Testing Communications - Omron FH series User Manual

Testing Communications

You can check whether the EtherNet/IP communications settings are correct.
If communications cannot be performed even after set up the communications, use the following procedure to
check the settings and the communications status.
Before Performing a Communications Test
This example assumes that [Serial (Ethernet)] − [Normal (UDP)] is selected as the Communications Module.
Stop the program on the PLC when you check the communications settings.
Checking the Communications Settings
Use the following procedure to check if the communications settings are correct.

Communicating with EtherNet/IP
1. On the Main Window, select [Tool] − [System Settings].
In the tree view on the left, select [System Settings] −
[Communication] − [Ethernet Normal (xyz)]. ("xyz"
depends on the Communications Module.)
2. Set the IP address of the Sensor Controller.
The default settings are as follows:
Address setting: 10.5.5.100
Address setting 2: 10.5.6.100
3. On the Main Window, select [Tool] − [System Settings].
Select [System Settings] − [Communication] −
[EtherNet/IP] from the tree view on the left.
4. Click the [Settings] tab.
5. Set the output control.
Set whether to provide an interlock with the PLC when
performing data output.
* Output Period
Set the cycle by which measurement results are output.
Set the value so that the interval is longer than the
output time and shorter than measurement interval.
Output time
Set the interval during which the GATE signal (the signal
that tells the PLC when to read the measurement
results) is ON.
This interval must be longer than the cycle time of the
PLC and the EtherNet/IP packet interval (RPI). Set
these values so that they satisfy the following relation-
ships:
RPI < Output time
GATE ON time = Output time
GATE OFF time = Output period − Output time
(The output period and output time are only valid when
output control is set to [None].)
6. This completes the Controller settings.
The PLC settings are set next.
