4-2 Operation

Revised

Mar-2011

Power

Down

To remove power from the ControlWave ExpressPAC, unplug
connectors TB1 and TB2 from the CPU/System Controller board.

4.2 Communicating with the ControlWave ExpressPAC

You communicate to the ControlWave ExpressPAC by connecting a
cable between a port on your PC workstation and one of the
ControlWave ExpressPAC ports.

The port at the PC workstation must match the configuration of the
ControlWave ExpressPAC port.

4.2.1 Default Comm Port Settings

As delivered from the factory, ControlWave ExpressPAC
communication ports have default settings. Table 4-1 details these
defaults.

Table 4-1. Default Comm Port Settings (by PCB)

Port

PCB

Default Configuration

COM1

CPU

RS-232; 115.2 Kbps using BSAP or ControlWave Designer
protocol.

COM2

CPU

RS-232; 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
ControlWave Designer protocol

COM3

CPU

RS-485; 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
ControlWave Designer protocol. Intended for use with Bristol
3808 transmitters. You use jumpers W12 through W16 to
configure COM3 for either RS-232 or RS-485

Note

: You can re-enable the factory comm settings at any time by

setting switch 3 on the CPU module’s SW3 to “OFF.”

Ethernet

Using an optional Ethernet port (located on the CPU module), you can
connect either directly or through a network to a PC equipped with an
Ethernet port. The default IP address and mask for the Ethernet port is:

 ETH1 IP Address: 10.0.1.1 IP Mask: 255.255.255.

4.2.2 Collecting Data from the ControlWave ExpressPAC

OpenBSI utilities such as DataView, Data Array Save/Restore and
Harvester allow you to collect real time data (values of variables, array
values, alarm messages) and historical data (audit records, archive files)
from the ControlWave. See the OpenBSI Utilities Manual (D5081) for
details. SCADA software such as OpenEnterprise can then present this
data to an operator in the form of graphical displays and reports.
