The IS210BPPBH2C Dual-Port Processor Board

The IS210BPPBH2C (full revision IS210BPPBH2CAA) is a BPPB I/O pack processor for GE's Speedtronic Mark VIe controls, described here as a dual-port board. That label refers to the two network ports every BPPB processor carries: they connect the I/O pack to IONet, the Mark VIe I/O network, with the second port providing a redundant path so the pack stays reachable if one leg drops. Beyond the network interface, the board is the compute core of the pack — it seats on an application-specific acquisition board, runs the pack's code, and shuttles I/O between the field terminations and the controllers.

Like the other BPPB revisions, it carries two status LEDs and an on-board temperature sensor whose reading is logged and can raise a diagnostic alarm. The H2C is a later revision within the BPPB group than the common H2B; treat it as a revision difference rather than a different type of board.

What Looks Like a BPPB Failure but Isn't

The dual-port network interface is a good place to begin, because network problems are the faults most often blamed on the processor:

• IONet legs. If the pack drops off the controller, test both ports and both network branches before condemning the board — a single failed cable, switch, or leg can look like a dead processor while the board is fine.
• Power feed. The pack is powered through its acquisition and terminal board, so confirm the supply is present.
• Acquisition board and field side. Wrong signals with a communicating processor point to the board underneath, its fuse, or the field wiring rather than the BPPB.
• Heat. A tripped temperature alarm usually means airflow or a fan, not the processor itself.
• LEDs and logs. Read the two LEDs and the ToolboxST alarms against GEH-6721 before acting.

On a TMR machine the redundant packs map to the <R>, <S>, and <T> controllers; confirm which core voted out so you replace the right one.

H2B vs H2C: Reading the IS210BPPBH2C Suffix

The number breaks into the assembly designator (IS210), the functional acronym (BPPB), a hardware group (H2), and a revision suffix; this unit's full code is H2CAA. H2C is simply a later revision than H2B of the same functional board, so match the acronym and group first, then get the revision as close as your spares allow. Mark VIeS safety processors carry an S-group suffix, which marks this H-group board as a standard pack. Our GE Speedtronic Part Number Decoder details each field of the number.

Companion Boards and TMR Behavior for the BPPB

The BPPB supports gas- and steam-turbine controls and pairs with a range of acquisition boards to build different I/O packs. Its successor is the BPPC, which can share a TMR system with BPPB packs; a BPPB-to-BPPC swap is normally handled by auto-reconfiguration, useful to know as BPPB revisions become harder to find.

How to Prepare Your Quote

To match the right BPPB revision to your pack, please provide:

• The full part number with suffix (IS210BPPBH2C or IS210BPPBH2CAA).
• The revision on the board label, with a photo of the label if you can.
• Turbine model and whether the platform is Mark VI or Mark VIe.
• Quantity and how urgent the repair is.
