When you build or expand a VM600 machinery protection system, the CPUM 200-595-067-114 and MPC4 combination must be selected as one matched set. The CPUM manages rack communication and system supervision, while MPC4 cards handle protection measurement, trip logic, and channel processing. If this pair is not compatible, the result is usually bus communication failure, incorrect trip behavior, or a rack that cannot be commissioned.
1. How CPUM 200-595-067-114 fits into VM600 system selection
The CPUM 200-595-067-114 is the communication processor and rack supervisor for a VM600 system. It does not directly measure shaft vibration or casing acceleration. It collects processed protection data from MPC4 cards over the rack backplane and makes that data available to the plant DCS, PLC, or condition monitoring system.
When selecting this CPUM, confirm:
- Required communication interface and protocol (Ethernet, serial, Modbus, plant fieldbus).
- Number of MPC4 and I/O cards to be supervised in the rack.
- Redundancy requirement. Single CPUM is standard for many auxiliary machines; critical trains may use redundant communication paths.
- Backplane and rack compatibility. CPUM 200-595-067-114 is designed for the 19-inch rack with backplane 204-040-100-012.
- Firmware compatibility with existing MPC4 cards.
Do not select the CPUM part number alone. Select it together with the MPC4 channel plan, because communication loading and data register mapping change with the number of protection cards.
2. MPC4 pairing rules: match channel plan to protection function
MPC4 is the machinery protection card family in the VM600 rack. The common base part number is MPC4 200-510-017-017, but other versions such as 200-510-071-113, 200-510-078-115, 200-510-150-031, and 200-510-041-022 differ in relay outputs, trip logic, and approved application range.
Pairing rules:
- Count protection channels before selecting MPC4 quantity. Each MPC4 supports four channels. A pump with two radial vibration probes and one axial thrust probe uses three channels on one MPC4.
- Match sensor type. Eddy current proximity probes such as TQ402 111-402-000-013 require an IQS450 signal conditioner before the MPC4 input. Piezoelectric accelerometers such as CA202 144-202-000-203 may use IPC704 signal conditioning. Dynamic pressure sensing via CP515 143-515-000-111 is used for combustion or pressure pulsation monitoring.
- Verify trip output logic. Some MPC4 versions provide internal relay outputs, while others rely on an external RLC16 200-570-101-013 relay card. Uncertain relay contact ratings should be confirmed before ordering.
- Check firmware pairing with CPUM 200-595-067-114. An older MPC4 may work, but firmware revision mismatch can cause register mapping errors or no data display.
3. Rack, slot, and backplane requirements
The VM600 rack is normally based on the 204-040-100-011 mechanical rack and 204-040-100-012 backplane. The CPUM 200-595-067-114 must be placed in its dedicated processor slot, not in any free I/O slot. MPC4 cards, IOC4T modules, and IQS450 conditioners are inserted in the remaining I/O positions.
Before installing:
- Inspect rack guide rails. Worn guides cause poor module seating and intermittent backplane contact.
- Check backplane ventilation spacing and cable dressing. Tight cable bundles under the rack can stress connectors.
- Use proper grounding. Connect the rack ground stud to the plant protective earth. Do not rely on the cabinet door hinge for grounding.
- Route cables separately: probe extension cables, relay trip wiring, and communication cable should be separated from power cables.
4. Recommended pairing configuration for rotating equipment
A practical starting configuration for a medium-size compressor or turbine with two bearing sections:
| Module | Part number | Quantity | Role |
|---|---|---|---|
| Communication processor | CPUM 200-595-067-114 | 1 | Rack data, alarms, DCS/PLC communication |
| Protection card | MPC4 200-510-017-017 | 2 | 8 channels for radial vibration, thrust, speed |
| I/O module | IOC4T 200-560-000-016 | 1 | Digital/analog field I/O |
| Signal conditioner | IQS450 204-450-000-001 | 2 | Proximity probe signal conversion |
| Proximity probe | TQ402 111-402-000-013 | 6 | Shaft vibration and thrust |
| Probe cable | EA402 913-402-000-013 | 6 | Sensor to conditioner connection |
| Relay card | RLC16 200-570-101-013 | 1 | Trip relay expansion |
| Rack/Backplane | 204-040-100-011 + 204-040-100-012 | 1 set | Mechanical installation |
This is a selection example, not a universal bill of material. The final quantity changes with machine type, monitoring point count, and required trip outputs.
5. CPUM 200-595-067-114 vs CPUM 200-595-063-314
If you are replacing an older CPUM 200-595-063-314 with the 200-595-067-114, do not assume drop-in compatibility without checking:
- Backplane bus revision.
- MPC4 firmware and address switch settings.
- Communication protocol configuration.
- Existing IOC4T and rack address mapping.
In many cases the upgrade is straightforward, but an unverified swap can cause all rack modules to appear offline. Ask your supplier to confirm firmware compatibility before shipping.
6. Common pairing mistakes
- Ordering MPC4 without checking relay output type. A protection card without dry contact trip outputs may require an additional RLC16 relay card.
- Ignoring rack slot position. CPUM and MPC4 modules are not freely interchangeable in the backplane.
- Mixing probe and conditioner models. TQ402 probes must be matched to the correct EA402 cable length and IQS450 input configuration.
- Selecting communication hardware before confirming DCS protocol. The CPUM must be configured for the correct register map and protocol.
- Underestimating spare parts coverage. A single CPUM failure can take down the entire rack communication. Keep at least one spare CPUM and one spare MPC4 if the machine is critical.

FAQ
Can CPUM 200-595-067-114 work with older MPC4 200-510-017-017 cards?
Yes, in most cases. But check MPC4 firmware and the rack backplane revision. Older firmware may need a specific CPUM configuration.
How many MPC4 cards can one CPUM 200-595-067-114 supervise?
It depends on the rack size and backplane slot count. One CPUM can normally manage multiple MPC4 cards in a single 19-inch rack. Confirm the maximum I/O card count for your backplane version.
What if I need more trip relay contacts?
Use the RLC16 200-570-101-013 relay card, or select an MPC4 version that includes the required relay outputs. Do not exceed the rated contact current.
Can CPUM 200-595-063-314 be replaced by CPUM 200-595-067-114?
It is a common upgrade, but hardware and firmware changes must be verified. Check backplane bus compatibility and existing MPC4/IOC4T firmware.
What sensors connect to MPC4?
Typical inputs are TQ402/TQ412 eddy current proximity probes for shaft vibration and thrust, CA202 accelerometers for casing vibration, and CP515 dynamic pressure sensors for pulsation monitoring.
