6-3-(2)
If the communications mode is set to Host link, the Controller can communi-
cate with a host device such as a Programmable Controller (PLC) through its
serial interface using the host link protocol.
Only a 1:1 connection can be made with host link; the Controller's host link
does not support 1:N connections.
Set the output data using the Host Link data output processing item.
• Setting Mode
Command inputs are not received.
• Monitor Mode
Command inputs are received, but the measurement results are not out-
put to external devices.
When a command is input to read a set value, the appropriate value will
be output.
• Run Mode
Command inputs are received and measurement results are output.
After measurements have been made in Run Mode, the data up through the
last measurement will be output even if the mode is changed to another mode.
The data output will not be interrupted midway.
