5.1 CompactLogix

In this example, the system consists of a 1769-L32E (Compact Logix 5332E Controller) processor and a 1769-IT6

Thermocouple Input Module residing in slot #1. The Compact Logix IP address is 192.168.1.95. The 1769-IT6 module’s

six input channels are sent to the DX Advanced Communication Channels C01 thru C06. The 1769-IT6’s channels are

configured for ―Engineering Units‖ which will result in an integer value with an implied decimal point (i.e. 66.8 = 668). The

DX Advanced’s IP address is 192.168.001.100, The DX Advanced’s Measurement Channels 001 thru 010 are being read
and stored in 10 words starting with an Array Tag named ―DX_Advanced_Measurement Channels‖, configured for REAL
format. Two ―MESSAGE‖ tags were created for use with the MSG instructions, ―DX_Advanced_Data_Read‖ and
―DX_Advanced_Data_Write‖.

In the ladder example below, the ―Write‖ and ―Read‖ MSG instruction’s Message Control Tag’s Enable bit (.EN) is used to

continuously toggle the instruction. If another data transmission interval is required, configure the rung appropriately.
