4.5.1 Defining the operating mode with CCON
Operating mode Description
Record select operating mode
 Record select mode
(OPM1 = 0; OPM2 = 0)
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.
Direct operating mode
 Direct mode
(OPM1 = 1; OPM2 = 0)
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 operating
mode
(OPM1 = 0; OPM2 = 1)
Commissioning functions (e.g. identification) can be executed and
parameters read or written. Positioning jobs are not possible.
Parametrising operating
mode
(OPM1 = 1; OPM2 = 1)
A parameter is transferred into the I/O data according to the FPC
protocol. Positioning jobs are not possible.
