Types of libraries

Control FPWIN Pro7 offers four types of manufacturer's libraries:

1. IEC standard library:

   Contains a collection of standard functions and function blocks as defined by IEC 61131-3, e.g. data type conversion functions, arithmetic functions, bit shift functions, comparison functions, bistable function blocks, timers, or counters. See also advantages of IEC instructions.

   e.g. ADD, CONCAT, MOVE

2. FP library:

   Contains the complete FP instruction set, which includes FP and F instructions. FP instructions were developed for the FP7 but are supported by the other FP series PLCs. Many F instructions provide similar functionality but operate on different data types. Overloaded FP instructions combine these instructions, making it easier for users to select the appropriate instruction.

   • FP instructions: e.g. FP_MOVE_BLOCK, FP_BAND

   • F instructions: e.g. F0_MV, F159_MTRN, F171_PulseOutput_Home

3. FP pulsed library:

   Contains the complete set of P instructions. P instructions correspond, with regard to their function, to the F instructions; however, they are executed only in case of a rising edge. P instructions are only available for the PLC types FP2/2SH, FP3/5, and FP10/10SH. If you require a P instruction, select [Insert P instruction] from the Instructions pane.

   Example: e.g. P0_MV

4. FP tool library:

   Contains advanced address, information and copy functions, which facilitate programming. Tool instructions are available for all PLC types.

   For advantages of tool instructions over F instructions, see the general information on high-speed counter and pulse output instructions.

   Example: Adr_Of_Var I, Unit_AnalogInOut_FP0_A21, HscControl_CountingDisable, Pulse_TargetValueMatch_Reset
