MESSAGE WRITE SETUP SCREEN
The following setup screen is programmed to write the Evaporator mode to the Quantum™ LX (ID#1) N55:3 data le from
the SLC500’s N55:3 data le. The target address must be changed to for the Quantum™ LX.
• This Controller: SLC500
• Data Table Address: Data le location in the
SLC500
• Size in Elements: # of data le to read
• Channel: Port location on the SLC processor
(Channel 0 is the RS232 port)
• Target Device: Quantum™ Panel
• Data Table Address: Data le location in the
Quantum™ controller.
• Local Node: Quantum™ ID# (Octal)
Allen-Bradley Data Access
Data passed to and from the Quantum™ are integer
values with one decimal eld assumed unless shown
otherwise or the command is sent to select two deci-
mal elds. For example, if the data’s value is 25.5 then
the value 255 is sent. All temperatures are in degree
C and all pressures are in PSIA unless the command
is sent to select the units of the panel. A mode such
as Slide Valve mode is sent as an integer value that
represents the mode it is in. For example, a 0 is sent
if it is in manual, or a 10 is sent if it is in automatic, or
a 20 is sent if it is in Remote Communications.
The value zero (0) is used to represent an OFF status
and a DISABLED option. The value one (1), which is
received as a 10, is used to represent an ON status
and an ENABLED option. Only data values that are
designated as setpoints are modiable. Read Only is
used to help identify what data is not modiable. The
setpoint range is checked to see if it is an allowed
setting. If it is not allowed, the setting is not changed.
Reference the Quantum™ Data Tables in this manual
for the address listing and description of data.
A command has been provided that selects whether
data to and from the Quantum™ will be returned in
the units that are the default (pressure in PSIA and
temperature in Degree C) or in the units that are se-
lected to display at the panel.
EtherNet/IP
Frick Controls supports the use of EtherNet/IP (as
described on the ab.com website, under the Ether-
Net/IP heading) with LX software 6.06 and later. Ad-
dress mapping follows the Allen-Bradley N: format,
as shown in the Data Tables under the heading of AB
Address.
