DeviceNet Communications Specifications
Note
(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.
