Example for forcing of outputs
In the following, the output channels are forced in a CPX
4−output module (Fig. 2/3, module no. 3 ). In steps 1
the forcing function is first released for the CPX terminal.
1. Read out the currently set system parameters via slot 1
index 17.
2. Release the Force mode" system parameter: Set byte 2
bit 2 to 1". (See CPX system manual Tab. B/6 System
parameter: Force mode".)
3. Write the system parameters changed in step 2 via slot 1
index 17.
This releases the Force function for the entire CPX terminal.
Since slot number = module number + 100 (see above),
slot 103 should be used for module no. 3 in the following
4. For the Force State outputs" module parameter for
channels 0 3, via slot 103 set index 28 to 0F
(see Tab. A/11)
5. For the Force Mode outputs" module parameter for
channels 0 3, via slot 103 set index 27 to 0F
(see Tab. A/11)
This sets the outputs 0
