)
In AC500 the following interface identifier applies:
14 = I/O bus, 11 = COM1 (e.g. CS31 bus), 12 = COM2.
The PNIO diagnosis block does not contain this identifier.

)
With "Device" the following allocation applies:
31 = module itself, 1...10 = expansion module 1...10, ADR = hardware
address (e. g. of the DC551-CS31)
3
)
With "Module" the following allocation applies dependent of the master:
Module error: I/O bus or PNIO: 31 = module itself; COM1/COM2: 1...10 =
expansion 1...10
Channel error: I/O bus or PNIO = module type (1 = AI); COM1/COM2: 1...10
= expansion 1...10

In case of module errors, with channel "31 = Module itself" is output.

Risk of invalid analog input values!
The analog input values may be invalid if the measuring range of the inputs is
exceeded.
Make sure that the analog signal at the connection terminals is always within
the signal range.
