my previous post was about which addressing NJ/CJ supports.

i m asking here that will the symbolic address over ethernet/Ip with NJ/CJ omron plcs support CpU status and CPU type operands?

I don't really understand what did you mean by CPU Type Operands, however for CPU Status, it will basically consume a small bytes of the symbol (2 bytes at most IIRC).

In case NJ will receive other PLCs status, one way to do it is to create a symbol with data type of BYTE Array, then separate the 2 first index as CPU Status.
Another way is to create a STRUCT which contains two members, CPU Status and the Data itself. Of course you need to match the size of each member.

In case CJ will receive PLC status from NJ, there is no need to map the status as a symbol in NJ since it will be padded automatically. You just need to separate each byte part in CJ later on to differentiate CPU Status and Data.
