CJ1W-DRM21
A DeviceNet Unit for the NJ/CJ Series
• Allows control of up to 32,000 points (2,000 words) per master, and ensures a high degree of
simultaneity between data.
• Can be used as both a master and a slave at the same time.
• Equipped with settings and monitor functions aimed at improving both design and startup efficiency.
Achieve maximum performance by using in combination with a Configurator.
• Files of master and slave settings can be uploaded and downloaded using memory cards, allowing
effective debugging and easier setup.
Ordering Information
Master/Slave Specifications
*1. Refer to the DeviceNet Operation Manual (W267) for the communications power supply specifications.
*2. The Device Unit uses a node, and so connection is possible to 63 slaves only.
*3. When the DeviceNet is used as a slave, “input” and “output” respectively refer to input from the slave to the master and output from the master to the slave.
*4. The maximum message length includes the command code when using the CMND instruction. (SendCmd instruction with NJ-series controller)
Note: When using with the Machine Automation Controller NJ Series, note the following points:
• Simple backup function cannot be used.
• DeviceNet configurator cannot be used. Use CX-Integrator.
