Det-Tronics Mac - w/Supercard - Manual (Page 55)

The Point Display screens allow the operator to monitor gateway opera-
tions and perform certain control functions. The point display can also be
entered by means of the “GetGWpointDisply” XCMD’s.
1. Select the gateway of interest from the Point Configuration screen
list box and then select the “P.Display” button. When the gateway
point display appears, a field in the upper right corner of the dis-
play will show the gateway identifier (A, B, C or D) followed by the
gateways’ point number (1 through 4).
Left or Right MIP Fault The gateway has two LON communication
ports, which are identified as the left and
right MIP. If a problem occurs in either of
these hardware components, the appropri-
ate indicator will turn red.
Gateway Fault This indicator shows that an internal diag-
nostic has detected a problem with the
gateway hardware.
Slave PLC When the gateway is configured to act as
a Modbus master, feeding information to a
PLC or other Modbus Slave device, and
the communication link has timed out, this
indicator will turn red.
LON Master This indicator lights when it is the “Master”
gateway. There can be up to four gate-
ways on a single LON, but only one can
be the master. The master is the gateway
currently generating the network “heart-
beat” used for fault isolation, and the date
and time tag used by field devices for log-
ging calibration and alarm events.
