Starting with PVI Version 3.0.2, the MTC line is no longer supported!

The MTC line provides Maintenance Controller (MTC) functions for B&R Provit 5000 Industrial PCs (IPCs) (see also the "Provit 5000 User's Manual", model number MAPRV5000-0).

The MTC is responsible for the following tasks and components:

•AT PS/2 keyboard

•Panelware keypad modules

•Acquisition of operating data (controller and display unit)

•Temperature monitoring with fan control

•Battery state evaluation (good/bad)

MTC functions for configuring keys and key LEDs on the display unit and Panelware modules as well as functions for reading key scan codes are not supported. This can all be taken care of using B&R MKEY utilities.

The following topics are covered in this section:

•MTC process objects

•MTC access types

•MTC events

•MTC communication

MTC process objects

A line object, a device object, and a variable object are all needed to access an MTC variable.

Process objects of the MTC line:

Allowed object structure for MTC process objects:

MTC access types

The following table shows an overview of all access types which are regulated via a line. All access types not listed here as well as access types to the PVI base object are executed by PVI Manager and therefore work independently of the line being used. The "Access type" column indicates which access types in the MTC line can be used with which process object types.

MTC events

The following table shows an overview of all event types which can be generated from a line. All event types which are not listed are generated by PVI Manager and therefore work independently of the line being used.
