Omron CJ1W-DRM21 Unit Series, DeviceNet Instructions, Master Unit To send, Any Fins Command

Overview Section 6-1

Note 1. The DeviceNet Unit must be registered in the local network routing table of the CS/CJ-series PC when two or more Communications Units (including the DeviceNet Unit) are mounted to a CS/CJ-series PC. The commands will not be sent if the Unit is not registered in the routing tables.

2.For DeviceNet networks connected to a CS/CJ-series DeviceNet Unit, message communications can be conducted between networks, including other DeviceNet networks as well as Controller Link, SYSMAC LINK, and Ethernet networks. Up to three levels of networks can be crossed. Routing tables (containing local network tables and relay network tables) must be registered in the CPU Units of each PC on the network.

Up to 3 network levels, including DeviceNet, can be crossed.

Note FINS commands sent and received by the CS/CJ-series DeviceNet Unit include commands addressed to the CS/CJ-series CPU Unit and commands addressed to the CS/CJ-series DeviceNet Unit.

FINS message communications is possible between two PCs with CS1W-

DRM21 or CJ1W-DRM21 DeviceNet Units.

FINS messages cannot be sent or received for PCs with C200H-series DeviceNet Master Units (C200HW-DRM21-V1) or CVM1/CV-series DeviceNet Master Units (CVM1-DRM21-V1). Explicit messages, however, can be received from these PCs.

The following table outlines which CPU Unit support for FINS message com- munications.
