Is the Modbus TCP driver compatible with the Modicon Premium P57 5634?
I am not familiar with the Modicon Premium P57 5634, but if it is not listed then you typically want to configure a Modbus TCP/IP device as probably a STAT_PLC. This statically defines the sizes of the memory for the device. One thing you need to be careful of is if this device actually has any invalid memory locations that may cause a cached/grouped read across the invalid locations. For example if you have a registers 40001 to 40020 that are valid but 40021 to 40050 are invalid, and 40051 and 40060 are valid, you need to be sure you don’t accidentally initiate a grouped read across this invalid memory location. This can be difficult since CIMPLICITY automatically groups the reads for you. There is further documentation about the use of the STAT_PLC device in the help files. I hope this helps.
