CP 523
Example:
Transferring parameter setting data for parameter block 0
Start address 128 is set on the CP 523.
Set CP parameters as follows:
Parameters for the serial interface (parameter block 0)
2400 baud
Even parity
No BUSY signal
V.24 (RS232C) interface
7 data bits (11-bit character frame)
Handshake OFF

Note:
Restart OB 22 is processed only when the CPU is at RUN before switching from POWER OFF to
POWER ON.
Special features pertaining to parameter setting of "3964(R) mode" in the user program
As in "Transparent" and "Interpretive" mode, you transfer all parameter setting data to the CP
with job number 90XX
in the same way as in the other modes, except that you must transfer a number of additional
parameters for "3964(R) mode". These added parameters are defined in parameter block 7. Since
it is not possible to transfer all required parameters in 8 bytes, the parameter setting of parameter
block 7 is divided into two steps. The job numbers for these steps are 9073
907A
(follow-up job request).
