Serial communication failed – try again.
The serial port seems to be available, but it is not possible to connect to the D485.

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).
•

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
