In this version, a new I/O type family can be used with ClassicLadder: distributed (remote) inputs/outputs using the modbus protocol.
Two modes are supported: modbus/rtu (serial) or modbus/tcp (ethernet).
Many constructors have theses types of modules in their catalog.
Official site for modbus is : http://www.modbus.org
During the tests, the 2 following models have been successfully used:
-modbus/rtu (serial RS485), see: http://www.ipac.ws/
-modbus/tcp (ethernet, ADAM-6051), see: http://www.advantech.com
If you make tests with other models, do not forget to send me an e-mail or post in the forum, to be able to complete the compatibility list (and if possible, add the detail of the parameters you entered in ClassicLadder).
Bye. Have fun!
