Defining SP-SPDVOTE Channel Blocks

The SP - SPDVOTE channel block accepts multiple inputs (PV1, PV2, PV3, and PV4) from the SP -

SPEED block of the parent IOM to compute Voted PVs (VOTPV1 and VOTPV2) and Voted ROCs

(VOTROC1 and VOTROC2). It generates alarms such as over speed/acceleration, for the Voted PV

or ROC.

ATTENTION

You are recommended to use the DATAACQ block for generating alarms such as over speed,

over acceleration, under speed, and under acceleration, using the SP_SPEED and SP_

SPDVOTE PV parameters.

The Voted PV can be connected to

l any function blocks that are running in C300 - 20mS CEE Controller, or

l OP parameter of SP - AO channel in the same SPM.

The SP-SPDVOTE channel allows you to configure all flags for generating alarms or processing

control logic.

The output pins can be connected to the interlock parameters of the parent IOM's SP - DO

channel and it can be used as a trip signal.

ATTENTION

SP_SPDVOTE block pins PV1, PV2, PV3, and PV4 accept connections only from the PV pins of

local SP_SPEED channel block pins. All other connections to PV1, PV2, PV3 and PV4 pins of

SP_SPDVOTE logic block are blocked.

l Voting Logic Algorithm Execution

10.22.1 Voting Logic Algorithm Execution

There are two different pairs of output.

l Voted PVs (VOTPV1 and VOTPV2)

l Voted ROCs (VOTROC1 and VOTROC2)

These output are obtained by processing the inputs received from the SPEED block. The inputs

are processed using the voting logic. This block supports two groups of voting logic.

l Voting Logic Group 1

l Voting Logic Group 2

A maximum of 3 channels can be configured as part of each voting group. The selection is based

on GRPxVOTCHENB[1..4], where x = 1 or 2.
