)
With "Module" the following allocation applies depending on the master:
Module error: I/O bus or FBP: 31 = module itself; COM1/COM2: 1...10 =
expansion 1...10
Channel error: I/O bus or FBP = module type (2 = DO); COM1/COM2: 1...10
= expansion 1...10
4
)
In case of module errors, with channel "31 = module itself" is output.
State LEDs
During the power ON procedure, the module initializes automatically. All LEDs (except the
channel LEDs) are ON during this time.

Technical Data
The System Data of AC500 and S500 Ä Chapter 2.6.1 “System Data AC500” on page 1248 are
valid for standard version.
The System Data of AC500-XC Ä Chapter 2.7.1 “System Data AC500-XC” on page 1309 are
valid for the XC version.
Only additional details are therefore documented below.
