23
DB19
DBX24.2
COM2 (status RS-232-C from PLC)
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change 0 → 1
COM2 active
Signal state 0 or
edge change 1 → 0
COM2 inactive
Application
example(s)
The actual status of the RS 232C is sent to the PLC in acknowledgment byte DB19.DBB24.

COM1 active
Signal state 0 or
edge change 1 → 0
COM1 inactive
Application
example(s)
The actual status of the RS 232C is sent to the PLC in acknowledgment byte DB19.DBB24.

DB19
DBX24.4
RS-232-C stop (status RS-232-C from PLC)
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change 0 → 1
RS-232-C stop active
Signal state 0 or
edge change 1 → 0
RS-232-C stop inactive
Application
example(s)
The actual status of the RS 232C is sent to the PLC in acknowledgment byte DB19.DBB24.

DB19
DBX24.5
RS232C external (status RS232C from PLC)
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change 0 → 1
RS-232-C external active
Signal state 0 or
edge change 1 → 0
RS-232-C external inactive
Application
example(s)
The actual status of the RS 232C is sent to the PLC in acknowledgment byte DB19.DBB24.
The bit "RS-232-C external" is delayed until the transfer of the part program to be externally
executed has been started and the selection has been made. Only then is an "NC Start" possible.
