SRQ for LAN/RS-232C communication
These commands are for LAN communication.
If you use them on RS-232C communication, replace “LN_” to “RS_” on the
commands.
The SRQ output flag is independent for LAN_H, LAN_L, and RS-232C.
In PM16C-16HW2, there are 8 ports for LAN_H and LAN_L respectively, but the
port where SRQ is output is the port that sent "LN_SRQx1" (x: 0 to F) at the end.
Example)
Send "LN_SRQ11" to LAN_H, port 1
Send "LN_SRQ11" to LAN_L, port 1
Send "LN_SRQ21" to LAN_H, port 2
If you do these in sequence, the SRQ will be
"STOP1" and "STOP2" are output to LAN_H and port 2, and "STOP1" is output to
LAN_L and port 1.
