Multistate Row Edit: Input tab

Has Input

Select the checkbox to allow the setting of the multistate point’s current value field.

Use Device Based Questionable DQ

Select to alert downstream krunch processes that, when said processes krunch the current value of the point, freshness should be based on the data quality from the field.

Accumulate Runtime

Select the checkbox to record the time (in hours) that the multistate input has been in the state specified in the Accumulated State field. It indicates the time during the current and preceding hour, day, shift, and month.

Runtime values may be used in a report to determine device maintenance requirements. For instance, pump maintenance is performed when a pump runtime value exceeds the maximum runtime recommended for the month. This could be checked using a Microsoft SQL statement, such as the following:

select name from status where run.month.previous > 1.5

Accumulated State

Select (...) and select the state you want to monitor from the Multistate Message Selector dialog box.

Refer to Select an accumulated state message for more information.

Instrument Failure

Select (...) and select the state you want to assign as the Instrument Failure State from the Multistate Message Selector dialog box.

Refer to Select an accumulated state message for more information.

SOE Point

Select the checkbox to designate the point as a sequence-of-events (SOE) type. When a point is designated as a SOE type, all events and alarms, regardless of what type they are normally, will be SOE type.

SOE points are typically used by the electrical industry, which can receive a very high volume of alarms in a short period. The analysis of events at key points at the millisecond level becomes important. Customers will typically create a separate easy eXtended Operator Station (ezXOS) event screen to isolate these events for analysis.

This feature requires Command Failure Timeout and COS Failure Timeout to be greater than 0.

Input Data Format

Select the multistate subtype used for this point. The choices are the following:

• Enumeration Format. The point reads a register (whole word) from the RTU.

• Bit Format. The point reads up to 8 bits from the RTU. It results in an input of up to 256 states.

• Baseline Configuration. This point uses the Data Format selected on the Main tab.

Bit Pattern Input

Select to open the Multistate Bit Format Input dialog box and configure the input bits.

For more information, refer to Multistate bit format input.

Note: This button will be enabled only in two cases:

1. The Input Data Format on the Input tab is selected as Bit Format.

2. The Input Data Format on the Input tab is selected as Baseline Configuration, and the Data Format on the Main tab is selected as Bit Format.

Enumerated Input

Select to open the Multistate Enumerated Input dialog box and configure Remote Terminal Unit (RTU) register information.

For more information, refer to Multistate enumerated input.

Note: This button will be enabled only in two cases:

1. The Input Data Format on the Input tab is selected as Enumeration Format.

2. The Input Data Format on the Input tab is selected as Baseline Configuration, and the Data Format on the Main tab is selected as Enumeration Format.

Poll Group

A text string that may consist of multiple comma-separated values to define the frequency poll groups to which the point belongs.
