COMMUNICATION ALARM AT CHn : GROUP xx
---< ERROR POSITION>--- CHn / GROUPxx
---
<1> Check the I/O device of group
“xx” in channel “n”
– Instantaneous power failure – Unstable power line
<2> Check the I/O Link cable between JD1B of group “xx”
and JD1A of group “xx-1”
– faulty wiring – incomplete contact
<3> The I/O Link device of group
“xx” in channel “n” is faulty.
An I/O Link communication error occurred.
“n” is a channel number (1 to 3).
“xx” is a group number (0 to 15).
“yy” is a internal error code.
This error occurs when the communication with the device of group “xx” in channel “n” is stopped.
The causes are as follows:
– Instantaneous power failure, unstable voltage or unstable power line of the device – Faulty wiring or incomplete
contact of communication cable – Faulty device
Please note that It may not show an accurate group number with some conditions of the problem.
