We've a 555-1106 with one remote base and three other PB devices.
This base has a 505-6870 RBC, and three modules / IO cards. I am trying to add a fourth. None are Special Function cards.
I have tried to with PLC in RUN, HALT, with RBC enabled and disabled, all to the same result:
"The number of slave modules exceeds the maximum number of modules for the device."
Not that it should matter, but I am using 505 Workshop software.
Has anyone here an idea or solution?
