b. Choosing a Communication Format c. Setting the Revision level d. Setting the module location as necessary such as the slot number for a

1756-CNB module

e. Choosing an Electronic Keying method

3.) Add the new remote module to your project, such as a 1734 Control Net adapter

or Ethernet Adapter (i.e. 1734-ACNR or 1734-AENT, respectively).

4.) Configure the remote module similarly to the local module

5.) Download the configuration to the controller

Note: If you are using Control Net, you must schedule the network using “RSNetworks for Control Net” after adding the local and remote communication modules.

Note: When you create a new RSLogix 5000 project with the CompactLogix 1769-L32C or L35CR controller, The Controller Organizer creates a Control Net port in the local chassis. In this case, you don’t need to add a separate local communication module.

Note: When you create a new RSLogix 5000 project with the CompactLogix 1769-L23E, 1769-L32E or L35E controller, The Controller Organizer creates a Ethernet port in the local chassis. In this case, you don’t need to add a separate local communication module.

3.3.1 Add a Local Ethernet Bridge Module

After you have started RSLogix 5000 software and created a controller project, you can add Ethernet communication modules. A local Ethernet communication module is a module that resides in the same chassis as the controller.

1.) Select a New Module for the I/O Configuration.

Section 4.1 HART Features

Chapter 4 IExCH and HART

This chapter describes how to read and write HART data using the IExCH module. This chapter includes the following sections:

• HART features

• Detecting HART devices

• Auto scanning of HART dynamic variabl es

• Supported HART CIP messages

The IExCH module will function as a HART master and will communicate with HART devices running HART r evision 5 or greater. Ther IExCH module includes one H ART modem per channel to provide maximum acquisition speed and flexibility. The block diagram in section 1.6.2 describes the internal architecture of the module including the placement of the HART modems. The module performs the following HART operations:

• Automatically reads the four dynamic HART variables PV,SV,TV, and FV

• Automatically retrieves and stores HART device information including,

manufacturer’s ID, device tag name, HART revision level, etc., and makes the information available via a CIP unconnected message

• The module automatically retrieves and stores extended device status, using

HART command 48. The extended status can be retrieved using an unconnected CI P messa ge.

• A HART pass-through interface using CIP unconnected messaging provides the

ability for the user, or remote client, to send a HART command to a HART enabled device.

Section 4.2 Detecting HART Devices

HART communication can be enabled independently on each channel. For more information on configuring HART on a specific channel, refer to Chapter 3. When a channel is enabled for HART, the IExCH module will act as a primary HART master and the HART enabled field device will act as a HART slave. Any given channel may have a master (i.e. the IExCH), a secondary master (hand held configuration tool), and a slave device connected simultaneously. Please see figure below.

User’s Manual Pub. 0300257-01 Rev. A

4-2 Point IO™ 2/4 Channel Analog HART Module

Figure 4-1

To determine if a HART device is present on a given channel the module will continuously send out HART command 0 if the channel is enabled for HART. Short frame addressing is used on command 0 and the polling add r ess will be incremented in the following manner:

0,1-15,16-63, 0

Once the module receives a reply to command 0 it will start its connection sequence to populate its internal cache of device data for that channel and then proceed to scanning of the dynamic variables and processing pass-through requests. The data acquisition process is described in the flow chart shown on the following page.

4.2.1 Auto-Scanning of Dynamic HART Variables (PV, SV, TV, FV)

The module will continuously send Cmd 3 or Cmd 9 to the HART device connected on a channel. Which command is sent is determined by the HART Universal revision number of the HART device. If the device has a revision of 6 or greater then Cmd 9 is used, otherwise for HART revision 5 devices Cmd 3 is used. The advantage of Cmd 9 is that it contains a “Health Status” byte for each of the 4 dynamic variables that it returns. The Dynamic variables and the status bytes are published in the module input ta gs. See Section 3.6 for more information.

4-4 Point IO™ 2/4 Channel Analog HART Module

Section 4.3 Supported HART CIP Messages

CIP messages can be sent to the module using the MSG instruction to retrieve additional HART information that is not included in the module’s input tags. This data may include, additional HART device information, HART d evice extended stat us, H ART pass-through messaging, or the ability to temporarily suspend/resume HART communication on any given channel. The available HART CIP messages include:

Topic Page

Read Additional Device Status 4-4 Get HART device information 4-6 HART pass-through messaging 4-9 Flush Queue 4-14 Suspend HART communication 4-14 Resume HART communication 4-15

4.3.1 Read Additional Device Status

Most devices support HART command 48 which allows the HART primary or secondary master to read additional device status information. HART command 4 8 is optional for devices running HART revision 5 & 6, but is required for devices running revision 7. Command 48 returns up to 25 bytes of status information. This group of 25 bytes includes both pre-defined status bytes and device specific status.

The IExCH will keep an internal cache of each channels Command 48 status data and make the data available via a CIP unconnected message. The IExCH keeps the data up to date by monitoring the MSA (More Status Available) bit (i.e. bit 4 in the Field Device Status Byte). See Error! Reference source not found. and Error! Reference source not found. for more information. When the MSA changes state (i.e. changes from 0 to 1 or 1 to 0), the module will resend command 48 on the associated channel. If the MSA bit remains set, the module will resend command 48 to the device every 2 minutes.

The SUA (Status Update Available) bit is used to notify the user that add itional status for The SUA (Status Update Available) bit is used to notify the user that add itional status for the channel has been refreshed by the module and the user should re-send the “Read Additional Device Status” CIP message to retrieve the cached data. After the CIP message is sent, the bit will clear.

Note: The data returned by the “Read Additional Device Status” message is in the original order as received from the HART device which means any multi-byte elements in the data will be reversed in the PLC. Hart format is MSB first and the PLC is LSB first for multi-byte variables. Since the location of the multi-byte elements can vary depending on the device, the module will not be able to reorder the bytes. Refer to the HART device’s documentation for the location of each multi-byte element and reverse the order of the bytes in ladder to interpret.

The module will update its internal data cache for command 48 under the following conditions:

4.3.2 Get HART Device Information

When a HART device is first connected to the module, the module will send a series of HART commands to retrieve information about the device. This device information is held in the module’s cache memory and can be retrieved by sending an unconnected CIP message. The following table lists the commands that are sent by the module when the device is first connected.

If the connected HART device’s configuration changes, the device will set the ”configuration changed” bit (i.e. bit 6 of the Field Device Status byte). When the IExCH detects that the “configuration changed” bit is high, it will automatically re-send the appropriate HART commands to refresh the device information stored in its cache memory. See Table 4-6. The first command sent is command 38 which will reset the “configuration changed” bit in the device.

4.3.3 HART Pass-through Messaging

The HART Pass-Through Command can be used to send any HART command including universal, common practice or device specific, directly to a field device via ladder.

All HART pass-through commands require a series of messages to be exchanged. First, a pass-through init must be sent to the HART module to initiate the pass-through command. The HART module will respond to the request with a request rep ly that includes a handle that can be used to obtain the pass-through message response. Once the handle is received, the user may issue a pass-through query to obtain the status of the

User’s Manual Pub. 0300257-01 Rev. A

4-10 Point IO™ 2/4 Channel Analog HART Module

pass-through command and the pass-through response data, if available. There is a handle timeout associated with the final reply message. After the HART

module obtains the requested information from the HART d evice, it will start a handle timeout timer. Refer to section 3.5.4for information regarding how to set the handle timeout. The reply message will be cached in memory during the handle timeout period. When the handle timeout timer expires the reply message will be discarded, and another pass through message will be serviced without being rejected. The user defined handle timeout is in the range of 1 to 255 seconds.

If the HART message being sent or received using the pass-through

Attention

Depending on the HART command, the data contained within the HART message may include floating point numbers or double integers. If a floating point or double integer is contained within the HART message, the user must be aware that the order of the bytes that make up the float or double will need to be reversed. The reason for this is related to how the bytes are stored in the PLC.

The PLC stores the bytes in memory in a format referred to as "little-endian". Littleendian is an order in which the "little end" (least significant value in the seque nce) is stored first (at the lowest storage address). However, HART devices transmit the byte data in the reverse order or as you may have guessed "big-endian".

command contains double-words or floating point values, the order of the bytes must be reversed.

The HART Pass-through “Reason Code” is a value that is reported when a Pass-through reply message returns the general “Status” value as 35 (DR_DEAD). It provides the user a diagnostic code, which is referenced in the table below, describing the possible cause of the failure. This code will be returned in offset 3 of the reply message for Pass-through Init or Query messages whenever the “Status” value at offset 0 is equal to 35 (DR_DEAD).

The Flush Queue message can be sent to have the IExCH module discard any pending HART replies awaiting a query command. These replies are automatically discarded once the handle timeout period has expired. The handle timeout period is defined in the module configuration. The default value assigned by the AOP is 20 seconds. Unless you need to discard the replies faster than 20 seconds, you won't need to use this Flush Queue command.

Appendix B Additional HART Protocol Information

This appendix describes the HART p rotocol and provides references for additional information about the protocol. Consult the HART protocol specification and vendor provided documentation for specifics on HART commands.

This appendix provides the following:

• HART protocol background information

• Common practice command sets

• Extended command sets

• References to additional information

HART Field Communication Protocol is widely accepted in the industry as the standard for digitally enhanced 4…20mA communication with smart field instruments. The HART Protocol message structure, command set, and status are discussed in this appendix.

The HART command set is organized into these groups and provides read and write access to a wide array of information available in smart field instruments:

• Universal commands provide access to information that is useful in normal plant

operation such as the instrument manufacturer, model, tag, serial number, descriptor, range limits, and process variables. All HART devices must implement universal commands.

• Common practice commands provide access to functions that can be carried out

by many devices.

• Device specific commands provide access to functions that can be unique to a

particular device.

Section B.1 Message Structure

Read this section for a description of transaction procedure, character coding, and message structure of the HART protocol. These correspond to layer 2 (datalink layer) of the OSI protocol reference model.

B.1.1 Master-slave Operation

HART is a master-slave protocol. This means that each message transaction is originated by the master; the slave (field) device replies when it receives a command message addressed to it. The reply from the slave device acknowledges that the command was received and can contain data requested by the master.

B.1.2 Multiple Master Operation

The HART protocol provides for two active masters in a system: one primary and one secondary. The two masters have different addresses. Each can positively identify replies

User’s Manual Pub. 0300257-01 Rev. A

B-2 Point IO™ 2/4 Channel Analog HART Module

to its own command messages. The 1734sc-IE2CH or 1734sc-IE4CH module acts as primary master. A secondary master, such as a handheld configuration device , may also be connected.

B.1.3 Transaction Procedure

HART is a half-duplex protocol. After completion of each message, the FSK carrier signal must be switched off to let the other station trans mit. The carrier control timing rules state that the carrier should be turned on not more than 5 bit times before the start of the message (that is, the preamble) and turned off not more than 5 bit times after the end of the last byte of the message (the checksum).

The master is responsible for controlling message transactions. If there is no reply to a command within the expected time, the master should retry the message. After a few retries, the master should abort the transaction, because presumably the slave device or the communication link has failed.

After each transaction is completed, the master should pause for a short time before sending another command, to provide an opportunity for the other master to break in if it wishes. This way, two masters (if they are present) take turns at communicating with the slave devices. Typical message lengths and delays allow two transactions per second.

B.1.4 Burst Mode

Burst mode is not supported.

Section B.2 Response Code and Field Device Status

Two bytes of status also called the response code and field device status are included in every reply message from a field or slave device. These two bytes convey communication errors, command response problems, and field device status. If an error is detected in the outgoing communication, the most significant bit (b it 7) of the first byte is set to 1 and the details of the error are reported in the rest of that byte. The second byte, in this case, is all zeros.

Communication errors are typically those that would be detected by a UART (parity overrun and framing errors). The field device also reports overflow of its receive buffer and any discrepancy between the message content and the checksum received.

In RSLogix 5000 software, if the leftmost bit of the ResponseCode is set, it displays a negative number. In this case, the ResponseCode represents a communication fault. Change the display format to hexadecimal to interpret communication status.

If the leftmost bit of the ResponseCode is 0 (value 0…127), then there was no communication error and the value is a ResponseCode from the HART field device. Response codes indicate if the device performed the command. 0 means no error. Other values are errors or warnings. To understand the ResponseCode, contact your HART field device manufacturer or the HART specification.

See Table B-1and Table B-2 for descriptions of the response code and the field device status.

Section B.3 HART PV, SV, TV, and FV Status

HART PV, SV, TV, and FV are dynamic variables that contain the values of device variables, which are various direct or indirect process measurements performed by the HART field device.

Some devices let a set of their internal device variables be mapp e d to the PV, SV, T V, FV dynamic variables that are automatically collected in the 1734sc-IExCH Input Tag.

HART PVStatus, SVStatus, TVStatus, FVStatus are known as Device Variable Status values. These Status values are composed of groups of bits that indicate the quality of the associated device variable.
