To Read a Digital Input Port
The multifunction module (34907A) has two non-isolated 8-bit
input/output ports which you can use for reading digital patterns. You can read
the live status of the bits on the port or you can configure a scan to include a
digital read.

Select the Digital Input port.
Select the slot containing the multifunction module and continue turning the
knob until
DIN
is displayed (channel 01 or 02).

You can specify whether you want to use binary or decimal format. Once you
have selected the number base, it is used for all input or output operations on
the same port. To change the number base, press the
key and select
USE BINARY
or
USE DECIMAL
.
The bit pattern read from the port will be displayed until you press another key,
