Input Terminal; Latch Input Terminal - Mitsubishi Electric MELSEC iQ-R User Manual

Input terminal

Multi function
In the first section in a multi function counter block detail window, two input terminals ("Input 0", "Input 1") are arranged by
default.
They are used to use signals input to a multi function counter block in the hardware logic outline window ("Input 0", "Input 1")
as input signals in the multi function counter block detail window.
Output
The following table shows the output of the input terminal.
Variable name Data type
Input Bit
*1 The input terminals and the input signal event detection blocks are automatically linked in the following combinations, and the links
cannot be deleted.
 "Input 0" terminal (input terminal) and "Input A" terminal (input signal event detection block)
 "Input 1" terminal (input terminal) and "Input B" terminal (input signal event detection block)

Latch input terminal

Multi function
In the first section in a multi function counter block detail window, latch input terminals are arranged by default. For a 16-bit
counter, two latch input terminals ("Latch 0", "Latch 1") are arranged. For a 32-bit counter, one latch input terminal ("Latch 0")
is arranged.
They are used to use latch signals input to a multi function counter block in the hardware logic outline window ("Latch 0",
"Latch 1") as latch signals in the multi function counter block detail window.
Output
The following table shows the output of the latch input terminal.

*1 The latch input terminals and the latch event detection blocks are automatically linked in the following combinations, and the links
cannot be deleted.
 "Latch 0" terminal (latch input terminal) and "Input A" terminal (latch event detection block)
 "Latch 1" terminal (latch input terminal) and "Input B" terminal (latch event detection block)
