  1. Specification Of Scada Systems

    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?
  2. Specification Of Scada Systems

    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.
  3. Control Valve

    We haven't yet picked a brand yet. When we do will tell you about it. Thanks
  4. Control Valve

    Thank you. Makes sense
  5. Control Valve

    It is a normal flow control valve.
  6. Control Valve

    Thank you. I am guessing with a three-way valve there will be three 24v DC digital output for position 1, position 2 and close  
  7. Control Valve

    Hi, Please I am new to PLCs & SCADA. I will appreciate if someone can explain what it means by The inlet valve will be actuated by the SCADA  system via two 24V DC digital outputs. Why is it using two 24V DC digital output. Is this because it is a solenoid two way valve?   Thanks
