Product Description

Meggitt Vibro-Meter CPUM 200-595-072-422 / CPUM 200-595-072-122 is a VM600 modular CPU card variant group. It provides the processing layer that receives data from the VM600 rack and presents the configured controller and communications services to the external system.

Within the rack, CPUM 200-595-072-422 / CPUM 200-595-072-122 exchanges data with the installed monitoring, protection and interface cards through the VM600 backplane. The card family supports two Ethernet interfaces and two serial interfaces, with front and rear connections assigned to different physical access points.

On CPUM 200-595-072-422 / CPUM 200-595-072-122, the firmware and hardware designation is part of the CPU card configuration. The installed card passes rack data to the configured Ethernet or serial path after the rack connection has delivered the module data.

Communication and Connectivity: Controller Ports

CPUM 200-595-072-422 / CPUM 200-595-072-122 separates its internal rack data path from the Ethernet and serial access points.

Ethernet path

The CPUM and associated IOCN provide the two Ethernet access points used by the configured VM600 communications path.

Serial path

The front service connection is RS-232, while the rear isolated interface can use RS-232 or RS-485.

Backplane path

The VM600 backplane carries the internal card data before it reaches an external port.

Monitoring and Control: Rack Processing

CPUM 200-595-072-422 / CPUM 200-595-072-122 processes the data presented by the cards installed in the VM600 rack.

Input from cards

Measurement and protection cards deliver their data through the rack connection.

Controller layer

The CPUM provides the central CPU function for the configured rack.

External handoff

The configured Ethernet or serial interface carries the processed data beyond the rack.

Common Questions

Which interface is the front service connection on CPUM 200-595-072-422 / CPUM 200-595-072-122?

CPUM 200-595-072-422 / CPUM 200-595-072-122 uses the front CPUM service path for the RS-232 interface. The rear interface belongs to the IOCN-side connection and is electrically separate from the front service port.

How does CPUM 200-595-072-422 / CPUM 200-595-072-122 receive measurement data?

CPUM 200-595-072-422 / CPUM 200-595-072-122 receives data from the installed VM600 cards through the rack backplane. The CPU card then presents the configured data through its external communication path.

Are the two Ethernet interfaces on CPUM 200-595-072-422 / CPUM 200-595-072-122 field sensor inputs?

No. The Ethernet interfaces on CPUM 200-595-072-422 / CPUM 200-595-072-122 are communication ports for the controller and network path. Sensor and protection signals enter through the associated VM600 measurement or I/O cards.

Why are 200-595-072-422 and 200-595-072-122 listed together in CPUM 200-595-072-422 / CPUM 200-595-072-122?

They are two supplied CPUM identifiers grouped in one display. Their full PNR strings remain distinct because firmware and hardware designations are part of the card record.

What should be traced if the external VM600 data link is unavailable on CPUM 200-595-072-422 / CPUM 200-595-072-122?

Trace the selected Ethernet or serial cable from the external equipment to the corresponding CPUM or IOCN connection, then verify the rack backplane path into CPUM 200-595-072-422 / CPUM 200-595-072-122.

Can CPUM 200-595-072-422 / CPUM 200-595-072-122 be documented without the paired IOCN card?

The CPUM card can be identified independently, but the complete communications path also includes the IOCN-side rear connections when those are used. The rack record should therefore show both cards and their cable roles.
