BCVision
Chapter 4 - BCMaster

The IES Supervisory System includes the BCMaster terminate-and-stay-resident (TSR) software. This TSR must be loaded before BCVision on the BC Supervisor. BCMaster is responsible for managing the Cubix Data Highway.

Installation

The BCMaster TSR resides in the file BCMASTER.EXE on the IES Supervisory System Diskette. It is recommended that BCVision be executed automatically each time the BC Supervisor is booted. This requires adding the following lines to the AUTOEXEC.BAT file:

bcmaster

bcvision

Note! If SNMP support is desired, VLM.EXE should be executed before BCVISION.EXE is loaded.

These commands may alternatively be entered at the DOS command line.

Unloading

To unload BCMaster, add -Unload or -u to the command as follows:

bcmaster -unload or

bcmaster -u

The screen will display a message confirming that BCMaster has been unloaded.

Help

To obtain help on BCMaster, append -help, -h, or -? as follows:

bcmaster -help

bcmaster -h

bcmaster -?

The supported command line options will be displayed.

Operation

BCMaster will use COM port 2 for data highway communications. This requires installing a Cubix Data Highway Adapter to the COM2 header on the BC Series processor. Instructions for installing this adapter are included in the IES Module Hardware Installation Guide. IBM compatible PCS assign an I/O port and an interrupt to each COM port. The assignments for COM2 will be displayed by BCMaster when it is loaded. The default I/O port is 2F8 hexadecimal, and the default interrupt is IRQ 3. BCMaster displays this configuration information when it is loaded.

When BCMaster is invoked it scans the Cubix Data Highway for Intelligent Environmental Sensors (IES). BCMaster displays the message:

Scanning for IES modules

To be found during the scan, an IES must be attached to the highway and must be supplied with power. BCMaster displays a message identifying each IES it locates. This information may be written into a file using standard DOS redirection techniques. When the scan is completed, BCMaster displays:

Scan completed.

If all of the sensors are not located by BCMaster as expected, there may be a problem with the system hardware configuration. It is suggested that the problem be remedied before running BCVision. Refer to Chapter 5 - Troubleshooting.

During the scan BCMaster retains control of the BC processor. The processor will not respond to user input until after this scan completes.
