Wiring Requirements

Use 

Figure 9

 to determine the maximum wire length allowable when alternative wire gauges are required.

 

 

Setup and Adjustments

Determining the FC Bus Address

The FC Bus address switch sets a unique address for this controller on the FC Bus. You must set the FEU’s device 
address for your field bus application. 

Set consecutive device addresses 4 through 127 for Field Equipment Controllers and other master devices on the 
FC Bus. Use sequential addressing with no gaps in the device address range to ensure best FC Bus performance.

Note:

 Switch 128 on the device address DIP switch block is not used, and should be set to 

Off

.

Table 3

 shows and describes the valid FC Bus and SA Bus devices addresses for FEUs and IOMs on Johnson 

Controls® MS/TP communications bus applications.
