CPUM MK2 600-050-000-001(620-021-110-113）

Product Introduction

The VM600Mk2 CPUMMk2 + lOCNMk2 rack controller and communications interface module is designed for operation with the second generation of VM600Mk2 rack-based machinery protection system, from Parker Meggitt's vibro-metere product line.The CPUMMk2 + IOCNMk2 module consists of central processing unit (CPU) and input/output (interface) modules that together act as a system controller and data communications gateway for VM600Mk2 systems.

In critical applications where the cost of failure is high, module redundancy with two CPUMMk2 + IOCNMk2 modules per VM600Mk2 systemrack (ABE04x) can be used to obtain true rack-level communications redundancy. This is a cost-effective solution where increased communications reliability and availability are required, for example, to help ensure uninterrupted operation in criticalenvironments.

Alteratively, module redundancy can be used to implement complex communication configurations that require more than the two fieldbuses available per CPUMMk2 + IOCNMk2 module.

Case Study

CPUMMk2 600-050-000-001(620-021-110-113）

Upgrading and optimizing the VibroSight condition monitoring system for an offshore oil platform.

The VibroSight system consisted of two databases on two separate computers, running software version 2.12.4 since 2015. The system contained 26 XMV16 cards installed in 16 VM600 racks, providing a total of 300 vibration dynamic input channels. The system monitored the operational status of 32 devices, including turbine generators, pumps, and compressors. The goals of this upgrade were: firstly, to upgrade the VibroSight software, improving its data logging and retrieval performance; and secondly, to upgrade the underlying IT infrastructure, improving network security while reducing complexity.

How did we do it?

The client decided to leverage the performance improvements of VibroSight version 4.1.3 to replace two older overseas servers with a modern server running Windows Server 2016. The original two VibroSight server instances were merged into one and run on this new server.

To enhance network security, the solution was to add a mirrored VibroSight server and database locally, identical to the local server's database. For the new local server, a virtual server hosted on Microsoft Azure was chosen as the optimal solution. This allows status monitoring analysts to access the local database without needing to access a more network-sensitive overseas platform.

Prior to field deployment, the VibroSight configuration and Mimic project were migrated, tested, and optimized to the latest version in the background.

The field operation proceeded as follows:

Stop the existing VibroSight server.

Back up existing data.

Upgrade the VM600 firmware.

Install the latest version of VibroSight on the new server computers at sea and on land.

Verify and adjust computer and firewall settings to ensure communication between different system components.

Configure and set up the new VibroSight server.

Verify that data logging and data visualization functions are working correctly.
