IN area
n: The first device number assigned to the DL-DN1
The device assignments are the same for all 5-output modes including extended
modes.
The following describes how the DeviceNet master unit communicates with the DL-
DN1 (slave unit) using I/O communication (polling).
"Reading an output from a sensor amplifier" (page 3-15)
"Entering an external input into a sensor amplifier" (page 3-16)
"Reading comparator values (P.V. values) from sensor amplifiers" (page 3-17)
"Changing the BANK number of sensor amplifiers" (page 3-18)

For the communication methods using explicit messaging, see "Explicit
Messaging" (page 3-20).
Reading an output from a sensor amplifier
Available outputs: HIGH, LOW, GO, and alarm output
Device assignments: "Output" (page 3-8)
This example reads the HIGH output from the sensor amplifier of ID01.
It assumes that the operating mode assigned to the device is 3-output mode.
(1)The output from the sensor amplifier is brought into the IN area by I/O
communication.
