This chapter describes the 4-channel Quantum Meter Proving Module (called “MPM ” in this document). It also
explains how the Schneider Automation Series Quantum PLC reads input data from a Quantum module.
Shipped with your module is an MS-DOS formatted floppy disk titled “Quantum Runtime Files,” Spectrum
Controls, Inc. The disk contains runtime files that are required to use all versions of this module. Files include
an ID file, parameter screen software, help file, and multiplexing software examples for 4X and 3X register use.
NOTE NOTE NOTE NOTE NOTE The module is used with a field wiring terminal block, Modicon 140 XTS 002 00 or 140
CFA040 00 40-pin cablefast. Either of these must be ordered separately.

General Description General Description General Description General Description General Description
The Quantum MPM module is designed for flow meter applications that require specialty features such as pulse
fidelity checking and pulse interpolation for short run prover testing. It supports both AC and DC input signals
from flow meters. The module conditions the inputs to standard digital levels. It stores the converted data in its
image table for retrieval by any Quantum PLC.
The module communicates with the PLC and receives its power through the PLC backplane from the +5VDC
rack power supplies. No external power supply is required.
Your MPM supports connections from any combination of flow meter devices, with different input voltage
ranges. Each channel is individually configurable via software for a specific input device and provides rate and
limit detection. Flow mode and input range are configured in two channel groups.
