ARC - Read Characters
Instruction Type: output
The ARC instruction is used to read characters from the buffer, and store
them in the String Data Table.
The parameters are:
• CH : serial port number ( 0:COM1, 1:COM2, 2:USB)
• CTRL : CR (Control) data table
• Length : data length to read
TIP
If 2 (USB) is set to CH, Error 3 is generated since the USB is not

Handshake control is only possible in ASCII/BIN communications.
Other protocols are controlled in PLC autonomously.
