Setting Data Items on an Asset Using ThingWorx Composer
Support for egress allows you to set data items (properties) on an Axeda asset by updating its corresponding Axeda entity in ThingWorx.
 |
As of v.2.1.0 of the Axeda Compatibility Package and v.9.1.0 of ThingWorx SCM Utilities, a Set Property instruction is provided so that you can set a property value for multiple devices using an instruction-based package. You can have one or more of these instructions in a package. Refer to Using the Set Property
Instruction for details.
