You can use the Ewon to access remotely an Omron® PLC.
The following simplified configuration process is based on the CX-Programmer® software, provided by Omron.
You can find a more detailed version of how to remote access an Omron® PLC in the Documentation section here under or in the Downloads and Documentation.
Step #1
Before opening the CX-Programmer software, make sure the VPN tunnel between your computer and the eWON is established (i.e.: via eCatcher)
Now that the software is open,open your PLC project, right-click on the main entry and select Change.
Step #2
The Network Type can be either Ethernet (FINS/TCP) or Ethernet.
Click on Settings to configure the parameters of the network type.
Step #3
As the the Network tab is selected, keep the default value for the Network and Node fields of the FINS Destination address section.
You should however increase the Response timeout.
Step #4
Switch to the Driver tab.
Insert a proper IP address for the PLC. This one needs to be in the same IP range than the eWON.
Set the TCP server port to 9600 and check the Auto-negotiation box.
Step #5
You are done with the configuration of the software.
Perform a test connection to make sure everything is working as it should.
