IS200VCMIH1BCB

Product Description

Described as a Bus Master Controller the IS200VCMIH1BCB model is used for communications between I/O boards and the primary controller. The VCMI model was designed with the Texas Instruments TMS320C32 DSP (Digital Signal Processor). The primary hardware features of the VCMI Controller are a single parallel port, a processor watchdog timer, a power system monitoring function, and more. More hardware features can be found on page thirteen in chapter nine of the GEH-6421C Volume II Mark VI System Guide. 

The main location of the IS200VCMIH1BCB model is in the first slot of the VME rack, whether the VME rack is a thirteen or twenty-one-slot rack. The VCMI card is primarily used for the following interior communications such as the primary processor card, I/O in back <P> Protection Modules, I/O cards that are within the same card rack as the VCMI card, I/O in other Control Modules used in TMR control configurations, and I/O cards that can be contained in expansion I/O racks known as Interface Modules.

Please note that the primary processor card of the module will implement the majority of the application software at a rate of ten, twenty, or forty milliseconds which depends on the application requirements. 

Depending on the chosen system in which the IS200VCMIH1BCB model is being used in the input data collection differs between the TMR and Simplex systems. When the VCMI card is being used in a Simplex system, the VCMI card will collect data from the other I/O boards and will transfer the collected input data to the control module over the IONet. To find out about how the input data collection is used in a TMR System refer to page fourteen in chapter nine of the GEH-6421C System Guide.
