1 Introduction 
Thank you for choosing DVPEN01-SL module. To correctly install and operate DVPEN01-SL, please read 
the manual carefully before using the module. 
DVPEN01-SL is an Ethernet communication module for remote setting and communication through 
WPLSoft. DVPEN01-SL is able to send E-mails, automatically correct the RTC in DVP28SV11R/T and 
exchange data. It supports Modbus TCP communication protocol and can conduct remote monitoring by using 
SCADA (Supervisor Control and Data Acquisition) software or HMI (Human Machine Interfaces). DVPEN01-SL 
can be the master of Modbus TCP, sending out Modbus TCP instructions and controlling the peripheral 
equipment. In addition, under MDI/MDI-X auto-detection, it does not need to use a crossing cable. See the 
contents below for more detailed instructions on DVPEN01-SL module.
