the Input Status screen. The point will now
display a "D" (for digital) in the Type col-
umn, and will also display the current value
of the point in the Value field (ON or OFF).
9. Repeat steps 1 through 5 until all points are
defined.
When finished, the points are ready for use in E2 appli-
cations. If you wish to set up the Condensed Mode points
so that alarms from PerformanceAlert™ are written to the
E2 Advisory Log, refer to Section 8.1.1., Generic Alarm-
ing Setup .
You may wish to use the Gateway points as inputs for
Digital Sensor control applications, where you may set up
output control. Refer to the E2 User’s Guide (P/N 026-
1610) for Digital Sensor Control setup instructions.
6.3. I/O Setup for Expanded
Mode
In Expanded mode, for every PerformanceAlert™
module address set to "enable" (ENB) in the Gateway (see
step 4 of the Gateway Setup instructions in Section 5 ), the
Gateway board will emulate a 16AI board whose board
number is the same number as the PerformanceAlert™
module. When a PerformanceAlert™ module is set to "dis-
able" (DIS) in the Gateway, the Gateway board does not
use this board number, meaning it may be used by other
MultiFlex input boards.
Each virtual 16AI board address shares sixteen data
points corresponding to alarm states and sensor values
from the PerformanceAlert™ module. The point numbers
and functions are fixed and are the same for each module.
Table 6-1 lists the point numbers and their data types and
functions.
Points 1 through 11 are alarm states. They will be ON
whenever the corresponding alarm type is active on the
PerformanceAlert™ module, and OFF when the alarm type
is not active.
Point 12 represents the digital state of the Perfor-
manceAlert™’s compressor relay (ON when the compres-
sor relay is ON, and OFF when the compressor is OFF).
Points 13 and 14 are the measured currents through T1
and T3 respectively.
Point 15 is the measured temperature read from the dis-
charge line temperature sensor.
Point 16 has the same function as the alarm state point
in Condensed Mode. It is ON whenever any alarm is active
on the PerformanceAlert™ module. Consequently, when-
ever any of the points from 1 through 11 are ON, point 16
will be ON as well.
6.3.1. Expanded Mode Point Setup
To set up the Gateway’s virtual 16AI points for use in
logging, alarming, and I/O control, press
I
(IN-
PUT DEFINITIONS) to access the Input Status screen.
If you will be using the PerformanceAlert™
Gateway in Condensed Mode, skip this section
and follow the instructions in
Section 6.2., I/O
Setup for Condensed Mode.
NOTE: Expanded Mode may not be used if
networking the Gateway to an RMCC. The
RMCC will only support Condensed Mode.
