What this block does
Associates the drawing's point and command mappings with the selected IED configuration revision.
A simple example
In a substation control building, the station controller receives bay information and forwards an operator's selected command to the correct bay device. Device feedback confirms whether the intended result actually occurred. For this reference, the drawing identifies “Drawing signal map” at the input and “Configuration revision link” at the output. The referenced revision must match the installed system.
What the drawings help you do
Start at the named input: Drawing signal map. Identify its source device or document and the state represented on the drawing. Follow the named output: Configuration revision link. Cross-reference its destination and separate the command from confirmation that the equipment responded.

What it represents
Associates the drawing's point and command mappings with the selected IED configuration revision. Station automation collects measurements and statuses and issues assigned commands through defined authority paths. A communicated point has a value, quality and equipment identity; it should not be treated as an unexplained contact.

Document the point mapping, source, destination, command authority and failure behavior. A communication interface block explains information flow and does not certify network security or control-system availability. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.
How to read it
- Start at the named input: Drawing signal map. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Configuration revision link. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- The referenced revision must match the installed system.
- Document the point mapping, source, destination, command authority and failure behavior. A communication interface block explains information flow and does not certify network security or control-system availability.
Information to show or reference
- Label the source and connection reference for drawing signal map.
- Identify the destination and defined state of configuration revision link.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: The referenced revision must match the installed system.
A distinction that matters
The referenced revision must match the installed system. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.
