Communicating through Serial Communication (PLC Link)
This section explains how to set the required communication specifications and the input format when
using PLC Link to communicate with external devices.
Communication Processing Flow (PLC Link)
Communication between the PLC and FZ3 is performed using the 3 link areas indicated below: the
command area, response area, and data area.
The command area is used when control commands are sent from the PLC to the FZ3.
The FZ3 can be controlled by writing commands to the command area.
In the response area, the execution results of control commands described in the command area are
written.
The output data accompanying measurement is written to the data output area.
When using PLC Link, it is necessary to specify PLC Link with the communication module.
