Ladder programming & modbus

We have 2 Logic controllers from schneider electronics.

See http://uk.rs-online.com/web/p/logic-modules/0548050/

These controllers are programmed with a method called 'ladder programming'.

See https://en.wikipedia.org/wiki/Ladder_logic

Also, those controllers are able to be monitored and controlled over modbus.

See https://en.wikipedia.org/wiki/Modbus

We will try to get them working and learn the basics of ladder programming and modbus.
