Communicating with the SK-1000 Series
Types and Number of Connectable Sensor Amplifiers
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 8 are denoted as ID00 to
ID8, and slot number 00 to slot number 8 are denoted as Slot0 to
Slot8 respectively.
