This paging scheme uses the module’s input and output words to transfer data between the controller and the module, 38 bytes at a time (i.e. one page at a time). The paging scheme is utilized to minimize the number of bytes sent and received at one time from the module’s input and output image.
7-12 Compact IO™ Isolated HART Analog Input Module Words 4…23 (Message Request Buffer) The message request buffer contains the data being sent to the module for the current page (up to 38 bytes). 7.3.2 Module Input Tags Used For Messaging The module utilizes 22 input words to receive messages and control data flow. The table below shows the input words used by the module. Refer to Chapter 6 for more information regarding input words 0 through 27.
Chapter 7: Enabling and Using HART on the 1769sc-IF4IH0 7-13 Words 30…49 (Message Response Buffer) The message response buffer contains the response data for the current page up to thirty eight bytes at a time. 7.3.3 Processing a Message To complete a message from beginning to end, follow the steps listed below: 1. Store the message you wish to send to the module in an array. Remember the message can be up to 257 bytes long, so make the array large enough. 2.

7-30 Compact IO™ Isolated HART Analog Input Module Section 7.4 Module Specific Commands The HART input module uses module specific commands. Module specific commands include the HART pass-through, HART suspend and resume, and get HART device information. The commands are passed to the module using the input and output image. Since some messages can be as long as 257 bytes, the data is transported to and from the module 40 bytes at a time using the paging scheme described in the previous section.

7-44 Compact IO™ Isolated HART Analog Input Module HART revision 5 introduced the long frame format. In this format, the address of a slave device is a worldwide, unique 38-bit number derived from the manufacturer code, the device type code, and the device identification number. The long frame format provides extra security against acceptance of commands meant for other devices, due to external interference or excessive crosstalk. The IF4IH supports only the long frame format.
Chapter 7: Enabling and Using HART on the 1769sc-IF4IH0 7-45 The 1 byte Device Type code is allocated and controlled by the manufacturer. The 3 byte Device Identifier is similar to a serial number in that each device manufactured with the same Device Type Code must have a different Device Identifier. The IF4IH automatically pulls for the device specific codes using the Auto-acquisition process. The device specific codes that are acquired using this process can be seen in Table 2.

Chapter 8 Programming Examples This chapter provides ladder samples for general and advanced applications using the 1756sc-IF4IH module. Ladder samples for both the CompactLogix and MicroLogix 1500 PLC are discussed in this chapter. Section 8.1 CompactLogix 8.1.1 Reset/Reconfig The following rungs of ladder demonstrate how to either reset the module (Backplane connection will be broken) or reconfigure the module without breaking the connection. Figure 8-1 (Reconfig) User's Manual 0300215-03 Rev.
8-2 Compact IO™ Isolated HART Analog Input Module Figure 8-2 (Reset) User's Manual 0300215-03 Rev.
Chapter 8: Programming Examples 8-3 8.1.2 Swap Byte Order This ladder sample demonstrates how to reverse the order of the bytes for a floating point tag and then convert it to 4 consecutive SINT tags, so that it can be used in a HART message. If the HART message being sent or received using the pass-through command contains floating point values, the order of the bytes must be reversed. ! Attention Figure 8-3 (Change Byte Order) 8.1.
8-4 Compact IO™ Isolated HART Analog Input Module The algorithm can be implemented in ladder by masking and shifting four 6-bit characters into a double word register then moving the three bytes into the packed ASCII string. Reconstruction of ASCII characters: Unpacking packed ASCII strings requires flipping some bits in addition to uncompressing the string itself. To unpack a packed ASCII string: 1. Unpack the four, 6-bit ASCII characters. 2.
