Hi community, i need help .... I want to connect my HMI GOT 1455 to a PLC OMRON CP2MC by RS-232, but i cant do it.
I'm using the following connection:
HMI GOT1455 - PLC CPM2C (Interfaz CS1W-CN118)
2 (RX) - 2 (TX)
3 (TX) - 3 (RX)
5 (SG) - 9 (SG)
- 4 (RTS)
- 5 (CTS)
* PIN 4 (RTS) IS CONNECTED WITH PIN 5 (CTS)
In the HMI I configurated driver OMRON SYSMAC, CHANNEL 2 RS-232, TRANSMISSION SPEED 19.200, DATA BIT 7, STOP BIT 2, PARITY EVEN.
But with all of that I can't connect both devices.
In the PLC i can see the led COMM blinking, so it should have communication, but the HMI show me "Communication error. Refer to System Alarm in Utility Menu"
