Description
The PLC selects a record from a record list stored in the CMAX.
A record contains all the parameters which are specified for a posi
tioning job. The record number is transferred to the cyclical I/O data
as the setpoint or actual value.
The positioning job is transferred directly into the cyclical I/O data.
The most important setpoint values (position, speed, force) are
transferred here. Supplementary parameters (e.g. acceleration) are
defined via parameterisation.
Commissioning functions (e.g. identification) can be executed and
parameters read or written. Positioning jobs are not possible.
A parameter is transferred into the I/O data according to the FPC
protocol. Positioning jobs are not possible.
All the statuses which must be available in all operating
modes are controlled with control byte 1 (CCON).
