Basic Troubleshooting
Measures to perform
Check the Ethernet cable to see if it is connected correctly.
Check the Ethernet settings to see if they are correct between the
devices.
Check the communications cable to see if it is disconnected.
Check the switching hubs to see if any of them are faulty. (If switching
hubs are used.)
Check to see if the TRIG signal is being correctly input to the Sensor.
Check to see if the most recent NG result is being displayed.
If other devices are connected to the same network as the Sensor, dis-
connect the other devices from the network and check the update
speed.
If the update speed returns to normal, check the specifications of the
disconnected devices and take suitable measures.
If there are power lines running in parallel with the Ethernet cable or if
there are inverters or other sources of noise near the communications
cable, separate the communications cable from them and check the
update speed.
Noise may be adversely affecting the communications response.
Check to see if the logging setting in the Sensor are correct.
If logging to an SD card is not possible, check the available space on the
SD card and check to see if the SD card is write-protected.
Check the error history to see what error has occurred and take suitable
measures.
