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).

136

When now opening DB121 we see that the Alive indicator is written to DB121.DBW20. When now opening DB121 we see that the Alive indicator is written to DB121.DBW20.

Now whenwe wewant wanttotochange change address of Alive indicator from DB121.DBW20 to DB121.DBW32, we Now when thethe address of Alive indicator from DB121.DBW20 to DB121.DBW32, have to change the 16#07C1 (1985). we have to change thevalue valueofofDB_HOLD_ADD DB_HOLD_ADD toto16#07C1 (1985).


137
