8.9 Series 1 Rack 4-20mA Analog Output Option
8.9.1 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.

8.9.3 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 "Configuration Utility" on page 51. 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.
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).
