11 Appendix 11.7 Appendix G: Using Ethernet Communication Specifications for an Ethernet interface: The specifications for a DVP series Ethernet port and the functions of a DVP series Ethernet port are listed below. Ethernet functions: Station Addresses of Ethernet Modules and Control Registers Station Addresses of Ethernet Modules Example 1. Suppose a DVP-SV series PLC is connected to three left-side communication modules. DVP-SE Series PLC (Ethernet PLC) In order to control and monitor Ethernet communication, users can read the data in the control registers listed below by means of the instruction FROM, and write data into the control registers listed below by means of the instruction TO.
(Please refer to the explanation of API 78 and that of API 79 in chapter 3 for more information about FROM/TO.) [Note] Please refer to DVPEN01-SL Manual for more information about control registers.
