M218 Read Functions

 

Overview

This section describes the read functions included in the M218 PLCSystem library.

In many cases, similar information returned by these functions can also be obtained through System Variables. System Variables are common across the control platforms, and therefore it is recommended to use them where possible for the portability of your applications. The information contained in the System Variables is often similar, though not always exactly the same as that returned by the functions. If you are replacing these functions in your program to favor the use of System Variables, be sure to understand the differences in the information offered.

The following function descriptions indicate when a System Variable is available for similar information.
