PROBLEM: RTU’s output 0/1 but require TRUE/FALSE for write

DetailAnalysis — Thu, 14 Feb 2008 21:54:00 GMT

Some digital read writes in RTU's output 0/1 as a value, but require TRUE or FALSE be sent to trigger the write. We have found this to be true in the ScadaPack.

To handle this situation we suggest you use the picklist function to pass the values, and view the raw values as analog not with digital substitution.

This can be done by following the HOWTO document for picklist and using the last example passing a True and False value.

The picklist control allows the control to be set up with predefined values to be sent to the remote device. This restricts to sending only values defined in the picklist. Furthermore labels can be given to picklist values making the selection user friendly.

This is first done by selecting Picklist from your control type:

Then enter the values to pick from separated by comma's:

Then when sending a control you will have those values to select from:

To enter labels for the values separate the label from the value with a pipe character | then use a comma to separate the values as shown:

This will display as shown:

When selecting the actual value will be displayed in the Send Value and will be Read Only:

The PickList also supports sending direct Boolean values:
