Control/Output through EtherNet/IP
FZ4 User's Manual
For data output (with handshaking)
For data output (without handshaking)
Important
●
Set the data output cycle and time so that the following conditions are satisfied.
●
Set the measurement tact interval so that the measurement tact interval is longer than the measurement
processing time.
●
Set an output cycle that is longer than the output time, but shorter than the measurement interval.
●
Set the output time that is longer than the PLC cycle time and the EtherNet/IP communication cycle.
●
Since a reasonable amount of measurement tact time is required to have stable communications in an
operation under high load, verify the operation under the conditions that are to be actually applied.
●
Since a large portion of the CPU load is allocated to measurement processing while the multiple input function
is being used, a reduction in the performance (such as delayed response and packet loss), or a communication
error may occur.
Do not use EtherNet/IP communication when the multiple input function is being used.
●
If the measurement interval is short, a communication error may occur depending on the measurement
processing time and the PLC settings.Set a PLC timeout time longer than the measurement processing time, or
increase the measurement intervals.
Communicating with the controller with Ethernet/IP message communications
The message communication function is used when communicating with a PLC that does not support
tag data link communication or when using functions, such as character string output, that are not
supported in tag data link communication.
Message communication can be performed either by exchanging the same data as for tag data link
communication using AssemblyObjects or by sending and receiving commands equivalent to
non-procedure commands using FZ4-specific VisionSystemObjects.
This document explains centered on AssemblyObjects and FZ4-specific VisionSystemObjects. For
information on the procedure for issuing messages, refer to the User's Manual for the PLC you are
using.
Object composition
The controller's EtherNet/IP function has the following objects. These objects can be accessed using
message communication.
