Description
CmpIoMgr configuration types, ConfigAccess, Parameters and help functions: manages the I/Os in the application.
Contains functions and function blocks which are required matching
IEC61131-3 as standard POUs for an IEC programming system. Link the standard POUs to the project (standard.library).
Analog Monitors, BCD Conversions, Bit/Byte Functions, Controller
Datatypes, Function Manipulators, Mathematical Functions, Signals.
SysMem, Standard. These functions facilitate communications between specific devices. Most of them are dedicated to Modbus exchange. Communication functions are processed asynchronously with regard to the application task that called the function.
Contains functions and variables to get information and send commands to the controller system.
Allows organization of data to optimize exchanges between the
Modbus client and the controller, by regrouping non-contiguous data into a contiguous table of registers.
