Module Operation

Channel Scanning Sequence for a DL230 CPU (Multiplexing)

Before beginning to write the control program, it is important to take a few minutes to

understand how the module processes and represents the analog signals.
The F2-08AD-1 can supply different amounts of data per scan, depending on the type of

CPU being used. The DL230 can obtain one channel of data per CPU scan. Since there are

eight channels, it can take up to eight scans to get data for all channels. Once all channels

have been scanned the process starts over with channel 1. Unused channels are not processed,

so if only two channels are selected, then each channel will be updated every other scan. The

multiplexing method can also be used for the DL240/250-1 and DL260 CPUs.

Channel 1
