B R # 11: C om m u n icat io n Tim e- ou t ( ms)
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)
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)
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.

How to correct
network.
Check if the number of client connections exceeds the
maximum. (8 EtherNet/IP or 16 Modbus TCP
connections)
Check if the RS-485 communication format is correct.
1. DHCP request failure.
2. IP address invalid.
3. Subnet mask invalid.
4. Gateway does not exist in the same subnet.
5. Returning to default setting.
Check if the configuration of the extension 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/specialty
I/O modules connected.
1. Check if ELC-CAENET and RS-485 are properly
connected.
2. Check if the RS-485 transmission speed is
consistent with that of other nodes on the serial
network.
