Hi,
I have a custom slave device that I would like to controll using PLC's COMM1.
A small software that allows me to test the slave from a PC. works perfec.
If I send the same command with the PLC ( ie. Outcomm 1,&H55 )I can see this being received by PC.
In the same time same command is not received by the slave.
So the slave works with the PC, the PLC works with a PC but they are not working between them.
The slave receives the signal thru a Max232.
Any sugestions?. I run out of ideeas
