.Common Problems and Solutions
Device cannot connect to PLC or computer
Possible reason:
1. The computer has multiple COM ports, and the selected port is incorrect.
2. The device address is wrong, or there are devices with duplicate addresses (the factory default is all 1).
3. Baud rate, check mode, data bit, stop bit error.
4. The host"s polling interval and waiting time for answering are too short, and both need to be set above 200ms.
5. The 485 bus is disconnected, or the A and B lines are reversed.
6. If there are too many devices or the wiring is too long, power should be supplied nearby, add a 485 enhancer, and add 120 Ohm terminal resistance.
7. The USB to 485 driver is not installed or damaged.
8. The equipment is damaged.
