Let’s check the MIO configuration to work with input modules. Check that the following registers have values.
Address (base address for first WD-14 module) - value
11000 - 0xffff
11001 - 0x0000
11002 - 0xffff
11003 - 0x0000
11004 - 0x0000
11005 - 0x4444
10999 - 0x0001
For second module addresses increased on 1000:
12000 - 0xffff
12001 - 0x0000
12002 - 0xffff
12003 - 0x0000
12004 - 0x0000
12005 - 0x4444
11999 - 0x0001
For third module addreses 13000, 13001…
