Description
Product Introduction
GE IS215VCMIH2CC is the VCMI (VME Communication and Control Interface) bus master controller in GE’s Mark VI and Mark VIe turbine control systems, serving as the central processor that manages VME backplane communication, I/O board coordination, and IONet network interfaces for primary and redundant control.xm-dcs+1
This 6U VME card features a 32-bit TI TMS320C32 DSP, three 10Base2 IONet ports (R, S, T) for TMR architectures, 4 MB Flash for firmware and topology storage, and comprehensive power bus monitoring, making it the core controller for complex gas and steam turbine applications.xm-dcs+1
Frequently Asked Questions
Q: Can I hot-swap the IS215VCMIH2CC?
A: No. The VCMI is the primary controller in the Mark VI VME rack; it is not designed for hot-swap insertion. You must de-energize the entire VME chassis or follow the strict offline replacement procedure in TMR systems (inhibit control, remove one controller at a time, re-energize, and verify voting) to avoid tripping the turbine or losing control.xm-dcs+1
Q: Is the IS215VCMIH2CC obsolete? Are there direct replacements?
A: Yes, the VCMIH2CC is effectively obsolete in new GE production. Direct replacements are other VCMI variants (e.g., IS215VCMIH2C, IS215VCMIH2CB) or upgraded Mark VIe controllers (e.g., VCMIe), but verify mechanical envelope, IONet port count, Flash memory size, and ToolboxST compatibility before swapping.xm-dcs+1
Q: Will I lose my turbine control program when replacing this board?
A: Yes, if you do not back up first. The control logic, topology, and parameters reside in the VCMI’s Flash memory and are managed via ToolboxST. Before replacing the IS215VCMIH2CC, you must upload the full application from ToolboxST to a PC, then download it to the replacement controller after installation and hardware configuration (DIP switches, jumpers).xm-dcs+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original GE packaging, never installed) or tested used units with 12–24 month warranty. Genuine GE factory-new IS215VCMIH2CC boards are rare. Request photos of packaging, revision labels (H2CC/H2C), and serial numbers for audit.
