=============================
Welcome to Part 2 of Rockwell ControlLogix PLC and Siemens VFD Communication.
As you have learned in part one (realpars.com/connect-vfd-to-p..., automation often requires communication between two heterogeneous systems from different manufacturers.
In this video series, overall, we are communicating from a Rockwell Automation ControlLogix 5000 PLC using ControlNet network media with CIP protocol to a Siemens Robicon VFD using Profibus protocol, through a gateway converting ControlNet CIP protocol to Siemens Profibus protocol.
As a prerequisite, please watch Part 1 of this video series, addressing how the communication between ControlLogix 5000 PLC and the HMS Anybus gateway is configured. (realpars.com/connect-vfd-to-plc/)
In part 2, this video, we are going to discuss how the HMS Anybus PROFIBUS Master gateway is configured to communicate with the Siemens Robicon VFD.
Finally, the third and last part will address the Siemens Robicon PROFIBUS slave configuration.
The ControlLogix PLC will be controlling a pump with a simple ON/OFF command and velocity by setting a speed setpoint to the VFD.
In response, the Siemens VFD will return the actual speed reference and VFD status information controlling the pump.
This exchange of control data and status information is all performed by the HMS gateway.
The HMS Gateway also performs an important responsibility as PROFIBUS Master controlling the Pump VFD.
First, let’s review what the PROFIBUS master is responsible for. The PROFIBUS master controls the entire communication dialog with the salves on the network.
The master writes and reads data from each slave one at a time. Each slave is required to respond to the request within a predetermined timeframe or the master will report a communication error.
Configuring the PROFIBUS Master in the gateway is accomplished by using HMS NetTool software.
The HMS PROFIBUS configuration is set to use 30 bytes of input for real I/O data and status data for ControlLogix PLC and 6 bytes of output to be controlled by the ControlLogix PLC respectively.
Using a null modem cable, we will connect to the COM port on a laptop and the COM port on the Gateway marked “PROFIBUS Config Connector”.
Next, in Part 3, we will discuss how to configure this input/output data in the Robicon VFD.

Thanks for doing the followup video in part and as a series with part 3 coming soon.
You are very welcome, Ardent! Happy to hear that you enjoyed it.
Waiting for the remaining parts of this series.
Please upload at the earliest
Thanks!
Thanks RealPar... You've done it again !!!!
Thanks for your support, Emmanuel! Always happy to read your positive comments!
Thank you for that great vedio, keep in progress
Thank you, Alaa!
Thank you very much, from Manaus-Am-Brazil.👍👏
You are very welcome, Wilson! Happy learning.
Thanks man great job 😎
Thank you!
very good job
thank you so much for this efforts
I'm really learned a lot from your videos
many thanks
Really happy to hear that! Thank you!
Useful information
Thank you!
Good job thanks
Thank you!
more training on this configuration please
Thanks for great information and videos. Where is the part 3 of this video ?
Hey Rizwan,
Here is the link to Part 3 czcams.com/video/bqIf18tChFI/video.html
Happy learning!
Please make a video on siemens envoirnment
Thanks a lot for your great effort to making these great videos.
One question: I can find 6 bytes(3 words) output data from PLC to VFD. But where are the 30 bytes of feedback data from VFD to PLC? I found only 18 bytes(9 words) of feedback data(main setpoint, BICO status word, speed, current, torque, power, etc.)?
Hello Shi Billy. Keep in mind there is an HMS protocol converter in between the PLC and VFD. We are sending two bits and one worked from the PLC to the HMS converter. And the HMS is sending (writing) ZSW1 16 bits and 9 words of data. HMS reads N_Set_A frequency and STW1 16-bit word used for discrete bits STW1.0 -STW.15
Sir please make a video Siemens VFD control program with Siemens PLC
Yes please do this
Yes yes yes. We need it. realpars awesome
Thanks for the topic suggestion, I will definitely go ahead and forward this to our creator team. Happy learning!
@@realpars Many thanks to your reply
👍👍
Great video! Do you think to make a video about I/O link?
Thanks for your compliment and topic suggestion! I will definitely go ahead and forward this to our creator team. Happy learning!
Great video for learning but i want to know in a 4 core profinet cable
Whats the function of each wire out of those 4
And difference between profinet and ethernet
Thank you
Yellow = transmit (+), White = receive (+), Orange = transmit (-), Blue = receive (-). PROFINET is for industrial applications where there is high RF/EMI noise. Industrial machinery running electrical motors is going to give off a lot of interference that standard "office" ethernet cables are unable to filter out. PROFINET and other industrial ethernet protocols (Ethernet/IP, for example) are all based on TCP/IP, use IP addresses, support UDP, etc. The differences in each are in the application of the upper levels of the OSI model for protocols (levels 5, 6, and 7).
@@scottsommer5450 thank you so much
Why we are using 2 for transmit 2 for receive
Why cant we use just only 1 for transmit 1 for receive
Like profibus
Why double in profinet?
Hii...i am having an issue voltage across 3 phase aren't same voltage across R - N and B - N phase are 243 but across Y - N it is 233 due to this MCB of VFD is tripping
Pls help....
Vfd doesn't trips eaven if a phase missing in supply. The only required for the vfd is that the 2 phases remaning or the three not symmetric have to carry the power required on the load.
Artan is correct in his answer to your question. An unbalanced 3-phase load is not going to trip a VFD due to the unbalance. Also, 10 VAC is not a very larger or significant difference. This could be caused by something as simple as increased resistance at one lug set due to corrosion or poor conduction.
I would do some basic troubleshooting: 1) with the VFD turned off, do you still see the unbalanced voltages? 2) with all devices on the branch circuit that feeds this VFD, do you still see the unbalanced voltages? It is important to know if the unbalance exists at the source of power (switchgear transformer), on a branch circuit, or at the VFD itself.
If the VFD branch circuit has other loads on it other than the VFD, then those other loads may be the cause of the unbalance. Are there upstream line reactors, filters, or fuses that could be partially failed that would cause a voltage drop on one branch?
