Apply a Max Wait Time to a list

00:03

Within the Push to List activity,

00:05

you can use a Max Wait Time to control the duration of time that values remain on your List

00:11

and what happens to them once they are released from the List.

00:14

Use Max Wait Timer sets a maximum duration for a token to wait on the List before being released.

00:21

Keep On List On Early Release ensures that a token remains on the List even if the wait timer has fired.

00:28

Here, you see some information about the Max Wait Timer function, as well as a process flow to illustrate these functions.

00:37

Click Push to List.

00:39

In Quick Properties, select Use Max Wait Timer,

00:44

then set the maximum Time the value should remain on the List before it is released—here, 10 seconds.

00:52

Or, expand the Time drop-down to choose from alternate options.

00:58

On Wait Timer Fired is currently set to do two things—set a label and release the token.

01:06

To view these settings, click Edit Properties.

01:12

Expand Set Label to see that the label is currently set to “failed”, with a Value of 1.

01:20

Next, expand Release token, where the release Destination is set to 2.

01:28

This means that when a value is on the list for more than 10 seconds, it is not pulled from the list and sent to Connector 1 on the Pulled path.

01:36

Instead, the token is assigned a failed label and sent to Connector 2 on the Failed path.

01:44

Open On Wait Timer Fired again and click Add.

01:50

Here, you can select other actions to take place when the Wait Timer fires.

01:56

Next, select Keep On List On Early Release.

02:02

This option allows you to keep values on the list even if the Wait Timer is fired.

02:08

For this example, deselect this option.

02:13

In List Quick Properties, open View Entries.

02:20

When the simulation is Run at an accelerated speed, you can see that several tokens proceed to the Failed path,

02:28

because they were on the list for more than 10 seconds without being pulled.

02:33

Click these tokens, and, in Properties, you see the failed label with a value of 1 on each.

02:42

The simulation is continued until tokens proceed to the pulled path.

02:48

Click one of the pulled tokens to see that the token label corresponds to the puller token, since it was pulled from the list successfully.

02:57

Now you know how to use the Max Wait Timer to control the duration that values remain on your List,

03:04

as well as where and how tokens proceed when released.
