A failure of this application — for whatever reason -- may leave an operating process without appropriate
protection and could result in possible damage to property or injury to persons. To protect against this, you
should review the need for additional backup equipment or provide alternate means of protection (such as
alarm devices, output limiting, fail-safe valves, relief valves, emergency shutoffs, emergency switches, etc.)

1.1 What is the Station Manager?
Station Manager is an application that allows the ControlWave Micro
controller to manage up to six (6) natural gas measurement stations that
include, among all the stations, up to:
Maximum of six (6) or eight (8) meter runs, depending on the
software version.
Eighteen (18) control valves.
Eight (8) PID loops per station for control. You can configure each
station for tube switching, and Station Manager supports indication
of bi-directional measurement for up to three (3) pairs of stations.
Three general purpose proportional integral derivative (PID) loops.
The Station Manager application consists of:
A ControlWave project file (*.PRO) pre-programmed for mult-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 Station Manager.
A TechView session. This includes the TechView session file
(*.TVS), associated *.INI files, and a set of HTM menus customized
for the Station Manager application. You use these menus to
configure the application.
Issued: May-2019 Getting Started 1-1
ControlWave Station Manager Configuration Manual
Note: Two versions of Station Manager are available for purchase:
Station Manager 6-Run supports up to six meter runs and also
supports communication to HART® devices, and a Coriolis Modbus
interface. Station Manager 6-Run has Measurement Canada
approvals; see Appendix C for details.
Station Manager 8-Run supports up to eight meter runs, without
HART® support, and without the Coriolis Modbus interface.
The maximum number of meter runs also affects the number of
certain components you can define, for example the number of
ultrasonic flow meters (UFMs) or gas chromatographs (GC).
1.2 Before You Begin
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.
For this version of Station Manager, your ControlWave Micro must
have 64MB of SDRAM and 5.60 firmware (or newer).
For full functionality, your ControlWave Micro should not use the
System Controller Module (SCM) used with the ControlWave EFM;
you should use a power supply sequence module (PSSM).
You must install OpenBSI software (5.9 or newer) including
TechView on your PC workstation. See the OpenBSI Utilities
Manual (D5081), the BSI_Config User’s Manual (D5128), and the
TechView User Manual (D5131) for details on installation
requirements.
For optimum results, you should set the screen resolution on your
PC to 1280 x 1024, your screen refresh rate to 60 Hz, and DPI to 96
(normal size).
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 Station Manager 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 Station Manager. See Chapter 7 of
the OpenBSI Utilities Manual (D5081) for information on
downloading a ControlWave project (*.PRO) file.
Your Station Manager application must be properly licensed; if you
purchased a license dongle, you must run the Application Licensing
tool and install the dongle in your USB port. You must then reset

5. Continue assigning Station Manager functions to their applicable
field I/O points. See the sub-sections below for information on
the different I/O module types.
Notes:
Only assign a given function to one input I/O point. If you
subsequently assign the same function to a different input point,
Station Manager re-assigns it to your newer choice and disconnects
it from the earlier choice.
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 Station Manager
through a communication port, instead of an I/O module, you
configure it from the UFM or Transducer pages, discussed later in
this chapter.
To return to the I/O Usage page from any page underneath it, click
