I would need advice in design which we are currently making in Step 5.
Control system is based on Control modules which have defined structure.
However customer requested only one DB due to parametrization with HMI.
If there is only one DB all control modules have to be stored there.
In ladder logic We need to find a way how to use some pointer for adressing Control modules in that DB. Like Control module CM01 Adress 200 and CM02 adress 300.
So far we are not able to do it and could be better if someone has used this idea already. It would really save us some time.
Has anyone experienced same problem and is willing to share the way out?
Thanks,
