1.1 What is MRMS-IC?
1.2 Before You Begin
Multi-Run Multi-Station (MRMS) software with Industry Canada (IC) /
Measurement Canada approvals is a software application that allows the
ControlWave Micro controller to manage up to six (6) natural gas
measurement stations.
The MRMS-IC application consists of:
A ControlWave project file (*.PRO) pre-programmed for multi-run
multi-station natural gas measurement.
A customized flash configuration profile (*.FCP) file that configures
the ports, audit, and archive parameters of the ControlWave Micro
for the MRMS_IC.
A TechView session. This includes the TechView session file
(*.TVS), associated *.INI files, and a set of HTM menus customized
for the MRMS-IC application. You use these menus to configure the
application.
You must install the ControlWave Micro controller on site and
connect field devices to its I/O modules. For information on
ControlWave Micro hardware, see document CI-ControlWave
Micro.
You must install OpenBSI 5.7 software including TechView on your
PC workstation. You must also install the latest service pack and
patches (Service Pack 2, Patch D). See the OpenBSI Utilities
Manual (D5081), the BSI_Config User’s Manual (D5128), and the
TechView User Manual (D5131) for details on installation
requirements.
Issued: May-2012 Getting Started 1-1
ControlWave MRMS-IC Configuration Manual (D5140)
You must connect the PC workstation to the ControlWave Micro
controller. You can communicate using a serial cable or an Ethernet
cable. Cable diagrams are included in CI-ControlWave Micro.
The ControlWave Micro must be running a flash configuration
profile file (*.FCP) compatible with MRMS-IC software. For
information on updating FCP files, see Chapter 5 of the OpenBSI
Utilities Manual (D5081).
The ControlWave Micro must be running the ControlWave project
(*.PRO) file configured for the MRMS-IC. See Chapter 7 of the
OpenBSI Utilities Manual (D5081) for information on downloading
a ControlWave project (*.PRO) file.
Note: If you ordered your ControlWave Micro with MRMS-IC
software pre-installed, the FCP and PRO files are already loaded
when the unit ships from the factory.
1.3 Installing MRMS-IC Software
Note: MRMS_IC runs on the following Windows operating systems:

For an IP connection, click: Start > Programs > MRMS_IC >
MRMS_IC_IP_tvs
For a serial connection, click: Start > Programs > MRMS_IC >
MRMS_IC_Serial_tvs
From a desktop icon, similar to those below, or from the
\MRMS_IC\SUPPORT folder, double-click the IP or serial TVS file,
depending upon your type of connection.
Figure 1-8. MRMS_IC TVS file icons
For IP communication, see Section 1.4.1 MRMS_IC IP Startup.
For serial communication see Section1.4.2 MRMS_IC Serial Startup.
Note: Although you can view data through an IP connection, the
MRMS-IC application only allows configuration changes when
you establish a physical serial connection to serial
communication port 1 on the ControlWave Micro.
Once you start the TVS file for IP operation, TechView opens the
Runtime Configuration Parameters dialog box:

Chapter 2 – Configuring Inputs and Outputs (I/O Tab)
This chapter discusses configuring the MRMS-IC application to accept
field inputs and outputs (I/O). This is accomplished from the MRMSIC’s I/O tab.
Note: Although you can view data through an IP connection, the
MRMS-IC application only allows configuration changes when
you establish a physical serial connection to serial
communication port 1 on the ControlWave Micro.

2.1 I/O Tab
Click the I/O tab to display the various I/O options you can configure.
We’ll discuss each of these in the sections that follow.
To configure an
I/O function or
feature, click on
its button.

2.2 I/O Usage
When you click the button on
the I/O tab, the I/O Usage page displays a graphical representation of
the ControlWave Micro, showing each of the I/O modules detected by
the MRMS-IC. If MRMS-IC cannot detect a particular module or an I/O
slot is empty, its graphic shows “Not Present.” MRMS-IC only uses
Mixed I/O modules.
Click on the graphical
representation of a module
to configure its I/O.
I/O modules
Figure 2-2. I/O Usage Screen Showing I/O Modules Detected
When you move the cursor over the CPU module, an Expansion
Communication (ECOM) module, or any I/O module, you’ll see a
yellow box on the screen. To configure I/O, follow these steps:
1. From the I/O tab, click the I/O Usage button.
2. Position the cursor over the I/O module you want to configure; a
yellow box indicates the cursor position on any configurable
module.
3. Click on the module you want to configure. This opens a screen
showing the possible choices for I/O. The Mixed I/O Module
shows multiple types of I/O (see Figure 2-3).

ControlWave MRMS-IC Configuration Manual (D5140)
Figure 2-3. Mixed I/O Module
4. The I/O assignments in the MRMS-IC application are fixed
based on the I/O slot. Because you can have an expanded
communication module (ECOM) in either I/O slot 1 or 2, I/O
designations begin with the right-most slot and go in reverse
order. In other words, the mixed I/O module in I/O slot 6 holds
user DI1, whereas the mixed I/O module in I/O slot 1 holds user
DI6.
5. Configuration is limited based on the I/O type. Refer to the sub-
sections that follow.
Note: You may have noticed that when the cursor is left hovered over
an IO point, the graphics to the left display the applicable
connection points for direct and remote IO.

Figure 2-4. Connection Points for Physical I/O
Notes:
The MRMS-IC application only uses Mixed I/O modules.
Depending upon your particular configuration, you might not use all
the inputs or outputs in a particular meter run or station.
If you have I/O that comes from an ultrasonic flow meter or a multi-
variable transmitter that communicates with the MRMS-IC through
a communication port, instead of an I/O module, you configure it
from the UFM or Transducer pages, discussed later in this chapter.

This read-only field shows the engineering units for this
variable.
This read-only field shows the value for this variable
when the MVT receives a 4mA field input.
This read-only field shows the value that, when added
to the Zero value, represents what the process

is 20mA.
Typically, you would only use the local DLM if you are a very
advanced user and need to perform communication troubleshooting
for a particular port.
The local DLM only displays the first 80 characters of a message.
The local DLM only captures messages approximately every half
second, therefore, it can miss some messages.
Click the button on the I/O tab to
activate the Data Line Monitor function. The DLM includes the
following fields:
