8.14 API, Application Programmers Interface
The API, Application Programmers Interface, is an interface to the PowerMACS TC system that makes it
possible to access data in the PowerMACS TC from, externally written, custom applications.
The PowerMACS API is a software library that serves as the interface between the custom application and
the PowerMACS TC. This means that it exports a number of functions that the custom application can call
in order to access the PowerMACS target system without needing to know the details on how they are
performed. Today the PowerMACS API exports functions for performing the following tasks:

Read and write PLC signals from/to the PowerMACS station PLC

Read cycle data from the PowerMACS system

Read events from the PowerMACS system

Read traces from the PowerMACS system

Read and write complete setups from/to PowerMACS system

Read or write individual parameters in a setup stored in a PowerMACS system
