Hello everyone,
I have a copy of a program with very few named tags and no comments, which is typical. I have been trying to find out which memory is mapped to the PROFIBUS master PRM21 and can't seem to figure it out. I will eventually plug into the module with CX-PROFIBUS and will be able to see for myself but for the time I want to figure them out.
The Module is in slot 5 and the unit number is 0.
According to the manual PRM21 is considered a special I/O unit and because it has unit number 0 it allocated IR100-109 and sure enough in the program 100.0 is used to turn the module on and that's the only bit used of IR memory.
There are four Beckhoff PROFIBUS couplers with 16 out each.
What other memory can be used to control those outputs?
DM memory (thought maybe bit masking) for unit number would be
DM1000-1099 which is not being used.
Thanks
