8-8 Communicating with Devices on a DeviceNet Link

Module Command Array

The module command array is the primary control interface between your

control program and the module. In RSLogix 5000 software, the

CommandRegister tag structure is as follows:

ahw0953.tif

Output Word Bit Description Behavior

0 0 Run This bit controls when the module scans its mapped slave devices. When

set (1), the scanner will process I/O data as defined by its scanlist. To

actually scan the network the Fault and Disable Network command bits

must be clear (0).

1 Fault When set, the scanner’s I/O mode will be Halt; messaging will still operate.

The fault bit is primarily used to artificially set the slave devices into a fault

state due to some event or condition within the control program.

2 Disable Network When set, the scanner is functionally removed from the network.

3 HaltScanner When set, the scanner stops scanning its mapped slave devices.

4 Reset Restarts access to the DeviceNet network.
