9.4 Line Test (Connection Status Check)
After connecting all of the units with CC-Link dedicated cables, verify that they are correctly connected and
that data linking can be performed with remote stations and intelligent device stations.
Check whether data link can be normally executed with all (16) remote stations and intelligent device stations.
Line test 2 checks the status of communication with specific remote stations and intelligent device stations.
Neither line test 1 nor line test 2 requires parameter settings.
Point
Execute line test 2 when an error occurs in line test 1.
Accordingly, when no error is detected in the line test 1, there is no necessity to execute line test 2.
9.4.1 Line test 1
Check whether data link can be normally executed with all (16) remote stations and intelligent device stations.
Line test 1 does not requires parameter settings.
• The following sequence outlines the line test 1 execution procedure:
1) Set the station number setting switches of the FX
3U-16CCL-M to "× 10: 0" and "× 1: 0".
2) Set the transmission rate setting switch of the FX
3U-16CCL-M to "5" to "9" (line test mode).
Caution
Set the same transmission speed to all of the FX
3U-16CCL-M and remote stations/intelligent device stations.
3) Turn off the power of the PLC and the FX
3U-16CCL-M, then turn it on again.
Approximately 4 seconds later, line test 1 starts.
4) Confirm the line test results using the LEDs of the FX
3U-16CCL-M.
[When the line test is complete]
- The L RUN LED turns ON
→ Communication with or more stations is normal.
- Line test 1 results are stored in SW00B4 (BFM#6B4H).
However, since line test 1 is performed for 16 stations, disregard the bit (s) for any unconnected
stations.
[When the test is incomplete (all stations are abnormal)]
- The ERR. LED flickers
→ All stations are faulty or cable is broken.
Line test 1 results (error codes) are stored in SW00B8 (BFM#6B84H).
- ON LED: None
→ Test cannot start (due to abnormality in hardware or power OFF in all stations).
