Add and connect devices in plant control

Scope

This guide puts the devices of a site on the Plant Control Diagram, with one line for each cable. See How plant control works.

Location

• Path: My Devices, Plant Control System, then the Diagram tab.
• Edit mode: the menu at the top left of the canvas, then Edit.

Permissions

• Add, connect, change and remove devices: Editor, Installer or Full control.

Step 1: Device Points

The system adds a battery and a hybrid inverter on the logger with Enabled set to Enabled. It adds other devices with Enabled set to Disabled.

To add a grid, load, generator, PV meter or switch point:

1. In the Diagram menu, click Add device.
2. Select the Device Type.
3. Type a Device Serial that no other point of that type uses.
4. Click Save.

Step 2: Point Settings

1. In the Diagram menu, click Edit.
2. Double-click the point.
3. On the Basic tab, set Enabled: to Enabled.
4. On a grid or generator point, set Rated Power: to the rating of the connection.
5. On the Max Limit tab, set the Default rule. See Build a rule list.
6. Click Save.

Step 3: Lines

1. Drag from a dot on one device to a dot on the other device of the cable.

Connect each grid, generator and load point to the meter or inverter that measures it.

• Energy meter: input on the left. Connect the supply side to the input, or the reading changes sign.
• Hybrid inverter: grid on the left, load on the right.
• AC Control ATS: inputs on the left, input 1 at the top. Output on the right.

The AC Loops tab then shows each loop that the lines make, with its devices.

Step 4: Battery Link

1. Find the battery serial on the Diagram, for example hv_1 (high voltage, cluster 1).
2. On each inverter or charger of that battery, set Storage Cluster ID: to the cluster number.
3. Click Save.

Step 5: Switch Position

1. On the Basic tab of the switch, set Input ID: to the logger input that reports the position.
2. Set Input Polarity:. Straight reads the switch closed while the input is on.
3. On an AC Control Switch, set Output ID: to the output that operates it.
4. Click Save.

Troubleshooting

• Device not added: Device [...] already exist: a point of that type uses that Device Serial. Type a different serial, then click Save again.
• Device link: [...] already exist!: the two dots have a line.
• can not locate storage data cluster ID: no battery of that voltage has that Storage Cluster ID.

Tips and Gotchas

• To keep moved devices, click the save icon at the top right of the canvas.
