Hermetry 2.0 went out yesterday (2.0.0 in the changelog, 26 August). Kuray has posted about keeping organisations apart and the hosting regions. This post is about the part I work on.
2.0 has SCADA process screens. You build them from a symbol library and draw them in 2D, and in 3D too. The same release brings what those screens sit on: devices over MQTT and HTTP with device profiles, telemetry with history and rollups, dashboards with charts, tables, maps and gauges, alarms with five severities, acknowledgement and notifications, and rules and flows that act on live data.
Where to read first:
- SCADA, how drawings, symbols and views fit together
- The SCADA designer for 2D drawings
- 3D views and The 3D designer
I will put some of the screens I have drawn in Show and tell over the next weeks. If the designer does something you did not expect, ask here and I will look at it.
Is this in every plan? I can see Dashboards but there is no Process Diagrams entry in our menu.
The SCADA and 3D modules belong to the IoT add-on, so the menu entry stays hidden until your organisation has it. Plan & Billing shows what you have. With the add-on you get the designer and the core symbol set; the industry symbol libraries are bought one by one on top. Details in Plans and the IoT add-on and Symbols and industry packs.
Drew a small booster station this morning. Placing symbols and pipes went fast. What threw me: there is no field anywhere in the designer to say which device value a pump shows. Am I blind?
Not blind, it is on purpose. The drawing holds no device data. After you save it, you attach it on the device’s (or the site’s) Views tab and connect each symbol there with Edit symbols. That way one drawing can serve many stations and each keeps its own connections.
Shortcut if you control the firmware: keys named <symbol id>.<field>, for example pump1.running or t1.value, connect by name without any clicking. Binding symbols to live data
Found it. Changed the pump ids under Advanced so they match our keys and 9 of 11 symbols connected on their own. The other two are valves that report closed as 1, I inverted those with an expression.
Any ISA-101 style option? Green on every running motor wears operators out on a 12 hour shift.
Yes, Calm look. Click on the empty canvas so nothing is selected, and the inspector shows the settings for the whole drawing. With Calm look on, running parts are drawn in plain ink and only warnings and alarms get colour. It is off by default.
