Conforms to DeviceNet
• Master-slave connections (polling, bit-strobe, COS, or cyclic)
• Conform to DeviceNet specifications.
• Can allocate any I/O data from the Configurator.
• Can allocate any data, such parameters specific to the DeviceNet and the Digital
Controller variable area.
• Up to 2 blocks for the IN Area, up to a total of 100 words (See note 1.)
• One block for the OUT Area, up to 100 words (The first word is always allocated to
Output Enable Bits.) (See note 2.)
• Explicit message communications
• CompoWay/F communications commands can be sent (commands are sent in
explicit message format).
Combination of multidrop and T-branch connections (for trunk and drop lines)

CRC error detection
Power supplied from DeviceNet communications connector
(1) The IN Area can be divided into two blocks only when a CS/CJ-series De-
viceNet Unit is used as the master. (The connection type can also be se-
lected.) If a CVM1, CV, or C200HX/HG/HE DeviceNet Master Unit is used
as the master, the IN Area must be in 1 block with a maximum 100 words
(200 bytes). (Polling connection only.)
(2) If a CVM1, CV, or C200HX/HG/HE DeviceNet Master Unit used, only up
to 32 words can be allocated per node.
