sanyc Posted September 11, 2017 Report Share Posted September 11, 2017 Hi, How many serial connections can I have on a vision series PLC? For example I want to attach a modem on a V130 in order to remotely send commands and at the same time I want to connect an LED screen with an RS232 connection in order for the PLC to send commands and write on the screen.
