Selection Guidelines
-
When to choose:
-
New Mark VIe installations requiring the latest firmware (PR2)
-
Upgrades from older WETA/WETB boards seeking PR2 performance
-
Cybersecurity-conscious installations requiring intrusion detection
-
ControlST v8.0+ environments
-
-
Protocol Selection: Use I/O Net for internal; Modbus TCP for DCS; OPC UA for IIoT; DNP3/IEC 61850 for utilities.
-
Cybersecurity Configuration: Configure firewall, IP filtering, TLS 1.3, and intrusion detection per plant security policy.
-
Firmware: PR2 is pre-loaded—no field update required.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v8.0 or higher for full PR2 features.
Operational Precautions
-
Wiring: Use shielded CAT5e or CAT6 cables; avoid routing near high-power cables.
-
Port Status: Link/Activity LEDs—green for link, amber for activity.
-
Redundancy Testing: Simulate port failure to verify <5 ms failover.
-
Cybersecurity: Configure firewall, TLS 1.3, and intrusion detection before plant network connection.
-
Fault Log: Access 2000-event log via Toolbox ST.
-
Packet Capture: Use sparingly; download for off-line analysis.
-
Coating Care: Use GE-approved cleaner; inspect annually under UV.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware: Do not downgrade—PR2 is factory-loaded and validated for ControlST v8.0+.
-
ESD: Handle by edges only with grounded wrist strap.
-
Storage: Anti-static bag with desiccant at –40 to +85 °C; rotate every 3 years.
