PLC CJ2M-MD211/MD212 dimensional outline drawings, Units: mm
Features
- PLC Improved basic computation performance such as a reduced LD command execution time of 40 ns and a SIN computation time of 0.86 μs. Faster function block calls as well.
- Optional pulse I/O modules (maximum of 2) can be mounted to enable positioning functions for up to four axes. Supports 4-point high-speed counters and 8-point interrupt inputs.
(CJ2M CPU Unit Ver. 2.0 or later) - Provides a dedicated storage area for function blocks, reducing the user program area usage amount, even with structured or parts-oriented programming using function blocks.

Function Specifications of OMRON PLC
| Function PLC | Function Description | ||
|---|---|---|---|
| Pulse I/O Function | Input Function | General Purpose Input | Input signals are read during I/O refreshing and stored in I/O memory |
| Interrupt Input | An interrupt task can be started when an input signal turns ON or turns OFF | ||
| Quick Response Input | Input signals that are shorter than the cycle time are read and stored in I/O memory | ||
| High Speed Counter Input | High-speed pulse signals are counted. Interrupt tasks can also be started | ||
| Output Function | General-Purpose Output | The status of I/O memory is output during I/O refreshing | |
| Pulse Output | A pulse signal is output with the specified frequency and number of pulses at a fixed duty ratio (50%) | ||
| PWM Output | A pulse signal is output at the specified duty ratio | ||
| Origin Search Function | The origin point of the machine is determined according to the specified origin search parameters while actually outputting pulses and using the origin and origin proximity input signals as conditions (pulse inputs and outputs are alsoused for this function) | ||
| Interrupt Function | Input Interrupt Function | A task is started for an interrupt input from a pulse I/O module or for a high-speed counter input | |
| Input Interrupt | Interrupt tasks are executed when the interrupt input turns from OFF→ON or ON→OFF Direct mode: An interrupt task is executed each time an input signal changes Counter mode: Changes in the input signal are counted up or down and the interrupt task is executed when the counter counts up (the maximum response frequency is 3 kHz) | ||
| High Speed Counter Interrupt | An interrupt task is executed when preset comparison conditions for a high-speed counter are met Target-value comparison: The interrupt task is executed when the count matches a specified value. Range comparison: The interrupt task is executed when the count enters or leaves a specified range of values | ||
