Let’s play with Ethernet!
Industrial Ethernet has become the last 10 years as the replacement for the serial communication. Not only because the speed, but for the simple compatibility with our main tools, the computers…
Each automation brand have their own protocol based on Ethernet (Profinet, Ethernet/IP, Ethernet Powerlink, etc…).
In Delta, we have been playing with Modbus from the beginning, so in the moment that we decide to enter to ethernet, the natural choice was Modbus TCP/IP.
But what happen with all the devices already in the factories working with Modbus RS232 or RS485 ?
To solve this need, we develop IFD9506.
This device is used to convert from Ethernet Modbus TCP/IP to serial communication Modbus.
And the following weeks we’ll share with you all several typical applications and functionalities of this device.
To start, we are going to use the simple communication HMI-PLC-DTB and we’re going to add two IFD9506 to achieve to communicate both three devices trough Ethernet as the picture shows.
To achieved, use the attached application tutorial.

HMI to VFD Communication:
Greetings of the day!
I am using HMI B07S211 and VFD-L and I want to communicate my VFD with HMI on RS-485 communication, and we have different connectors available in market, how much pins should be in the connector to connect the VFD, 6 pins LAN/Ethernet connector or one with 4 pins? Kindly provide answer for my answer
