9.2 Multi Function Counter Block
Input
The following table shows the inputs of the multi function counter block.
*1 Only the "Event" terminals of multi function counter blocks can be linked.

Variable name Data type Linkable block Valid range Description
Input 0 Bit • External input
•OUT
• Y device
0, 1 The input terminals are for external input signals. The
terminal executes OR processing for all signals input to
the "Input" terminal.

Latch 0 Bit • External input
•OUT
• Y device
0, 1 • The input terminals are for latch. The terminal
executes OR processing for all signals input to the
"Latch" terminal.
• The "Latch 1" terminal can be used in 16-bit multi
function counter blocks only.
Latch 1
Event 0 Bit Multi function counter
*1
0, 1 • The input terminals are for events. The terminal
executes OR processing for all signals input to the
"Event" terminal.
• The "Event 2" and "Event 3" terminals can be used in
16-bit multi function counter blocks only.
Event 1
Event 2
Event 3
Absolute Encoder Word Parallel encoder 0 to 4095 Inputs the encoder value of the absolute encoder
(parallel encoder block). The input encoder value is
used as a preset value of the counter timer block in the
multi function counter block detail window.
SSI encoder 0 to 4294967295 Inputs the encoder value of the absolute encoder (SSI
encoder block). The input encoder value is stored as a
count value of the counter timer block in the multi
function counter block detail window.
