The register structure of this module are described here.
It is possible to send or receive the data with EH-150 system using this module via Ethernet communication line.
This sending and receiving can be handled by Automatically Sending and Receiving function and user ladder
diagram. Simple communication can be done by only Automatically Sending and Receiving function without user
ladder diagram. By making user ladder diagram, it is possible to realized more complicated communication with
several equipment having Ethernet communication capability.
At this chapter the description of this register structure is very useful to make user ladder diagram to handle the
complicated communication.
8.1 Status Register
The information (communication parameter) related with communication of this module is shown by the status
area. Figure 8.1 shows the map of the status area. The status area is structured with 12 kinds of resisters. Each
register size is 1 word (16bits).
To get the data of this status area, FUN201 command is prepared for user ladder diagram programming.
