CP 523 Communications Mode

Example: Transferring parameter setting data for parameter block 7

Start address 128 is set on the CP 523. The module is to be operated in Interpretive mode. The

message frames to be transmitted have different lengths; the end of the message frame is

therefore signalled with 0D0D

(0D0D

=two carriage returns). The character delay time may be

300 ms (300 ms=001E

* 5.2

** FB 99 waits until the CP 523 can accept job requests ( 4.1)
