Remarks:
1
)
In AC500, the following interface identifier applies:
"-" = Diagnosis via bus-specific function blocks; 0 ... 4 or 10 = position of the
communication module;14 = I/O bus; 31 = module itself
The identifier is not contained in the CI542-DP diagnosis block.
2
)
With "Device" the following allocation applies: 31 = module itself, 1..10 =
expansion module
3
)
With "Module" the following allocation applies depending on the master:
Module error: 31 = module itself
Channel error: module type (1 = AI, 2 = DO, 3 = AO)

)
This message appears if external voltages at one or more terminals DC0..DC7
or DO0..DO7 cause other digital outputs to be supplied by that voltage (voltage
Chapter 1.7.2.3.3 “Connections” on page 660
All outputs of the digital output groups will be turned off for 5 seconds. The
diagnosis message appears for the whole output group.
