(3) Loader communication (client operation)
The "loader communication (client operation)" mode supports TCP/IP only (UDP/IP is not supported.)
This mode is used to read/write the data memory in target device (SPH or SPF).
"R_READ" (for reading data) and "R_WRITE" (for writing data) FBs are used for communication. Start these FBs to send a
loader command from the self station to the target device.
No communication program is required on the target device since it operates as a server.
