Data extension identifier | System text (without spaces and diacritics - i.e. national dependent characters). It is used for unambiguous identification of data extension in data item (e.g. in the Extension method).
The default value is "opcc". |
---|---|
Target object (PmaOpcDaClientGroup) | Path to the target object of appropriate type, in which the data variable must be registered. The object can be selected also by the button on the right. By this selection the OPC server, refresh rate and other parameters defined in the PmaOpcDaClientGroup object can be defined.
Macro expression can be used for input, the result must be a NON-LOCALIZED path to Pma object (it is evaluated after the application is launched). |
ItemId | Text address/identifier of the variable in the OPC server. The address can be entered either manually or it can be selected from the window "Viewing the OPC server address space" that can be opened by the button right from the input. But the selective window can be opened only if the OPC-DA server is installed and if it supports the selection.
This configurator sets the initial value of the ItemId property. Macro expression can be used for input (it is evaluated after the application is launched). |
AccessPath | Access path to the variable in the OPC server. The value can be empty usually.
The path can be entered either manually or it can be selected from the selective window that can be opened by the button right from the input. But the selective window can be opened only if the OPC-DA server is installed and if it supports the selection. This configurator sets the initial value of the AccessPath property. Macro expression can be used for input (it is evaluated after the application is launched). |
Value recalculation | If checked, then the received and sent value will be recalculated by the PmValue = k/d * CommValue + q formula, where PmValue is the value in the PROMOTIC system, CommValue is the value from the communication, k,d,q are the recalculation constants defined in the configurator.
Caution: Vhen sending the value with conversion, some inaccuracy may happen and therefore the PmValue sent could differ from the PmValue received. For example for the conversion of PmValue = 1000 * CommValue and if CommValue is the value on 1B (Range 0-255), then when sending the PmValue=2008 the CommValue=2 is sent. If the CommValue=2 is received, then the PmValue will be 2000. |
