Problem during configuration Upload / Download.
The Config Line “LED” turns red in ACM.
• Serial communication failed. Try again
The serial port seems to be available, but it is not possible
to connect to the gateway
• The serial port may be in use by another application.
Exit ACM and close all other applications including the
ones in the system tray.
Try again
• Select another serial port
Try again
Poor performance • Right click “sub-network” in the Navigation window and
select “sub-network Status” to see status / diagnostic
information about the sub-network.
If the gateway reports very many retransmissions, check
your cabling and/or try a lower baud rate setting for the
sub-network (if possible).
• Is the Subnet Monitor in ACM active?
The sub-network monitor has a negative influence on the
overall performance of the gateway, and should only be
used when necessary.
• Is the Node Monitor in ACM active?
The node monitor has a negative influence on the overall
performance of the gateway, and should only be used
when necessary.
No sub-network functionality • Use the “Data logger”-functionality to record the serial
data communication on the sub-network.
• If no data is being transmitted, check the configuration in
ACM.
• If no data is received, check the sub-network cables. Also
verify that the transmitted data is correct.
