P3F - Pakscan Master Station Technical Manual

20 of 82

Publication S703E V1.1

Issue 06/09

The recommended highway organisation is:

Use two main data highway bus’s, each of which connects to all the master stations.

The master is left with a Static DHCP port setting.

The master station can serve up to 10 simultaneous host connections.

With this arrangement either PLC port can always communicate with the master station and the
devices on the loop. Heartbeat data requests on the second highway will always be acknowledged
with a response.
