7.1.2 System flags: inputs and outputs
19747
System flags (symbol name) Type Description
INnn BOOL Status on binary input nn
Requirement: input is configured as binary input
(MODE = IN_DIGITAL_H or IN_DIGITAL_L)
TRUE: Voltage on binary input > 70 % of VBBS
FALSE: Voltage on binary input < 30 % of VBBS
or: not configured as binary input
or: wrong configuration
Qxx
xx = 00...15 BOOL Status on binary output xx:
TRUE: output activated
FALSE: output deactivated
LEDnn BOOL Status on LED output nn:
TRUE:LED activated
FALSE:LED deactivated

7.1.3 System flags: system
19748
System flags (symbol name) Type Description
SUPPLY_SWITCH BOOL Bit for switching off the supply latching VBBs.
Separation of VBBs is done before the next PLC cycle starts.
Depending on the charging status of the internal capacitors it
may take some time until the device switches off.
TRUE: Supply of the device via VBBs is active
FALSE: Supply of the device via VBBs is deactivated
TEMPERATURE INT Temperature in the device in [°C]
