Counter function
DPOT
I1
I2
O
I3
The digitally controlled ramp function increments or decrements the output O
according to control inputs I1 and I2. The input I1 ramps the output to positive
direction and I2 to negative direction. If both inputs are active, nothing happens. The
step is defined by the input I3.
Input I1: Count up
Input I2: Count down
Input I3: Ramp step to positive/negative direction (step/sec).
Note: The internal calculation uses 48 bits accuracy to avoid offset errors.
Input I1 and I2: Boolean values
Input I3: 24 bit integer value (23 bits + sign)
Output (O): 24 bit integer value (23 bits + sign)
Event function
EVENT
I1
I2
I3
Input I1 triggers the event. I2 selects the parameter index from which the event
message (text string) is read. I3 selects the type of the event (warning or fault).
I1 I2 I3 Cause
0->1 block activates the event
0 block deactivates the event
I2 contents of the event message
0 type of event: warning
1 type of event: fault
2 type of event: event
Input I1, I3: 24 bit integer values (23 bits + sign)
Input I2: String (compulsory)
