Communicating with the GT2 Series
Types and Number of Connectable Sensor Amplifiers
* Up to 11 sensor heads can be connected by adding a head connection board to the
main unit.
The DL-PN1 can connect to multiple sensor amplifiers (a single main unit and multiple
expansion units) which support D-bus. "D-bus" is the name of KEYENCE's wiring-saving
system for sensor amplifiers.
Different types of sensor amplifiers with D-bus support can be connected to a single DL-PN1 unit.
How many and what types of sensor amplifiers can be connected depends on the
sensor amplifiers or units to be connected. Please inquire for details.
Assigning ID Numbers and Slot Numbers
Several sensor amplifiers can be connected to the DL-PN1. ID numbers and slot
numbers for data identification are assigned to each sensor amplifier.
The method for assigning ID numbers and slot numbers is as follows:
• The numbers are assigned in order, starting from the sensor amplifier that is the main
unit. (Optional numbers cannot be assigned.)
• 00 is assigned as the ID number and slot number of the DL-PN1.
Point
• You cannot change the ID numbers and slot numbers assigned to
the sensor amplifiers.
• In this manual, ID number 00 to ID number 15 are denoted as ID00 to
ID15, and slot number 00 to slot number 15 are denoted as Slot0 to
Slot15 respectively.
