Default Configurations for Quick Start
If you are using the default input type, you can simply connect your input and output devices to the control,
then power up the control and press the slider or the +/- keys on the front of the control to change the set
point from the default value (75°F) to the desired value. As the Set Point increases above the Process Value,
output 1 will come on and begin driving the output device.

Using Watlow Software to Configure Parameters
You can set up all parameters directly from the PM PLUS™ front panel via the
Setup
List, as explained
in this manual, or use Watlow CONFIGURATOR or COMPOSER on a PC. If you choose to use Watlow
CONFIGURATOR or COMPOSER software to set up the PM PLUS™ from your PC, you'll need to wire
communications (see Chapter 2). There are two ports (instances) for communications. Port 1 is dedicated
to Standard Bus communications. Port 1 may also be used for Modbus
®
RTU if purchased. Port 2 may be
used with Modbus
®
, DeviceNet, Ethernet/IP, J1939 CAN, or Profibus.
You will need the parameter IDs listed in the table: "Setup Lists" if you use Modbus
®
or another commu-
nication protocol to write to the PM PLUS™ from a configuration software. For detailed information about
Modbus
®
, CIP or Profibus addresses, and Data Types, refer to the "EZ-ZONE All Register List." on the
Watlow website.
Range selections can be made by writing the enumerated value of choice using any of the available commu-
nications protocols. For example, to turn an analog input sensor off (as seen at
Operations — Setup — Ana-
log Input — Sensor Type
) using Modbus
®
, write the value 62 (off) to register 368 and send that value to the
control. For complete instructions, refer to that software's user manual available on Watlow.com.
