M_In/M_Inb/M_Inw
[Function]
Returns the value of the input signal.
M_In : Returns a bit.
M_Inb : Returns a byte (8 bits).
M_Inw : Returns a word (16 bits).
[Format]
Example) <Numeric Variable>=M_In(<Equation>)
Example) <Numeric Variable>=M_Inb(<Equation>)
Example) <Numeric Variable>=M_Inw(<Equation>)
[Terminology]

1 M1=M_In(0)
2 M2=M_Inb(0)
3 M3=M_Inb(3) AND &H7
4 M4=M_Inw(5)
[Explanation]
(1) Returns the status of the input signal.
(2) M_Inb and M_Inw will return 8- or 16-bit information starting from the specified number.
(3) Although the signal number can be as large as 32767, only the signal numbers with corresponding hard-
ware will return a valid value. Value for a signal number without corresponding hardware is set as unde-
fined.
(4) This variable only reads the data.
Specifies the numerical variable to assign.
Enter the input signal number. 0 to 32767 (Theoretical value)
0 to 255 : Standard remote inputs (Normally 32 points. 0 to 31)
900 to 907 : Hand input.
2000 to 5071 : Input signal of PROFIBUS.
6000 to 8047 : Remote input for CC-Link.
' M1 will contain the value of the input signal 0 (1 or 0).
' M2 will contain the 8-bit information starting from input signal 0.
' M3 will contain the 3-bit information starting from input signal 3.
' M4 will contain the 16-bit information starting from input signal 5.
