PROFIBUS communication function of DL-PD1
This section describes the overview of the PROFIBUS DP communication functions the
DL-PD1 supports.
Overview
The DL-PD1 operates as a slave unit for PROFIBUS DP. The sensor amplifier output or
comparator value can be read via the cyclic communication, and the sensor amplifier's
external input ON/OFF can be controlled. Also, setting the DL-PD1 or sensor amplifier
connected to DL-PD1 and reading/writing the status of them are possible via the acyclic
communication of the DP-V1 service.
