About this Manual:

This manual describes the installation and operation of CS1W-DRM21 DeviceNet Unit for SYSMAC CJ-series PLCs and the CJ1W-DRM21 DeviceNet Unit for SYSMAC CJ-series PLCs, and includes the sections described below.

Please read this manual and all manuals for related products carefully and be sure you understand the information provided before attempting to install and operate the DeviceNet Unit. Be sure to read the precautions provided in the following section.

Section 1 provides an overview of the DeviceNet network, including features, specifications, and sys- tem.

Section 2 describes the nomenclature and installation of the DeviceNet Unit.

Section 3 describes the words allocated to the DeviceNet Unit in the CIO Area and DM Area. These words both enable controlling the DeviceNet Unit and accessing Unit and network status.

Section 4 describes the remote I/O communications performed as a master by the DeviceNet Unit.

Section 5 describes the remote I/O communications performed as a slave by the DeviceNet Unit.

Section 6 describes message communications using FINS commands sent from the ladder program in the CPU Unit of the PC.

Section 7 describes connecting to CX-Programmer via the DeviceNet and the Memory Card backup function.

Section 8 describes the time required for remote I/O communications and message communications.

Section 9 describes error processing, periodic maintenance, and troubleshooting procedures needed to keep the DeviceNet network operating properly. We recommend reading through the error process- ing procedures before operation so that operating errors can be identified and corrected more quickly.

The Appendices provide information on allocation differences with C200H-series DeviceNet Units, DeviceNet connections, remote programming and monitoring, Memory Card backups, FINS com- mands and responses, sending DeviceNet explicit message to Non-OMRON nodes, and multi-vendor applications.

The following manuals provide information on the DeviceNet and OMRON DeviceNet products.
