B R # 11: C om m u n icat io n Tim e- ou t ( ms)
Explanations:
For setting up the communication time-out. Default = 5,000ms. For example, if you wish to set up the
communication time-out to 7 seconds manually, write 7000 to BR#11. Range: 5 ~ 65,535.
BR# 12: C ommu n icat io n De la y Time ( ms)
Explanations:
For setting up the minimum interval time between every Modbus command. Default = 0ms. For example, if you
wish to set up the communication delay time to 100ms manually, write 100 into BR#12. Range: 0 ~ 65,535.
BR# 13: TCP Co nn ectio n Id le Time ( s)
Explanations:
For setting up the TCP connection idle time. Default = 30 seconds. For example, if you wish to set up the idle time
to 7 seconds manually, write 7 into BR#13. Range: 5 ~ 65,535.

Check if the power supply of the module works normally.
1. Check if the settings of smart PLC are incorrect.
2. Re-power RTU-EN01. If the error still exists, try step 3.
3. Reset RTU-EN01. If the error still exists, send the module back to
the manufacturer for repair.
Check if RTU-EN01 is connected normally to the network.
Check if the number of connected modules exceeds the maximum.
Check if the RS-485 communication format is correct.
1. DHCP request failure.
2. IP setting error.
3. MASK setting error.
4. Gateway does not exist in the same subnet.
5. Returning to default setting.
Check if the configuration of the right-side module has been modified. If
the error still exists, check if the number of I/O points exceeds the
maximum and whether the there are more than 8 analog I/O modules
connected.
1. Check if RTU-EN01 and RS-485 is connected normally.
2. Check if the series transmission speed is consistent with that of other
nodes on the network.
