Hi,
I want to connect 2 Twido ldmda20drt PLCs to a Magelis GT5330 Hmi through Modbus. Magelis is the master controller. Twidos have Rs-485 port. Magelis has rs-485 port on Com2. They are all schneider-electric products.
I use 3 rs-485 cables and a hub to connect the devices.
However there are some troubleshootings with the configuration.
In the magelis settings, i create a modbus master driver and in the driver settings i create 2 slaves Twido1 and Twido2. If i designate slave addresses as Twido1=1 and Twido2=2,6,9 or sthg else, only Twido1's controllers work on a Twido device no matter which Twido device i am using or its own address. In other words, Magelis doesn't differentiate between Twidos and their addresses. It communicates with the twidos if the slave equipment address is configured as 1 only in its own settings.
Do you know how to overcome the problem and make Magelis differentiate and communicate with Twidos according to their own addresses?
Any help appreciated.
