Using the Test Program

After an overall reset of the PLC, the whole file for the test program can be loaded in the RAM
of the PLC.
Following this, messages T-NR 0 to 14 in DB 162, T-NR 15 in DB 163 and T-NR 30 to 42 in DB
164 must be assigned the required values for variables and parameters. If controlled channels
are not being used, the value zero must be entered for the setpoint in DW n + 0. The required
controller type (2-step/3-step controller) must also be selected in control byte 1
(DL n + 4).
If all the messages above have had values assigned, a cold restart can be performed. The LED
"R" lights up at the top left on the front panel to signal that the module has been assigned
parameters.
The individual functions can now be activated via inputs I 4.0 to I 5.7 and I 7.5.
The required type of parameter assignment is selected at input I 7.0. If a parameter assignment
error occurs during the execution of the test program, the error number remains set at the
output even after the error has been corrected until it is cleared via input I 7.7.
If, during the processing of FB 162, a parameter assignment error occurs with an error number
between 1 to 8, 17 or 23 to 26, a cold restart must be performed after the error has been
corrected.
