DS200SNPAH1A

DS200SNPAH1A is a Protocol Interface Daughter Board manufactured and designed by General Electric. The SNPA connects the DSPC board and the Series 90-30 PLC via RS-232C and isolated RS-484 serial communication. This PLC communicates via a Series Ninety Protocol (SNP) bus. The SNPA is a DSPC daughterboard that is not found in LCIs equipped with Innovation Series Controllers.

Functional description

• It is used in conjunction with the DS200DSPC Digital Signal Processor Control Motherboard. The board is installed in the VMEbus rack with the SPC and the ADMA Analog-to-Digital Module.
• This model's primary function is to provide isolated RS-484 and RS-232C communication between the attached DSPC board and the Series 90-30 PLC model. The control cabinet is also included with the SNPA model.

DS200SNPAH1A Features

• The LCI with Innovation Series Controller differs greatly from the PLC-based LCI Controller in that it eliminates the need for it. This model will never be used with the LCIs found in the Innovation Series Controllers.
• The communications bus on the board is of the Series Ninety Protocol (SNP) variety.
• The SNPA daughterboard is not required by the LCI with an Innovation Series Controller, whereas the SNPA board is required by the LCI with a PLC.
• On the SNPA board, there are two protocol selections: 1, which allows the Series 90 Protocol to be enabled, and 0, which disables the board.
• The GEI-100226 User's Guide, which is a part-specific manual for the SNPA, is the best manual to use with this board.
