About the IS215VCMIH2C

• The IS215VCMIH2C is a VME Communications Board by GE for the Mark VI Turbine Control System Series.
• This series manages gas, steam, and wind turbine automated drive assemblies.
• It's a revised version (C-rated functional product revision) of the IS215VCMIH2 parent board, altering performance without aesthetic changes.

Hardware & Functionality

• Functions as a VME Bus Master Controller, critical for system operation.
• Enables communication among I/O cards (VME backplane, expansion racks, backup/triple redundant modules) and the main processor module.
• Acts as the communication interface to the IONet system control network.
• Front faceplate features:
  • One RS-232C Serial port (D-style plug connector).
  • Three IONet 10Base2 Ethernet ports, each with TX/RX/CD LED indicators.
  • Additional LED indicators: Status, Fail, Run, and 1,2,4,8.
  • A reset switch (push button).
• Communicates execution data with main processor modules via application software.

Criticality & Information

• Critical component: Spares are advisable to prevent downtime.
• Functional product number (IS215VCMIH2C) acts as a strong source of hardware info, coding for:
  • IS215 series tag: Special Mark VI assembly, conformal PCB coating, and other hardware traits.
  • C revision: Indicates functional changes.
• Despite GE's copyright efforts, instructional materials are relatively available online.
