Settings in the CPU by means of STEP 7
Use STEP 7 to configure your controller as follows.
●
Slot 1: Power supply
●
Slot 2: CPU
●
Slot 4: CP 341, start address 256
●
Slot 5: CP 341, start address 272
Settings on the CP 341
You cannot make any hardware settings on the CP 341.
Use STEP 7 to configure all relevant data, including the parameters for the CP 341 with the
CP 341: Point-to-Point Communication, Parameter Assignment parameter assignment and
upload them to the CPU.
You can run the "CP341 protocol 3964" program example without making changes in the
application program with:
●
3964(R) Procedure
●
ASCII driver with "on expiry of character delay time" end criterion
●
ASCII driver with "on receipt of fixed message frame length" end criterion.
For the ASCII driver with the "on receipt of the end character(s)" end criterion, you must also
program the end codes.
The functions for reading and controlling RS 232C secondary signals can only be executed
with the ASCII driver. Controlling is only possible if in the "Transmission" tab the "Automatic
use of V24 Signals" parameter is not selected.
