Connecting panels to a network
The I/O board contains four terminals (+A2, -A2, +Α1 and –Α1 ). These terminals are used to inter-connect the panels in
installation where we want to install a network. The network can contain up to 32 panels.
Figure 3-12
Connecting panels to a network
The maximum distance between 2 panels must not exceed 400m. If it is required to exceed this distance then an A-485 which
is a RS-485 protocol line amplifier must be used.
In each connection a resistance 120Ω must be placed as figure 3-11 shows
The shield of the cables must be connected to the chassis of the panel.
First of all, all subpanels must be programmed. The automatic setup of the network from the master panel take place after.
