Section 4: Operation
This section covers the following topics:
▪
Powering Up/Powering Down the Device
▪
Establishing Communications
▪
Communicating using the HMI Module
This section describes day-to-day operation of the Emerson FB1200 Flow Computer including how
to turn it on and off and how to communicate with it.
4.1 Powering Up/Powering Down the Device
1.
Remove the front end cap.
2.
Terminal block TB1 includes connections for DC power (+DCIN, -DCIN) and solar power
(+SPIN, -SPIN). Battery power (which is also used with solar power) has its own internal
connections.
▪
Plug in TB1 to activate DC or solar power. If your device uses an internal battery and it
is not connected, connect it as discussed in 2.12.3 Connecting Battery Power.
▪
Unplug TB1 to deactivate DC or solar power. If your device uses an internal battery,
disconnect the main battery.
This turns on (or shuts OFF) power from either an external power supply or the battery
pack/solar panel.
Note
When you turn power on, the backlight on the HMI module lights, momentarily turns off and then
remains lit while the INPUT LED blinks. After approximately one minute the initialization process
finishes and the HMI starts to display live data.
4.2 Establishing Communications
The flow computer supports three ways to establish communications: through the host SCADA
system, through a local laptop computer running FBxConnect, or through the HMI module.
4.2.1 Communicating with the SCADA Host
Communication to the flow computer through a SCADA host computer requires configuration of
the host computer software, which varies depending upon whether you are using OpenEnterprise
or another host software package. Much of this configuration is beyond the scope of this topic, but
no matter which host you are using, there are certain steps you must take:
