ABB AC500 PLC - Small Overview of the Addressing Possibilities

If the bus module is configured as a Fast Counter module and '0 - no Counter'
in Automation Builder is selected the channel ERR LEDs stays on and the
module does not start up. The address was adjusted with '71'.
Only the '0- no Counter' mode does not operate. If any other counter is selected
e.g. '1-1 Up counter' the module starts up and can be utilized.
Small Overview of the Addressing Possibilities
Configuration example with 32 analog inputs with or without 32 analog outputs (Fast Counter
not used) = 5 bus addresses by the bus module

address
If the number of analog outputs is less than the number of analog inputs, no additional address
is necessary. Change the type from "analog in" to "analog I/O".
● 30 bus addresses used, 1 bus address free
● 192 analog inputs (+ 192 analog outputs)
● 48DI / 96DC (144 DI / 96 DO for CS31 and user program)
● Switch address incremented to avoid control overlap.
In CPU table module switch address n will be seen as (idem for AC500 or old CPU):
● Address n, type digital I/O, 8 DI/16 DC
● Address n, type analog I or I/O, 8 AI (+ 8 AO)
● Address n + bit 8/15=1, type analog I or I/O, 8 AI (+ 8 AO)
● Address n+1, type analog I or I/O, 8 AI (+ 8 AO)
● Address n+1 + bit 8/15=1, type analog I or I/O, 8 AI (+ 8 AO)
