This chapter is concerned with the communication of data. For information about working with 2D graphic objects or pictures, see “Graphic shapes, tools, and commands” on page 639 or “Copy/Paste and Duplicate commands” on page 796.
User interfaces for data exchange
The following sections discuss methods for exchanging data within ExtendSim and between ExtendSim and external applications and devices. Some of these methods (such as Dynamic Data Linking) are specific to ExtendSim, and some (such as ADO) are industry standards for inter-application communication. As discussed below and shown in the table that follows, each method has its own specifications and properties:
