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 P485.

•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 Modbus network. If the P485 reports very many re-transmissions, 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 P485, 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 P485, and should only be used when necessary.
