11 Appendix DVP-FEN01 (DVP-EH3 Series Ethernet Communication Card) Searching for an Ethernet PLC This section introduces how to search for and set an Ethernet PLC by DCISoft. Before you start a setup page, you have to select Ethernet in the Communication Setting window.
Next, you can search by a broadcast, or an IP DVP-PLC Application Manual 11-17 DVPEN01-SL Ethernet communication module CR number Attribute Register name Description HW LW #116 R/W MODBUS TCP status Displaying current status of MODBUS TCP mode #118 #117 R/W MODBUS TCP destination IP Setting up destination IP address for MODBUS TCP transaction #119 R/W MODBUS TCP data length Setting up the data length for MODBUS TCP transaction #219 ~ #120 R/W MODBUS TCP data buffer Data buffer of MODBUS TCP for storing sending/receiving data #248 ~ #220 - Reserved #251 R Error code Displaying the errors.
