the PCS.

Data transmission PCS-PCS 830 Data traffic between the PCS and the programmable controller is effected

in data packets. Each data packet is assigned a checksum. The package

content is checked for possible errors by the PCS 830. Each packet

consists of a minimum of one sub-packet which performs a clearly defined

task. The tasks to be integrated in a packet are determined by the PCS

based on the pro-grammable controller scan-time, the baud rate and the

priority of each task. Each of this tasks is assigned a specific start priority.

Priority management assures that no task is lost. The indicated packet

lengths refer to words, including header.
