I/O type for Instrument Index

[JrEngineer]

Is the I/O type for the below correct?

1. Motor Operated Valve (MOV)

Tag Number Loop Instrument Type I/O type System
MOV-001 M-001 Motor Operated Valve - -
HS-001 M-001 MOV Local/Off/Remote DI SIS
ZA-001 M-001 MOV Battery low alarm DI PCS
ZSC-001 M-001 MOV Limit switch close DI SIS
ZSO-001 M-001 MOV Limit switch open DI SIS
HSX-001 M-001 MOV Local Handswitch - -



2. VFD

Tag Number Loop Instrument Type I/O type
HS-001 V-001 HOA Switch DI
XC-001 V-001 Pump Start DO
XS-001 V-001 Pump Run Status DI
XY-001 V-001 Permissive DI

What is the I/O for Accelerometer?

[JrEngineer]

Attached are the typicals for the MOV and VFD. Is the I/O type correct? Is that enough information for the Control system vendor or do I have to include anymore?

if not connected with Bently system ( proprietary system) you can ask vendor to provide 4- to 20 mA i*e Analog input.

Why the following signals send to SIS instead of PCS?
HS-001 M-001 MOV Local/Off/Remote DI SIS
ZSC-001 M-001 MOV Limit switch close DI SIS
ZSO-001 M-001 MOV Limit switch open DI SIS

I understood that signal sends to SIS shall be for trip and shutdown functions. Pls. correct if I'm wrong.
