CP1L-EM :Reading of stored IP Address

2 posts in this topic

I know there is a way to connect without knowing the IP address, but for some reason I would like to know if it is possible to read the IP address in the PLC memory.

I looked in "A" and "D" and did not found.

In the W516-E1-01 manual, appendix G, there is a mention about internal addresses 173 and 174.

How can we access theses internal addresses?

As far as I know the only way to check the IP address is from the "Settings/Built-in Ethernet" page in CX-Programmer.

A MOVR instruction converts a data address to a PLC memory address in an IR or DR register, but there doesn't seem to be any way to reverse that instruction. MAYBE??? you could use a MOV instruction to load &173 into an IR and get there somehow????
