System Ethernet
ETHERNET1 and ETHERNET2 provide 10/100/1000BASE-T(X) links for VM600 software, XMX16/XIO16T data and Modbus TCP exchange.
Model Information
Meggitt Vibro-Meter IOCR2 620-022-000-112 is the VM600 rear communications interface card paired with a CPUR2 rack controller. It carries processed rack data to the configured system Ethernet and fieldbus connections, and exposes relay contacts for status or alarm information.
Installed at the rear of an ABE04x VM600 rack, IOCR2 620-022-000-112 exchanges data with the front-mounted CPUR2 through the backplane. Its two system Ethernet ports serve the VM600 software and network path, while FIELDBUS1 and FIELDBUS2 each combine an RS-485 PROFIBUS DP interface with an Ethernet Modbus TCP interface.
For IOCR2 620-022-000-112, the signal flow starts with rack measurements handled by the CPUR2, continues through the backplane to the interface card, and leaves through Modbus TCP, PROFIBUS DP or the mapped RL1/RL2 contacts. VibroSight software supplies the fieldbus and relay configuration; the card does not use an independent configuration record.

Communication and Connectivity: Ethernet and Fieldbus Paths
IOCR2 620-022-000-112 routes VM600 rack data through separate system Ethernet and fieldbus interfaces.
→
Fieldbus pairs
FIELDBUS1 and FIELDBUS2 each contain an RS-485 PROFIBUS DP path and an Ethernet Modbus TCP path.
→
External handoff
The CPUR2 sends processed rack data through the backplane before the selected IOCR2 interface carries it to a DCS, PLC or fieldbus master.
Diagnostics and Protection: Relay and Status Monitoring
IOCR2 620-022-000-112 combines isolated interface paths, front-panel activity indicators and configurable relay contacts.
Relay contacts
RL1 and RL2 are SPDT / Form C outputs rated at 240 VAC and 5 A, with a 1250 VA maximum breaking capacity without contact protection.
-
Isolation barriers
The RS-485 fieldbus path is isolated to 700 V RMS and the Ethernet fieldbus path to 1500 V RMS. -
Status evidence
Link/activity LEDs identify ETHERNET1/2 and FIELDBUS1/2 activity, while VibroSight can download diagnostic logs for investigation.
Frequently Asked Questions
What is the purpose of IOCR2 620-022-000-112 in the VM600 system?
IOCR2 620-022-000-112 is the external communications interface associated with a CPUR2 controller in the VM600 rack. It carries the configured protocol service rather than processing the sensor measurement itself.
Why must IOCR2 620-022-000-112 be checked with a CPUR2 card?
In the rack path for IOCR2 620-022-000-112, the IOCR2 rear interface and CPUR2 controller form one rack communication path. Checking the interface without the paired controller can leave the backplane side, protocol setting or rack position unidentified.
What should be checked if IOCR2 620-022-000-112 has no network response?
To trace IOCR2 620-022-000-112, check the external cable and selected protocol first, then verify the rear interface connection to the CPUR2 controller. These checks separate a network-side issue from a rack-side interface problem.
Does IOCR2 620-022-000-112 connect directly to a sensor?
No. IOCR2 620-022-000-112 handles the VM600 external communications route. The sensor path enters through the configured measurement and input cards, is processed in the rack and then becomes available to the communications interface.
Is IOCR2 620-022-000-112 a complete model string?
When documenting IOCR2 620-022-000-112, it is the complete IOCR2 identifier supplied for this page and should be retained with every digit. The card family name alone is not enough to preserve the exact interface record.
How can a technician avoid confusing IOCR2 620-022-000-112 with a field I/O card?
During a IOCR2 620-022-000-112 review, use the physical rack position and connector function: IOCR2 sits on the communications side behind the paired CPUR2, while field I/O cards carry the measurement terminations. The external protocol cable should follow the IOCR2 path.
