DirectNET
The SJ-Ether programmer communication port (Port1) and the general-purpose communication port (Port2) can be connected
to the communication master or the master/slave PLC to perform data communication. This communication is called
DirectNET, and all protocols (communication procedures) are common to all Koyo’s PLC.
(1)
DirectNET function
The DirectNET function of the SJ-Ether general-purpose communication port enables reading and writing of the following
data.
・
Reading timer elapsed value and counter count value
・
Read/Write Data Register
・
Read/write function memory (bits) such as I/O, internal relay, stage, etc.
