I m a beginer in S5. have some S5 hardware - training unit with 2 plc racks and extention rack EU902 connected to first plc rack with IM304-IM614 link I can easely read input states of DI (DE430) cards and write set outputs of DO (DA451) cards, directly inserted in PLC CPU948R rack using Step5. Problem: I can`t read/write I/O states from/to modules inserted into extention rack (FUM210,FUM230,FUM232) using I and Q statements. So the questions? How to work with those modules , inserted in extention rack using Step 5 or s5 for win? Do i need to configure link PLC - IM304 - IM614- FUMXXX? Do i need to configure FUMXXX position in the rack? any info ? commands ? code exaples?
