Frequently Asked Questions about DS200SNPAH1A

What type of communication bus does the DS200SNPAH1A use?

The DS200SNPAH1A board uses a Series Ninety Protocol (SNP) type communications bus.

Is there a difference in using a PLC-based Load Commutated Inverter (LCI) instead of an LCI with an Innovation Series Controller?

Yes. The LCI with an Innovation Series Controller completely eliminates the use of the SNPA daughterboard whereas the PLC-based LCI will still need the SNPA board. 

What manual/manuals can I use with the DS200SNPAH1A model?

The GEH-6373 Load Commutated Inverter, User's Manual has limited information on the DS200SNPAH1A board but it can be used if some information about potential connections is needed. The best manual to use with this board is the GEI-100226 User's Guide which is a part-specific manual for the SNPA. 

What are the SNPA protocols that can be set on the DS200SNPAH1A board?

There are two protocol selections on the SNPA board, one being 1 which allows for the Series 90 Protocol to enable, and 0 which means that the board is disabled. 

Product Description

General Electric LS2100 Series Model DS200SNPAH1A is an SNP Protocol Interface Daughterboard used with the DS200DSPC Digital Signal Processor Control Motherboard. The board is mounted in the VMEbus rack alongside the SPC as well as the DS200ADMA Analog-to-Digital Module. The primary function of this model is to provide an isolated RS-484 and RS-232C communication between the attached DSPC board along with the Series 90-30 PLC model. 

The DS200SNPAH1A model is configured with the control cabinet as well. The LCI with Innovation Series Controller is vastly different from the PLC-based LCI Controller as it diminished the need for this controller. This model will under no circumstances be used with the LCIs within the Innovation Series Controllers. 

This model is available on the market in both new and used surplus, as well as refurbished conditions. This model can be found here at AX Control Inc and comes under our three-year warranty, to inquire about the availability of the DS200SNPAH1A feel free to contact us by phone number or email during normal business hours of Monday through Friday 8 a.m to 5 p.m. For installation instructions please refer to the GEH-6373 manual or the GEI-100226 manual.
