Hello again dear friends.
We have a couple of machines in our plant that we want to modify.We would need 16 more inputs and a couple of outputs(like 8),and we have all CPU21 from CQM1 series.As i searched trough the manuals we can have only 8 modules(either input or output)i believe,that is actually our configuration.
If i plan to go on CQM1H-CPU21 series,how many modules of in/out can i add? In manual i can see 11 on the rack,or 16 with the expansion module.Is that right or i am mistaken.
I was thinking to keep the same cpu so i do not have to change the programs.Would you think is better to apply for other CPU's?
Thank you!
