3 MANAGING A NETWORK OF MULTIPLE CONTROLLERS

The pLAN network is the name of the physical network that links controllers to remote HMI terminals.
pLAN = personal Local Area Network
The connection of the controllers via the pLAN network allows the datapoints of one controller to be exchanged for another,
following the logic set out by the program, i.e. the direction that these datapoints must follow and that from which they come. As a
consequence, they are not programmed by the user, who must only carry out the electrical connection.

3.1.1 Connecting controllers to the pLAN
The electrical connection between the controllers under the pLAN network (RS485) is carried out using an AWG20/22 shielded
cable composed of a twisted pair and a shield. The cards must be connected in parallel using the J11 connector.
The first and last controller must be no more than 500m apart.
3.1.2 Connecting a remote screen or screens to the pLAN
A remote user terminal can be connected to each controller on the pLAN network (RS485) using two cards (CIAT code: 7122917)
and one shielded cable consisting of three AWG24 twisted pairs and a shield.
The shielded cable must be no longer than 200m.
