2–8 D485 MODBUS TO DEVICENET CONVERTER – USER GUIDE
INSTALLATION
Troubleshooting
DESCRIPTION Problem during configuration upload/download. The Config Line LED turns red.
• Serial communication failed – try again.
The serial port seems to be available, but it is not possible to connect to the D485.
• The serial port may be in use by another application. Exit EnerVista P485/D485 Setup
and close all other applications including the ones in the system tray and try again.
• Select another serial port and try again.
Poor performance.
• Right click ‘Modbus Network’ in the Navigation window and select ‘Modbus Network
Status’ to see status/diagnostic information about the sub network. If the D485
reports very many retransmissions, check your cabling and/or try a lower baud rate
setting for the sub network (if possible).
• Is the Modbus Network Monitor in EnerVista P485/D485 Setup active? The Modbus
network monitor has a negative influence on the overall performance of the D485,
and should only be used when necessary.
• Is the Node Monitor in EnerVista P485/D485 Setup active? The node monitor has a
negative influence on the overall performance of the D485, and should only be used
when necessary.
