Error processing
The ramp end value is specified by the active setpoint value (output signal of setpoint value
function). If this signal is "out of range", this affects the output signal of the ramp function. The
following circumstances may arise:
If the active setpoint value has returned to a valid value, the ramp function is continued with the
last ramp value that was valid before the error occurred.
If during such an error event, the ramp function is started, stopped, aborted, or switched off, a
differentiation must be made between the cases below:
Tolerance band monitoring is not active during an error event.
Active setpoint value (output signal of set-
point value function) Output signal of ramp function
Underrange Error value 1.0E+37
Overrange Error value 2.0E+37
No value Error value 3.0E+37
Valid value Current ramp value
Action Output signal of ramp function
Start When the error event is over, the ramp function starts and the current ramp
value is issued.
Stop This action is not possible in the event of an error.
Abort When the error event is over, the ramp start value is issued.
Switch-off When the error event is over, the ramp end value is issued.
