Choosing the HSIO Operating Mode
Understanding the Six Modes
The High-Speed I/O circuit operates in one of the 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.
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.
Default Mode
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
