5. In the Tx field, enter 4 for the size of the I/O output.
6. In the Send Rate field, enter the desired time for the interval
between messages.
7. Click OK.
Important: After you have configured the scanner and adapter for
Cyclic, you can verify the desired send rate is used by viewing the
COS/CYC Interval (28) parameter in the adapter.
Polled and COS Allocation
You can enable both polling and COS allocations. This lets the
scanner poll the adapter at a fixed interval and the adapter report its
status changes to the scanner after they occur.
Enabling Polling and COS in the Adapter
Refer to both the “Polled Allocation” and the “COS (Change of State)
Allocation” sections in this chapter for information.
Enabling Polling and COS in the Scanner
Use RSNetWorx to enable polling in the scanner. Refer to Chapter 4,
Configuring a Scanner to Communicate with the Adapter, for more
information on configuring the scanner.
Polling and COS must be enabled in the Edit Device I/O Parameters
dialog box.
