Network Instructions
Section 3-25
• Sending to a PLC operating as a Host Link Slave
When a CMND(490), SEND(090), or RECV(098) instruction is executed to
a serial port that supports the serial gateway function, the serial gateway
function can send any FINS command or send/receive data.
Communications from a Host Computer (Host Link)
It is possible to send FINS commands from a host computer to the PLC to
which it is connected as well as other devices in the network (CPU Units, Spe-
cial I/O Units, computers, etc.). In this case, the necessary Host Link header
and terminator must be attached to the FINS command when it is sent.
