IS215UCVEM01A: UCVE Controller with a Second Ethernet Port

The IS215UCVEM01A is an upgraded UCVE Mark VI controller, adding a secondary 10BaseT/100BaseTX Ethernet port — for EGD and Ethernet Modbus traffic on a separate subnet — to the capabilities of the base IS215UCVEH2. It runs the turbine control application under QNX in the VME rack and is offered here as a used, tested unit.

An Upgrade from the Base UCVEH2

Where the standard UCVEH2 provides a single Ethernet link to the Unit Data Highway, the UCVEM01A adds a second Ethernet interface that the toolbox configures onto its own IP logical subnet. That secondary port speaks EGD and Ethernet Modbus, letting the Mark VI exchange data cleanly with third-party DCS and PLC systems without disturbing the primary UDH network. The controller validates its toolbox configuration against the installed hardware at every power-up, which is how it confirms the secondary port is set up correctly.

VMIC Platform and Faceplate

Like the rest of the UCVE line, this controller is based on a VMIC VME single-board computer; some cards are marked with the underlying board number — the description for this unit references VMIVME-7614-132. When you order, match the full GE IS215 part number rather than the VMIC number, because GE's firmware and configuration are keyed to the IS215UCVE assembly. The faceplate carries status LEDs, a reset button, Ethernet ports and tooling connections, with set screws top and bottom that also serve as handles when the card is drawn from the rack.

Rule Out the Cheap Faults First

Before you replace an IS215UCVEM01A, make sure the controller is genuinely the problem and not the messenger:

• Firmware and application. A mismatched or partial ControlST download or corrupt boot media will fault a healthy board. Reload before condemning it.
• Secondary-Ethernet setup. If the fault involves the second network, check the toolbox subnet and protocol configuration — a setup error mimics a hardware failure.
• VCMI and the VME backplane. The controller reaches the I/O only through the VCMI communication board; a VCMI or backplane fault looks like a controller fault.
• Rack power. A sagging +5 V rail resets the processor.
• Upstream I/O and TMR core. A failed I/O board can report upstream; in a triple-redundant system, confirm which of <R>, <S> or <T> is affected before ordering.

The VCMI communication board is the UCVE's constant partner in the rack, and UCVE is one of several UCVx generations (UCVB, UCVD, UCVE, UCVG). Decode any GE number with the GE Speedtronic Part Number Decoder, review the platform's history in Mark V vs Mark VI: DS200 to IS200, and see related cards in our GE Mark VI IS200 Boards and GE Speedtronic Turbine Control Boards collections.
