Step 3.5. Configure the Execution Sequence group

You can configure the Output Modules at the site level to execute a set of Function Blocks or to execute custom BCE scripts that you created.

Use the following fields to configure the execution sequence.

 

Field

Description

1

Ready Point

Name of an analog CIMPLICITY Point that will be updated to indicate that the automation equipment is ready for a decision to be executed.

 

 

The RCO runtime system will wait until the Ready Point is updated to the value specified in the Ready Value field before output script for a selected decision is executed.

2

Ready Value

Value written to Ready Point to indicate that the automation equipment is ready for a decision to be executed.

3

Done Point

Name of an analog CIMPLICITY Point to be updated when a decision has been executed.

 

 

When the RCO runtime system has completed the execution of the output script associated with the selected decision, it updates the Done Point to the value specified in the Done Value field.

4

Done Value

Value written to the Done Point by the RCO when the decision output script has been executed. The value entered must be numeric.

 

 

To insure that RCO recognizes an updated Done Point:

  1. Configure a site with a Done point.

When the Done value updates to a new value the site is done.

  1. Change the point to a value other than the Done point value either through a script or manually.

Result: RCO notifies you the next time it sets the point to the Done value.

 

 

 Important: If an updated Done point value is the same as the previous value, RCO will not know that the value is updated. Therefore, a decision may time out waiting for a Done point even though the point is set to the correct value.

5

Sync Val Point

Name of a point that will be updated to indicate that a decision has been successfully completed.

 

 

An RCO waits for this point to be set to the value specified in the Verif. Value.

6

Sync Val Value

Value to be written to Verification Point by the automation equipment or other process to indicate that the decision execution has been successfully completed.

 

 

The site will stop all execution until the value indicates that the decision has been completed.

7

Sync Val Timeout

Value of a time out in seconds after which the:

 

 

  1. Get Sync Val fails and the

  2. Site is disabled.

A value of 0 makes the site wait indefinitely for the verification point to get set to the verification value.
