DL-DN1 Overview
The DL-DN1 operates as a slave unit of DeviceNet communication. Using DeviceNet
communications, the sensor amplifiers and other units connected to the DL-DN1 can
transmit their ON/OFF control signals and current values as communication data to a
PLC or other equipment.
The DL-DN1 supports DeviceNet I/O communication (polling) and explicit messaging.
I/O polling enables data communication without the need of a ladder program. Explicit
messaging allows for reading/writing sensor amplifier parameters and issuing motion
commands to the sensor amplifiers.
System configuration example
Number of Connectable Sensor Amplifiers
* Up to 11 sensor heads can be connected by adding a head connection board to
the main unit.
