Jerther Posted August 17, 2015 Report Share Posted August 17, 2015 Hi! We have a Vision 130 PLC connected to a piece of equipment which sends us data through RS232 serial communication. Everything works fine but the PLC stops seeing new data frames for no apparent reason. The only way I've found to get the communication back is to reset the PLC (power cycle). Then it's good to go for anything between 30 seconds and a couple of minutes. Here is a small video showing what's happening in the serial buffer monitor: http://screencast.com/t/Z307fIC6v4n We've hooked up another monitor to the equipment and it never stops sending data frames. The PLC just does not see them until we reset it. Any idea where to look? Thanks!!! Quote Link to comment Share on other sites More sharing options...
