Specification Of Scada Systems

4 posts in this topic

Hi,

Please I am new to SCADA system and currently doing a specification document for my university project. I am doing it for a SCADA system and need someone with knowledge to review what terms I have used for the sections I have.

For the System Operational Functional Requirements section, I wrote

Fire System Requirements 
The SCADA system will perform monitoring of the Fire Main Inlet Valve. The following status of the Inlet Valve will be monitored, logged and displayed by the SCADA:
• Inlet Valve Position
• Inlet Valve state (Open / Close)
• Inlet Valve Local Control state
• Inlet Valve Fault(Neither Open or Closed)
• Pressure Switch
• Flow Switch

The SCADA system will perform control of the Fire Main Inlet Valve. The Inlet Valve signals to be driven are as follows:
• Inlet Valve Open Drive
• Inlet Valve Close Drive

 

For the System Input and Output Requirements section, I wrote

The SCADA system I/O with the Fire System will allow:
1) Alarm and status information of the system to be monitored, logged and displayed at the SCADA Clients including:
a) Inlet valve position; 
b) Inlet valve alarms;
c) Inlet valve status;
d) Pressure switch status;
e) Flow switch status. 

2) Control of the system by operators at the SCADA Client including:
a) Inlet valve position; 

 

Please I would appreciate if someone could help and evaluate the terms I have used such as 'Status', 'Position' 'State' and others and to correct me if I wrote it wrong or if there are better terms to use or better ways to structure my information.

Is the inlet valve a manually operated valve supposed to always be open under normal conditions ?

If so, I guess the only interesting position would be "Valve open".

If not open you should set an alarm, "Inlet valve not open".

Is this for a low pressure sprinkler system, roughly 6-8 bar ?

Hi,

This is for an actuated valve, that will be controlled to open and close by an operator. Yes it is for a sprinkler system.  Do you think the way I wrote it is fine or I can word it better?

It seems ok to me, but what do you mean with "c) inlet valve status" ?

Is it that the valve is in local or remote (auto) control ?

Just a nosy question since I used to work with high pressure water mist sprinklers.

Is it an open nozzle system or is it a bulb nozzle system ?
