Choosing the HSIO Operating Mode
Understanding the Six Modes
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 twenty inputs and sixteen
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.
