Equipment requirements for this example
In this configuration example, we assume that there is monitored equipment with the following requirements:
•In a factory for producing certain parts, five pieces of machinery and equipment are installed for production.
•Each of the five pieces of mechanical equipment is equipped with a contact point for outputting a signal indicating "operating" or "stopped" to the outside.
We will input the "operating" and "stopped" signals from the above machinery and equipment to perform simple operation monitoring.
•The operating/stopped state is indicated by changes in the left indicator light and the background color of the display frame.
•No message display is used.
•Production results will not be imported.
•Displays data on "operating time," "operating count," "stopped time," "count of stoppages," "continuous operating time," and "operating rate."
■ Signals to be captured (examples)
The following contact signals are to be received via downstream devices such as remote I/O.
In this example, all contact signals are taken in through a single downstream device, "Device 1."

The "Device 1" part above should refer to downstream devices such as PLC and remote I/O that are connected from Panel Server. There are various methods for capturing signals from equipment. "Tag registration for collecting operation status" introduces several specific examples of signal capture methods. Please use this as a reference when building an actual system. |
Unit/tag design
Based on the above equipment requirements, a list of signals that the system needs to capture is designed as a "tag list."
■ Tag list (example)
In this example, the unit name for connecting to the downstream device "Device 1" is defined as "U01", and a tag for contact signal import is defined under U01.

The above design documents are called "tag lists" or "device lists." We recommend that you prepare the above information when building any monitoring system using SCADA, not just an operation monitoring system. |
