DeviceNet Connections Appendix B
Note 1. Output data using poll connections and output data using COS or cyclic connections are transmitted
using the same frame. Therefore set the same output size (bytes) when combining poll and COS or
poll and cyclic.
2. The COS/cyclic heartbeat timer is the smallest transmission interval for COS or cyclic connections.
It can be set for each corresponding slave.
Refer to DeviceNet Configurator Operation Manual (W382) for details on Configurator operation.
Connection Path
Connection path are parameters that specify the type of I/O data in the slaves. Depending on the type of slave,
the internal I/O data type may be able to be selected. If it can, the connection path and I/O data type in the
slave specified for remote I/O communications.
The connection path settings will differ depending on the allocation method, as outlined below.
Fixed Allocation or User-set Allocations Using DM
Connection path settings cannot be made.
User-set Allocations Using Configurator
The Configurator can be used to set the type of I/O data in the slave, using the connection path. The user can
use this method to set the I/O data type in the master and the remote I/O communications slave.
The connection path is saved by the Configurator to the CS/CJ-series DeviceNet Unit scan list and when the
remote I/O communications are started, the connection path is set to the slave via the DeviceNet network.
