SYSMAC CJ-series CJ2M CPU Units, Pulse I/O Modules
CJ2M-CPU3@/-CPU1@/-MD21@
CSM_CJ2M-CPU3__-CPU1__-MD21__DS_E_10_2
Since 2001, CJ1M-series PLCs are in
control of a wide variety of
applications worldwide.
The accumulated experience and
advancements in technology now
result in CJ2M; fully compatible, yet
fully new.
CJ2M-MD21@
CJ2M-CPU3@
CJ2M-CPU1@
• Increased performance, and increased memory capacity
• Up to 40 I/O unit on any CPU
• Pulse I/O Modules add position control functions to any CPU
• USB for plug-and-play access to the PLC
• All models available with or without Ethernet port
• Choice of serial port plug-in modules
Features
• Five variations in program capacity from 5K steps to 60K steps; scale the CPU to your application needs.
• Faster processors; LD instruction execution time is reduced to 40 ns, floating point trigonometrics in less than 1 μs.
• Optional Pulse I/O Modules can be mounted to enable positioning functions for up to four axes. The module provides high-speed counters,
interrupt inputs and pulse train/PWM outputs. (CJ2M CPU Units with Unit Version 2.0 or Later)
• Faster Function Block calls and execution, faster interrupt handling, less overhead time.
• Added execution memory for Function Blocks allows structured, object-oriented programming even in entry-level CPUs.
• General-purpose Ethernet port supports EtherNet/IP tag-based data links, connection to Support Software, communications between PLCs,
FTP data transfers, and more (CJ2M-CPU3@).
• Standard USB port on all models allows Support Software to connect directly through standard USB cable.
• A Serial Option Module can be mounted to add RS-232C or RS-422A/485 communications ports (CJ2M-CPU3@).
• Compatible with all existing CJ1 power supply-, I/O-, control- and communication units.

*10.When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a timeout will temporarily
occur at the other node that was communicating with that port, and it will then recover automatically.
*11.The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using an Ethernet switch that supports IGMP
snooping.

Description
Input signals are read during I/O refreshing and stored in I/O memory.
An interrupt task can be started when an input signal turns ON or turns OFF.
Input signals that are shorter than the cycle time are read and stored in I/O memory.
High-speed pulse signals are counted. Interrupt tasks can also be started.
The status of I/O memory is output during I/O refreshing.
A pulse signal is output with the specified frequency and number of pulses at a fixed duty ratio (50%).
A pulse signal is output at the specified duty ratio.
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 also used for this function.)
A task is started for an interrupt input from a Pulse I/O Module or for a high-speed counter input.
Interrupt tasks are executed when the interrupt input turns ON or turns 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 out. (The maximum response frequency is 3 kHz.)
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.

Counter reset method
• Phase-Z + Software reset
The counter is reset when the phase-Z input goes ON while the Reset Bit (A531.00 to A531.03) is ON.
• Software reset
The counter is reset when the Reset Bit (A531.00 to A531.03) is turned ON.
Operation can be set to stop or continue the comparison operation when the high-speed counter is reset.

The acceleration and deceleration rates can be set independently only with the PLS2 (887) instruction.
Changing SVs during instruction execution
The target frequency, acceleration/deceleration rate, and target position can be changed.

Number of output pulses
Relative coordinates: 0000 0000 to 7FFF FFFF hex (Accelerating or decelerating in either direction: 2,147,483,647)
Absolute coordinates: 8000 0000 to 7FFF FFFF hex (−2,147,483,648 to 2,147,483,647)
Relative/absolute coordinate specifications
for pulse output PVs
Absolute coordinates are specified automatically when the origin location has been defined by changing the pulse
output PV with the INI (880) instruction or performing an origin search with the ORG(889) instruction. Relative
coordinates must be used when the origin is undefined.
Relative pulse/absolute pulse specifications
The pulse type can be specified with an operand in the PULS (886) or PLS2 (887) instruction.
Absolute pulses can be used when absolute coordinates are specified for the pulse output PV, i.e. the origin location
has been defined. Absolute pulse cannot be used when relative coordinates are specified, i.e., when the origin location
is undefined. An instruction error will occur.
Pulse output PV's storage location
The following Auxiliary Area words contain the pulse output PVs
Pulse output 0: A277 (leftmost 4 digits) and A276 (rightmost 4 digits)
Pulse output 1: A279 (leftmost 4 digits) and A278 (rightmost 4 digits)
