SquarePLC

OK now I want to transmit the RS232 via blue tooth or wireless between the 2 PLC's. I bought the following adapters and some RJ11 to female serial cables but am getting no signal through. The 2 devices are connecting up but there is no data transfer. I tried changing some of the jumpers in the instructions but the language is a bit beyond me. Any suggestions on this or other easy to set up blue tooth/wire less RS232 devices? https://gridconnect.com/bluetooth-to-serial.html Thanks

Thanks for your answers. On my slave end I also had a button controlling MB6 this was stopping the MODBUS force coil from working, got rid of the button now good to go!

I am very green on MODBUS , I am trying to set up a simple force coil command to turn on MB6 in a secondary PLC. (I am using 2 x Vision 1210) . There seems to be communication between the 2 PLC's but I think I have the Slave:Operand Address wrong on the master force coil FB ( I have it as hexi decimal 6) . Any advice would be appreciated.

Hi All, I'm wondering if anyone has used the UniStream to cue videos on a separate television monitor? I am hoping to create a few hot buttons on a screen that start videos on demand not sure if this is possible by using just the PLC or if I would need some type of interface. Any advice would be appreciated. Thanks!
