Introduction

This is the users’ manual for the Moore Industries

TMZ PC-Programmable MODBUS Temperature

Transmitter (TPRG: RTD, T/C, Ohms, mV and

Potentiometer inputs). It contains all of the

information needed to conﬁgure, install, operate and

maintain this instrument.

About this Manual

Wherever you see a “Note”, “Caution” or “WARNING ”

pay particular attention.

WARNING - Hazardous procedure or condition that

could injure the operator.

Caution - Hazardous procedure or condition that could

damage or destroy the unit.

Note - Information that is helpful for a procedure,

condition or operation of the unit.

Figure 1. The TMZ (TPRG)

The TMZ

The TMZ is a PC-Programmable, user-conﬁgurable,

signal converter. It has a digital output and retains the

high accuracy of an Analog to Digital converter without

the limitation of low resolution which is associated with

analog outputs. The multi-drop nature of the RS-485

port allows the connection of up to 32 units on a single

drop of cable that consists of two pairs of wires. The

TMZ has a READY LED to indicate the health of the

unit and an INPUT LED to indicate status.

Model and Serial Numbers

Moore Industries uses the model and serial numbers

of our instruments to track all information on each

unit that we sell and service. If a problem occurs

with your TMZ, check for a tag afﬁxed to the unit

listing these numbers. Supply the Customer Support

representative with this information when calling.

Inputs

Refer to Table 4 for input ranges and accuracies of the

TMZ (TPRG).

Outputs

The TMZ has a standard RS-485 port that supports

the MODBUS RTU protocol.

Figure 4. Hooking-Up the TMZ (TPRG)

Conﬁguring the TMZ

One of the beneﬁts of the TMZ is that there are no

internal or external controls to adjust or settings to

change. All operating parameters are set using a

PC and Moore Industries’ Intelligent PC Conﬁguration

Software.

The software settings are downloaded to the

transmitter in the form of a Conﬁguration File and

stored in the instrument’s memory. You can save a

backup copy of the ﬁle on your PC hard drive or disk.

The transmitter communicates with the PC through an

RS-232 connection to the PC’s serial port or through

the MODBUS output with a ﬁxed baud rate at 19.2k.

No Transmitter Needed

It is not necessary to connect the transmitter to a PC

to create conﬁguration ﬁles using the software. The

Conﬁguration Program can be run without connecting

a transmitter, and most parameters can be set

without the beneﬁt of input from a sensor or TMZ.

This makes it easy to create a set of operating

parameters, save them to disk, and download them to

one or more transmitters at a later time.

The TMZ must be connected to the PC in order to:

perform sensor trimming; assign a tag, descriptor or

message; receive (via download) a conﬁguration ﬁle;

and save the conﬁguration ﬁle from the transmitter’s

memory.

Connecting the TMZ to the PC

Connect the RS-232 end of the cable to the PC’s COM

port.

See Table 6 for information on the necessary

equipment.

Installing the Conﬁguration

Software

Refer to Table 6 for the equipment needed.

1. Insert the Moore Industries Interface Solution

PC Conﬁguration Software CD into the CD

drive of the PC. Access the CD and open the

“TMZ PC Conﬁguration Software” folder.

2. Double-click the installation program located

in the folder. Follow the prompts to correctly

install the program.

Once the Conﬁguration Program is installed on the

PC, the TMZ can be connected to equipment to

simulate input and monitor output. You can then

change the transmitter’s operating parameters.

The latest version of our Conﬁguration Software for

your TMZ unit is also available for download on our

website www.miinet.com.

Figure 5. TMZ (TPRG) PC Conﬁguration Software Screen

PC Conﬁguration Software Summary

Once the default conﬁguration has been saved to disk,

it is safe to program other parameters. The PC

Software is made up of these sections:

1. Tool Bar/Status Bar– Dropdown menus and

corresponding icons allow you to perform various

functions throughout the PC Conﬁguration Program.

Refer to the Status and Tool Bar Legend section for a

complete description.

2. Program Status– This portion of the program

displays the activity (idle, monitoring, downloading,

uploading) of the connected unit.

3. Device ID– Displays your unit conﬁguration

(HLPRG/TPRG), ID, Hardware revision and Software

revision.

4. Identiﬁcation Parameters– Use this parameter to

place an identifying “Tag” (8 alphanumeric characters

max.), “Descriptor” (16 alphanumeric characters max.)

or “Message” (32 alphanumeric characters max.). You

may also use the Quick Set feature to set your Ta g

and download it.

5. Device Conﬁguration– Displays the Input and

MODBUS parameters you have chosen as settings for

your TMZ.

6. Input Type– Select your input type (RTD, T/C,

Ohms, mV and Potentiometer) and characteristics.

7. Variables– Displays the value of the Process

Variable that is being monitored, the Reference

Junction temperature, the scaled output and the

Custom Curve output.

8. Device Status– Notiﬁes of any errors or conditions

which are outside of tolerance range.
