There are two steps of error diagnosis:
·
the initial approximate diagnosis by checking the LEDs of the device,
·
the comprehensive diagnosis with the SYCON.net configuration and
diagnosis software via LAN connection.
The following overview describes the error conditions that may be detected
by checking the LEDs (for identification of the LEDs, please refer to section
Positions of the LEDs, connectors and control elements [
}
page 31]).
For information on how to diagnose the netHOST device with
SYCON.net, see Operating Instruction Manual
Configuration of LAN
controlled master devices – netHOST , DOC130402OIxxEN, stored
on the netHOST Solutions DVD in the
Documentation\english
\1.Software\SYCON.net
directory.
