Internal Blocks Of Multi Function Counter Blocks - Mitsubishi Electric MELSEC iQ-R User Manual

Internal blocks of multi function counter blocks

There are 14 types of internal blocks in a multi function counter block. Control operations can be freely customized by linking
the internal blocks. When a multi function counter block is arranged in the hardware logic outline window, all internal blocks
are arranged in the multi function counter block detail window.
• 32-bit multi function counter block detail window
• 16-bit multi function counter block detail window
Internal block list
The multi function counter internal blocks are as follows.

Fifth section Set/reset block
Sixth section Output terminal
Event output terminal
Pattern generator output terminal
Cam switch output terminal
*1 This block is arranged across the fourth and fifth sections.
*2 This block is arranged only in 16-bit unsigned multi function counter blocks.
