Hello, I have a system of the CPU 1513-1 PN and CM PtP RS422 / 485 BA. Send_P2P I use to send data to the slave, but the data is not sent to the CM module output (TX led does not light up and listen to the program (com sniffer) data "does not see". Why Send_P2P does not work? TIA Portal V13 SP1 protocol: freeport (ascii) p.s. translated by google) AttachmentCM_test.zip (1460 Downloads) |

Maybe somebody has an example of the implementation of the master communication with the slave device on the ascii protocol (freeport). I will be very grateful. |
