What’s your name?
I’m CPU 315-PN/DP.
Can us two lonely souls someday become one?

Hello.
I’m VAMP 210. What’s yours?
OK, whatever…
You have to ”do” me first…
Configure a standardised MODBUS/TCP communication prototol for me.

ÎÎ Note! If you want to change the Address of Alive indicator from DB121.DBW20 to DB121.DBW32 Note! If you want to change the Address of Alive indicator from DB121.DBW20 to DB121.DBW32 you have to use DB_HOLD_ADD in FB170 MBTCP_READ_WRITE. This is how it works… you have to use DB_HOLD_ADD in FB170 MBTCP_READ_WRITE. This is how it works…
Lets first use same values in START_ADDRESS and DB_HOLD_ADD (16#07C7 à 1991). Lets first use same values in START_ADDRESS and DB_HOLD_ADD (16#07C7 1991).

Remember,that thatwe wearen’t aren’t now actually reading addresses 401987 … 401990, we have set Remember, now actually reading addresses 401987 … 401990, because because we have set START_ADDR 1991 in DB22. START_ADDR to to 1991 in DB22.
