Press Clear to Exit
If the controller is communicating properly with the
building automation system, both numbers will con-
tinue increasing in value. For Modbus protocol, the
read and write numbers should be equal and increas-
ing with every poll. For BACnet, both numbers
should be increasing, but they will not be equal. The
write value will increase even when not connected.
For the Metasys N2 protocol, both numbers should
be increasing but may not be equal. This test feature
is not supported for Lonworks. If both numbers are
not increasing in value, the controller is not commu-
nicating properly. Check the wiring at the terminal
blocks. See section 4.3.10 for more information on
communications setup. Press CLEAR to exit this test.
