Troubleshooting
The following causes are probable. Take the necessary countermeasures as provided
below.
1. The PCMCIA card may not be recognized correctly.
Select Control Panel, System, and Device Manager, and check that
3G8E2-DRM21-V1 or 5136-DNP-PCM(n) (where n is the PCMCIA slot
number) is in the SST devices. Select Property and Resource and check
that the resource settings are made properly in an unallocated area.
If the PCMCIA Card is not recognized correctly, dismount and mount the
Card again. If the Card is still not recognized, install the PCMCIA Card
again.
2. The above resource set value and Card driver set value may be different
to each other. Set the correct value in the 3G8xx-DRM21 Configuration
Software.
The following causes are probable. Take the necessary countermeasures as provided
below.
1. The master may have a configuration error or comparison error.
If the master has a configuration error or comparison error, data cannot
be read from the slave correctly.
Turn OFF the master, create and write parameters to the Master, and ex-
ecute List Devices.
2. The network may be unstable.
Proper communications will not be available if the network is unstable due
to noise, line disconnection, improper contact loose connectors, or loose
connector screws. As a result, all the devices may not be displayed.
Check the above items.
3. The network load may be too high.
The network load will be excessively high in the following cases. As a re-
sult, the Configurator may have a timeout error and all the devices may
not be displayed.
• More than one master is connected to the network.
• High-density slaves are connected to the network.
