DeviceNet Connections

Appendix B

The following diagram shows the transmission timing. After the COS send instruction has been sent to the DeviceNet (at the I/O refresh timing for the CPU Unit), the COS transmission is executed to each slave immedi- ately after the refresh (remote I/O communications), which each slave is performed during the communications cycle. Therefore, when there are a lot of destination slaves, the COS send timing may be delayed in order of the node addresses.

Multiple COS send switches (node address #1, #2, #3) turned OFF to ON
