Validity:
The validity of an analog or maths channel is returned.
The relayed value of the function is 0 in the event of:
• Open circuit
• Invalid measured value
• Sensor error
• Input signal too high/low
• Error value
The relayed value of the function is 1 in the event of:
Measured value OK, even if the limit value is breached

Duration
Not all signal types are available for each input type. These depend on the respective
device options.
Channel number:
Analog channel 1 = 1, analog channel 2 = 2, digital channel 1 = 1, …
Examples:
DI(2;4)
State of digital channel 4
AI(1;1)
Instantaneous value of analog channel 1

Status of a limit value:
LMT (type, limit number)
Type
Description
1
"Instantaneous value": Currently set limit value
2
"State": The function returns the status of a limit value
The result is 1 if the limit value is violated.
The result is 0 if
• The limit value is not violated
• The limit value is not switched on
• Limits monitoring is switched off (e.g. per control input)
Examples:
LMT (1;1)
Instantaneous value of limit value 1
LMT (2;3)
State of limit value 3
