Vibro-Meter VM600 CPUM Order Number: 200-595-041-113
I. Product Description
Brand: Swiss Vibro-Meter
Card Name: VM600 CPUM Rack Main Controller / Communication Controller Card (Single Unit Non-Redundant Version)
Required Accessories: Must be paired with a rear IOCN interface card for use. The CPUM is installed in the front slot, and the IOCN is placed in the corresponding slot on the rear side of the chassis. They communicate through the backplane VME bus, and neither can be missing.
System Application: The brain of the entire VM600 cabinet (MPS Mechanical Protection System / CMS Equipment Status Monitoring System), uniformly controlling all MPC4 vibration cards, AMC8 temperature cards, and XMC16 acquisition cards within the cabinet. It is also responsible for external data communication, alarm management, and parameter configuration.
Life Cycle: The original factory has discontinued production (EOL). The original factory’s new order cycle is extremely long. The market mainly consists of disassembled test pieces and refurbished spare parts for maintenance. These are core high-priced spare parts for power plant steam turbines and refining centrifugal compressors maintenance.
Configuration Software: VM600 MPSx (MPS1/MPS2), used for parameter download, fault reading, firmware upgrade; The upper-level monitoring software is VibroSight.
Model Code Disassembly (200-595-041-113)
200-595: Prefix of the main material category for the CPUM controller card
041: Hardware communication configuration version, supporting Modbus TCP (dual network ports) + Modbus RTU (serial port). The panel comes with an LCD local display and operation keys
113: Hardware revision / firmware batch code. The firmware and port definitions of other tail numbers (031-111, 045-114) in the same category are incompatible and cannot be directly replaced on the machine
Distinguish Redundant Version: CPUM is a single rack single controller; CPUR + IOCR supports dual controller hot redundancy. The order prefix is 600-007. The hardware of the two cannot be interchanged.
Hardware Configuration and Interfaces
1. On-board Core Configuration
Memory: 512MB RAM + 512MB Flash, storing configuration parameters, SOE event records, alarm logs, and waveform cache
Structure: 6U VME European card type, supports hot swapping, and can be replaced with spare parts without downtime
Power Supply: Powered by the 24VDC backplane of VM600 cabinet, compatible with redundant power supply RPS6U. Typical power consumption is approximately 8W
Front Panel: Small LCD display + SLOT/OUT/ALARM RESET keys. Can locally view real-time values of each channel vibration / displacement / temperature, alarm status, and reset all cabinet alarms with one button
2. External Communication Interfaces (Commonly derived from CPUM + IOCN)
Dual RJ45 Ethernet Ports: Main / Backup Modbus TCP channels, uploading / downloading unit data to DCS/SCADA/VibroSight; Supports dual network communication redundancy
RS232 Debug Serial Port: Laptop directly connects through MPSx software, uploading / downloading protection thresholds, reading fault codes, and flashing firmware
Multiple RS422/RS485 Serial Interfaces: Modbus RTU bus networking, connecting to third-party control systems
Backplane VME High-speed Bus: Real-time data interaction and alarm determination logic with all measurement cards in the chassis
Core Functions Rack centralized control: Uniformly manage all MPC4/AMC8/XMC16 daughter cards, perform vibration / shaft displacement / temperature alarm (alert / danger) determination, and output trip logic.
Data gateway forwarding: Transmit monitoring data such as shaft vibration, bearing vibration, axial displacement, speed, and bearing temperature through Modbus RTU/TCP to the DCS, enabling remote monitoring in the control room.
Event traceability SOE: Record the timestamp of alarm triggering, channel over-limit, and card failure at the millisecond level. After the unit trips, it can precisely trace the cause of the fault.
Online configuration maintenance: The MPSx software remotely configures channel range, filtering, alarm delay, and interlock logic. It supports automatic identification of daughter card hot plugging.
Whole machine self-diagnosis: Continuously self-check CPU operation, backplane bus, network interface communication, and IOCN interlock status. Abnormalities in itself immediately trigger the rack’s common fault alarm.
