Note C200H-series DeviceNet Master Units (C200H-DRM21-V1) and CVM1/CV- series DeviceNet Master Units (CVM1-DRM21-V1) both support FINS mes- sage communications but it is executed by a special OMRON method. With this CS/CJ-series DeviceNet Unit (CS1W-DRM21 or CJ1W-DRM21), the standard message protocol for DeviceNet (i.e., explicit messages) has been used for FINS communications. For this reason, FINS communications is not possible between CS/CJ-series DeviceNet Units (CS1W-DRM21 or CJ1W- DRM21) and C200H-series DeviceNet Master Units (C200H-DRM21-V1) or CVM1/CV-series DeviceNet Master Units (CVM1-DRM21-V1).

6-1-3 Explicit Message Communications

Service requests can be sent to C200H I/O Link Units and other OMRON slaves, PCs with CS/CJ-series DeviceNet Units, and DeviceNet masters and slaves made by other manufacturers using explicit messages defined for DeviceNet.

Service requests to read/write CPU Unit status I/O memory can also be received from PCs with C200H-series DeviceNet Master Units (C200HW- DRM21-V1), PCs with CVM1/CV-series DeviceNet Master Units (CVM1- DRM21-V1), PCs with CS/CJ-series DeviceNet Units, and DeviceNet masters made by other manufacturers using explicit messages.
