4.2 Process values
All analog and digital inputs and outputs or bus setpoints and actual values can be read and processed by
the PLC or can be set by the PLC (if they are output values. Access to the individual values is by means of
the process values listed below.
For all output values, the output (e.g. digital outputs or PLC setpoint) must be programmed so that the PLC
is the source of the event.
All process data is read in from the PLC by the FI at the start of each cycle and is only written to the
frequency inverter at the end of the program.
The following table lists all of the values which can be directly accessed by the PLC. All other process
values must be accessed via the function blocks MC_Readparameter or MC_WriteParameter.
4.2.1 Inputs and outputs
Here, all process values which describe the I/O interface of the frequency inverter are listed.
