TROUBLESHOOTING
9.1
CHANNEL ERRORS
The following errors indicate potential hardware or configuration problems. If an error
occurs, a message is displayed for that channel.
9.1.1
COMM ERROR
Comm Error can occur for Modbus or wireless channels. This error indicates the data
was not received. Comm Error can indicate a timeout or an invalid reply from a device.
Check communication settings for the port used as well as the
Data from
menu for that
channel. The ports themselves can be tested from the
Diagnostics
menu.
9.1.2
CONFIG ERROR
Config error can occur for Modbus or wireless channels only. This error indicates that
the Interface selected is configured for something else. For example, if
COM1
is set to
Modbus slave and a channel 1 is set with a
Source
of
Modbus 16bit
and an
Interface
of
COM1
. To correct this, either edit the COM port in
Communication Settings
menu or
edit the channel’s
Interface
in the
Data From
menu.
9.1.3
I/O ERROR
I/O Error indicates a problem communicating with the analog input boards. This error
will affect an entire group of 16 channels at a time, assuming they are all setup for
analog input. Check wiring from the Main I/O Board to the affected Analog Input board.
Verify that the analog input board is setup to for the correct channel group. Only a
single input board in a system can be set to use each channel group. See
I/O Board
Config
in the
Diagnostics
Menu.
