8-10 Using the SCANport Capabilities
SLC to SCANport Module
The following figure shows how the I/O image table for the SLC
programmable controller relates to the 1336 IMPACT drive. In this
example, the drive is connected to channel 1 of the SLC module in
enhanced mode. If this were an example of basic mode, only the
O:1.2, O:1.3, I:1.2, and I:1.3 entries would be used.
