Jelmer Posted August 9, 2017 Report Share Posted August 9, 2017 Hello, For a project im working on I need to motitor serval energy sources and control multiple relays. I would like to use the Samba 4.3" PLC for giving a nice interface to the system. The problem is that I have over 30 outpust I need to control. I've found a modbus RTU (RS485) energy meter who measures the voltage and current. Also found a modbus RTU (RS485) digital output module with 16 outputs. Is it possible to use the Samba 4.3" PLC with V100-17-RS4 module to communicate over modbus with the IO modules and energy meters? Best Regards, Jelmer Link to comment Share on other sites More sharing options...
Cam Posted August 9, 2017 Report Share Posted August 9, 2017 Hi Jelmer, It should be possible, another option would be to look at the V430 which is expandable so you wouldn't need the output modules. You'd only have to communicate with the energy meter. 1 Link to comment Share on other sites More sharing options...
