You can set its parameters as follows:
Parameters for the serial interface (parameter block 0)

• Even parity
• No BUSYsignal
• RS-232-C (V.24) interface
• 7 data bits (11-bit character frame)

** The program waits at FB 99 until the CP 523 can accept job request ( 4.1)
Note:
Restart organization block OB 22 is only processed if the CPU is in RUN mode before you switch
from "POWER OFF" to "POWER ON".
Note:
The status byte can be scanned approx. 30 ms after the request was issued in order to check
whether correct parameter setting data was transferred (X4 is returned to indicate errored
values ( 7.4.1)).
