Dear nandgate, Are you using library block or have you made your own logic for modbus communication? If you are using library block then I would request you to please check parity & stop bits for the Com of PC & you have defined in your program. Both should be the same. |

We are using library files and we have tried odd, even and no parity. And in all configurations we got the message as request timed out. |

Dear nandgate, I have checked your backup & corrected it. Kindly check that backup & revert back to me. There was only problem of SM0.0 used for MODBUS_INIT. This block should be called for first scan only. AttachmentSlave Modbus.zip (260 Downloads) |
