The settings listed below apply to data types connected to the CDF time series resource type.
In InField, the settings on the Trends tab are visible on the Trends page from the sidebar or on the Overview page.
Trends are identical to time series in CDF. Some tags may have many connected time series, but not all are equally important. In this section, you decide which time series to show as the default and which time series you want to filter out.
OPC UA time series
InField can display value ranges and alarm limits for time series if CDF streams data from the OPC UA protocol. If you want to show the range of a time series, the time series must have the following metadata field:
You'll see the value range on the Time series card in the sidebar on the Trends page.
OPC UA time series alarm limits
Alarm limits are displayed as labels on the time series on the Trends page and listed on the Properties card on the Overview page. The alarm limits are sorted as LL (Low, Low), L (Low), H (High), and HH (High, High).
If you want to add alarm limits for time series, the OPC UA time series must have an OPC asset that's a child of the equipment asset with the same name. For example:
To show alarm limits, these metadata fields must exist on the OPC UA child asset:
LO_LIMx.Valueindicates the value of the alarm limit.
USE_LIMx.Valueindicates if the alarm limits are in use or not.
Alarm limits and value ranges are available on both desktop and handheld devices.
InField doesn't display alarm limits and value ranges with no value.
