Characteristics of the DL-PD1
The DL-PD1 is an interface unit, which enables sensor amplifiers or input units to
connect to the PROFIBUS DP. The characteristics of the DL-PD1 are shown below.
 Slave unit of the PROFIBUS DP-V1
 The following features are achieved by connecting the sensor amplifiers, which
are suitable for each application, in the form of a module.
•
Reading out the output of the sensor amplifier.
• Reading out the comparator value (the measurement value) of the sensor
amplifier.
• Changing the configuration of the sensor amplifier.
 Two selectable operational modes
•
Monitor Mode: Input size - MAX 107 bytes, Output size - MAX 16 bytes
• I/O Mode: Input size - 10 bytes, Output size - 10 bytes
 Corresponding to the communication speed of 9.6 Kbits/s to 12 Mbits/s
 System configuration example
Additional sensor amplifiers corresponding to the D-bus can be connected to the DL-
PD1. ("D-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.)
Any sensor amplifiers corresponding to the D-bus allow different models and up to 15
units of sensor amplifiers to be connected simultaneously.
Connectable quantity depends on the sensor amplifier which is connected to.
