Instructions:  
The table below contains some samples links of inputs and outputs in operations, functions and function blocks, as well as word connections of the variables.
 

No.	Sample links:
1	Linking inputs and outputs of the REAL, INT and DINT types The following functions are available for linking analog inputs and outputs of the REAL, INT and DINT types in operations, functions and function blocks: The load and transfer statements in the STL editor The "MOVE" function in the LAD and FBD editor. The example illustrated below contains a conditional connection of two variables. The marker double-word MD10 only receives the value from the temporary variable "X_Real_1", when the value from "X_Real_1" is greater than or equal to the value from the temporary variable "X_Real_2". This value is then transferred to the input "Input_1" (Type: REAL) of function FC1. Example of display in the FBD editor with the function "MOVE": Fig. 01 Example of display in the STL editor with the load and transfer statements: Fig. 02
2	Word connections The statements UW, OW, XOW, UD, OD, XOD link the value in Accu 1 with a constant or the contents of Accu 2 bit for bit. The link can be word for word or double-word for double-word. Fig. 03 The following alternatives are available for doing so: You can enter the operand in HEX format (for example OW W#16#AAAA).  The two binary constants are first loaded into ACCU 1 / ACCU 2 with the load command and the linked with the link command without operand (e.g. OW). Fig. 04 shows the word connection with a constant (Network 1) and with the contents of Accu 2 (Network 2). Fig. 04 Note: In the case of bit-for-bit links of WORD or DWORD constants with the operations UW, OW, XOW, UD, OD and XOD the binary constants (e.g. OW 2#1010101010101010) are not supported as operand.
