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.
Corresponding to .... Applies to HMI Embedded

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.
Corresponding to .... Applies to HMI Embedded
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.
