Modicon M340 Controllers, Setup Guide

Modicon M340 controllers manage the entire controller station, which consists of analog and discrete I/O modules, counting modules, expert modules, and communication modules. These are distributed across one or more backplanes connected on the local bus. Each backplane must include a power supply module; the main backplane supports the controller. This guide describes the hardware installation of the Modicon M340 controllers and installation of their main accessories.
