Data Interrogation Parameters

[IEC870IP] Parameter

Description

Allowable Values

Default Value

ManufacturedIsUTC

Determines if the 56-bit timestamp value received from the device is considered to be UTC time or not.

Note: You can set this parameter for every device connected to a specific port. See Port-specific Parameters.

0 = timestamp is not UTC

1 = timestamp is UTC

0

ManufactureTimestamp

This parameter controls the value timestamp for tags with following addresses:

• D<IOA>
• I<IOA>
• L<IOA>
• F<IOA>
• QD<IOA>

If the parameter is set to 0 (the default), the value timestamp will be equal to the device timestamp, or to the driver manufactured timestamp when the driver receives a value update.

If the parameter is set to 1, every value timestamp will be manufactured by the driver.

Note: You can set this parameter for every device connected to a specific port. See Port-specific Parameters.

0 or 1

0

ReportDoubleDigitalPoint
OnOffStates

When a double digital point is configured using a digital tag, by default it reports double point states as:

• 1 "On"

• 0 "Off"

• 0 "Indeterminate"

• 0 "Intermediate".

If this parameter is enabled, the driver will only report a value update when the double point value is set to “On” or “Off” states.

0 or 1

0

StoreDigitalInQual

Determines if the value of a single or double digital point is stored inside the quality descriptor. This allows a single tag to be used for both value and quality information.

Note: The following information only applies when StoreDigitalInQual is set to 1.

The IEC standards specifies the following for a double-point digital DPI field:

• If DPI=0, the field is
"indeterminate or intermediate"
• If DPI=1, the field is "valid"
• If DPI=2, the field is "valid"
• If DPI=3, the field is "indeterminate"

To determine the value of the DPI from a digital tag (D) and the quality descriptor (QD):

• If QD Bit 1 and Bit 2 are not set and D is 0, then DPI=1
• If QD Bit 1 and Bit 2 are not set and D is 1, then DPI=2
• If QD Bit 2 is set, then DPI=0
• If QD Bit 3 is set, then DPI=3

0 = do not store the digital point in the quality descriptor.

1 = store the digital point in the quality descriptor.

0

UpdateNonTimestampedTagWith
TimestampedData

This parameter determines whether the non-timestamped tag value is updated when timestamped data is received. By default when a timestamped value is received, the values for timestamped and non-timestamped tags will be updated. But in case the parameter is set to 0, only the timestamped tag value be updated.

Note: You can set this parameter for every device connected to a specific port. See Port-specific Parameters.

0 or 1

1

UpdateTimestampedTagWithNon
TimestampedData

This parameter determines whether the timestamped tag value is updated with non-timestamped data. If it is set to 1, the timestamped tag will be updated with non-timestamped data until timestamped data is available.

Note: You can set this parameter for every device connected to a specific port. See Port-specific Parameters.
