A-B 1746-MPM Mold Pressure Module

What the module does

The module processes and extracts cyclic injection molding data for 

display on your PC, and responds to alarms that you set to monitor 

critical molding parameters. 

When used with the Pro-Set 200 Injection Molding Control System, 

the module helps you:

• achieve a quicker setup time to obtain optimum part quality

• maintain that quality over the production run

The module and associated DARTWin software help you to set up the 

injection molding machine for optimum performance. Then you set 

alarm limits on critical parameters to detect deviations while making 

parts. You can also set a critical mold pressure to transfer the injection 

process each machine cycle. 

The module is designed for use with the SLC 5/03 (or later) processor. 

You program it to interface with the injection molding machine. The 

module has two independent channels to accept analog pressure inputs 

from sensors or from the SLC processor across the backplane. It 

returns alarm signals and processed molding parameters to the SLC 

processor for your application programming and to your PC for 

graphic display. We show the module in a typical Pro-Set 200 system.

Wiring Notes

• Ground cable shields at one end only.

• Isolate signal wiring from power lines and sources of electrical noise.

• Do not exceed 10V dc on any input terminal.

• Outputs +Exc, +T/R, and -T/R must have a minimum load of 1K ohms.

referenced to analog common.

Module I/O

Inputs

The module has two independent channels that you configure to process 

signals from machine sensors (default) or from the SLC output image table 

across the backplane.

Outputs (Summary Data)

The module processes a frame of summary data for each molding cycle, 

and alternately makes available the previous frame for display. It does this 

for channels 1 and 2. Your ladder logic can read summary data from the 

module’s M0/M1 files. You can observe summary data displayed on a PC 

equipped with DARTWin software. The PC must be linked to the module 

with DARTNet network from RJG Technologies, Inc.

Configure the SLC Processor (including I/O, M0/M1, and G file)

This procedure is based on RSLogix500 programming software, version 

2.0 or later. For other software, the procedure may vary.

Configure the SLC processor, I/O, size of M0/M1 files, and G file offline 

to match your system layout. 

1. With the File pull-down window, open the ladder file associated with 

this project, or create a project (ladder file) for it.

2. If you have not already done so, select the Controller Properties icon 

and launch it. Then select/enter the type of SLC processor.

3. Select the I/O Configuration icon and launch it. Then select/enter:

A. Slot number in the I/O chassis for this module

If using this module in a Pro-Set 200 Injection Control System, 

assign this module to slot 7.

B. Module ID (12935), entered under “Other” in the I/O Module window.

Important: When you enter the module ID, the processor automatically 

reserves the required number of I/O image table words. The location of 

those words in the I/O image table is determined by the module’s slot 

location in the I/O chassis. Slot location is a required addressing unit. 

For example, I:e.6 locates the 6th word in the block of input image table 

words assigned to the module in slot e that you entered in A, above. 

C. If you have not already done so, enter the size of I/O chassis and the type of power supply.

4. Select the Adv Configuration icon and launch it.

Then select/enter:

A. Length of M0/M1 files at 106 words, each (listed in section 11).

B. Length of G file at 94 words.
