Instance parameters stores information and also the configuration about an instance such as name, address, what Connector to use for its connection. The parameters also contains defaults that are being used through out all its items unless individually specified per item such as read settings and storage settings.
Connector parameters
For connector specific parameters check out their individually articles under their sections
Empty parameters
SIA allows properties not to be filled so ensure that this the case for the given instance. This could for instance be the address or more specific Connector parameters that might be needed to establish proper connection to the instance.
General
The general parameters are everything that relates to the instance such as address and description.
| Parameter | Description |
|---|---|
| Connector | Select which Connect interface to communication to this instance through. Note: the parameters in Connector setup will change according to which Connector is selected. |
| Name | Name of the instance. E.g. "Bottle machine 1" or "Cloud backend" |
| Address | Address of the instance. This can for example be IP, http & serial address |
| Unique ID (UID) | Unique ID (UID) is a unique reference to an item or instance. The UID can be referred to in various places such as parameters, mappings and scripting by calling it by %UID%. E.g. calling the name of an instance where BOTTLE_MACHINE is the UID is done by %BOTTLE_MACHINE.NAME%. |
| Description | Description of the instance. E.g. "Bottle machine in Aarhus, Hall 5" |
| Enabled | Enable or disable the instance. |
Setup
The setup parameters are parameters that relates to reading, storage and how SIA should handle it. These parameters will also be used as the default for the items when you are creating items under the instance.
| Parameter | Description |
|---|---|
| Mode | Selects the instancedefault mode for its items: Gateway: No history for data are stored on SIA |
| Read interval | The default read time for each item associated with the instance. This can also be set individually for each item on the instance. |
| Store time | The default store time for logged data on the items on the instance. This dictates how long the data is stored. This value can also be set individually for each item. Only applies in Logging mode |
| Max samples to store | The default amount of samples to store for a item. While the "Store time" parameter dictates the period to keep data this defines the amount. Only applies in Logging mode |
| Status report interval | SIA reports the status for an instance which contains eventually error messages. This parameter defines how often it should send this status report through a mapping. |
