Control commands
The control commands FREEZE, SYNC and CLEAR_DATA are
supported by the CPX terminal in accordance with EN 50170
(DIN 19245). The method of accessing these commands de-
pends on the controller used. Please refer here to the docu-
mentation for your field bus module.
Information on DPV1 commands can be found in section A.3
in Appendix A.
Caution
In the following cases, the FREEZE or SYNC mode will be
reset automatically:
– when the CPX terminal is switched on or off
– when the field bus module is stopped.
The FREEZE mode will also be reset automatically in the
following case:
– when the bus connection to the CPX terminal is inter-
rupted (response monitoring active).
FREEZE
With this function all the inputs of the CPX terminal can be
"frozen." The CPX terminal then sends a constant input image
of all the inputs to the master. The following FREEZE com-
mand causes the input image to be updated. The updated
input image is then sent constantly to the master.
Return to normal operation: UNFREEZE command.
