Default Mode

The High-Speed I/O circuit operates in one of 6 basic modes as listed in the table
below. The number in the left column is the mode number (later, we'll use these
numbers to configure the PLC). Choose one of the following modes according to the
primary function you want from the dedicated High-Speed I/O circuit. You can simply
use all eight inputs and six outputs as regular I/O points with Mode 60.

Input
In choosing one of the six high-speed I/O modes, the I/O points listed in the table
below operate only as the function listed. If an input point is not specifically used to
support a particular mode, it usually operates as a filtered input by default. Similarly,
output points operate normally unless Pulse Output mode is selected.

Mode 60 (Filtered Inputs) is the default mode. The DL05 is initialized to this mode at
the factory, and any time you reset V-memory scratchpad. In the default condition,
X0–X2 are filtered inputs (10 mS delay) and Y0–Y1 are standard outputs.
