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.

Cam Posted September 11, 2017 Report Share Posted September 11, 2017 Is it possible to have two serial ports in the V130. It will require an extra card to be inserted into the PLC.V100-17-RS4 or RS4X. Quote Link to comment Share on other sites More sharing options...
hotwires Posted September 12, 2017 Report Share Posted September 12, 2017 (edited) On a V430 two serial ports. Port two can have a second (optional) serial board installed. V1210 has two included serial ports and option for a third. Not sure about others. Specs would reveal. I have used the two included serial ports on a V1210 simultaneously one to a PC and second as a MODBUS master. Please note that the mini USB port (when actively connected) takes over the primary serial port. A bit of an inconvience when wanting to be on online mode and have serial port also working out RJ11 jack. Sounds like two on the V130 also.

sanyc Posted September 14, 2017 Author Report Share Posted September 14, 2017 Thanks for your replies. Also samba has an integrated RS232 and I can expand it with V100-17-RS4. Can I order the PLC to come with the integrated port as an RS485 instead of RS232? Quote Link to comment Share on other sites More sharing options...
Cam Posted September 14, 2017 Report Share Posted September 14, 2017 the 3.5" samba has a native rs232 port it doesn't have RS485 though. You would have to add the v100-17-RS4 to get that. The SM43 and SM70. Do not have a native com port so you would have to add the RS4 in order to have either RS232 Or RS485. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted September 14, 2017 MVP 2023 Report Share Posted September 14, 2017 I feel the need to point out that the 120 series has 2 native comm ports which will do this job without trouble. They also have inbuilt Canbus/Unican which lets live PC communication happen concurrently if needed, by going via another 120, which can be disconnected once the project is complete. Grist for the thinking mill. Think of it as having a spare for the job! cheers, Aus Quote Link to comment Share on other sites More sharing options...
sanyc Posted September 17, 2017 Author Report Share Posted September 17, 2017 V120 sounds a nice option, with configurable ports for either RS232 or RS485 Quote Link to comment Share on other sites More sharing options...
