Report Input issues in Vision & Samba PLC + HMI Controllers & VisiLogic Software Posted June 17 Hi, 1)Please check HW-config in Visilogic 2) From manual ---- Connecting RG Pins. For correct operation of digital and analog inputs and for EMIimmunity, connect the RG pin of all the expansion modules containing RG signals to the adapter module 0V signal. The overall length of the wire connecting the RG pins to the adapter 0V signal must be less than 3 meters. Connect the RG pins inseries (daisy chain). To facilitate this, use both the RG pins. 3) From manual----Do not connect the neutral or line signal of the 110/220VAC to the device’s 0V pin. 4) Use another power supply. If no success - please build only one module configuration with EX-A2X and check module separately on table.
