Overview Section 6-1
Sending FINS Message Communications
Receiving FINS Message Communications
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.
