Vertex M 24-Point Continuous Monitor
TM
A.1 Overview
The application provides an analog output option for the
Vertex M by utilizing a second SLC 5/03 PLC rack. This
rack communicates with the primary PLC via the DF1
Fieldbus option.
A.2 Hardware Requirements
Primary PLC The primary Vertex M PLC must be
configured with the DF1 Fieldbus option. This
option includes the following hardware:
Prosoft MVI46-DFCM module installed in
(1)
slot 2
(1) Prosoft RJ45 to DB9 adaptor cable
Secondary The secondary PLC requires the following
PLC
items
(1) 1746-A7 Rack
(1) 1746-P4 Power supply
(1) 1747-L532 SLC 5/03 Processor
(1) RS232 Null Modem Cable
Spectrum Controls 1746sc-INO4i Analog
(6)
Output Modules
Any required mounting hardware to mount
PLC rack in Vertex M Chassis
A.3 Configuration Requirements
Primary PLC – In addition to loading the correct
program for the DF1 Slave, the primary PLC must also
have the channel number and baud rate for the PLC
setup properly. The procedure for configuring these
parameters is documented in
Utility. The 'Fieldbus' radio button must be selected for
DF1, the 'Set Address' field needs to be set to 10 and
the 'Set Baud Rate' field set to 19,200.
The Prosoft DF1 module in the primary PLC also
has one required jumper setting. The com2 jumper
must be in the RS232 position. This is the default
configuration.

Section 3.6 Configuration
Secondary PLC – The secondary PLC must be
assembled with the 5/03 module in the first slot (slot 0)
and all other slots populated with Spectrum Controls
1746sc-INO4i modules. No configuration is needed
on these modules, however there is a user settable
dip switch for selecting between rack loop power and
external loop power. This is an application specific
setting, the default is rack power.
The RS232 port on the secondary PLC's 5/03 module
(bottom port on module) must be connected to the
Prosoft module's port 2 (middle port on module in slot
2 of primary PLC rack).
The only software configuration needed is to load the
PLC program ("VertexM AnalogOut Rack2.rss") into the
Secondary PLC 5/03 processor. The software required
to load this is RSLogix 500 and RSLinx.
Once the PLC program has been loaded, the standard
RS232 port will be configured for communication
with the Prosoft DF1 module and will not support the
standard COM port connection for programming. Any
subsequent attempts to load the PLC (either to restore
factory default or load program revisions) will require
following a procedure to clear the PLC memory or
communication through the DH485 port. Connecting
to this port requires a special adaptor (1747-UIC)
and cable (1747-C13). COntact Honeywell Analytics
