Sending Integer Values from Siemens PLC to Fanuc Robot - Is It Possible?

Question:

Hello everyone! I have been working with a Siemens 1500 PLC recently and I was wondering if it's possible to send integer values from the PLC to a robot. Is anyone else experienced with this? Let me know!

Utilizing group (GI[x]) definitions in the Fanuc Robot allows for better organization of discrete bits, enabling them to be treated as integers. It is recommended to transfer them into R[x] registers for optimal performance. This practice ensures smoother operations and enhances efficiency in programming and controlling the robot.

In the Fanuc Robot, grouping (GI[x]) definitions are crucial for bundling discrete bits together for easier use as integers. It is recommended to copy these grouped bits into R[x] registers. Do you require the Profinet add-on for the Fanuc system?

When working with Fanuc, it's crucial to have the Profinet add in installed. Otherwise, you may be limited to discrete operations. This integration is key for seamless communication and data exchange.

JRW mentioned the requirement of a Profinet add-on on the Fanuc side. The question seemed focused on data handling rather than networking, but the importance of the add-on cannot be ignored.

As the saying goes, making assumptions can lead to misunderstandings

Absolutely, it's very much possible to send integer values from a Siemens 1500 PLC to a robot. You'll want to look into leveraging the S7 communication protocol. Also, make sure to set up your DBs correctly on the PLC side. I did something similar where I sent conveyor position information to a pick-and-place robot. Let me know if you need a hand with anything specific!

Absolutely, it's actually a pretty straightforward process. You could use Profinet or OPC UA for this kind of communication. The PLC would write the integer values to certain addresses, and the robot can pick the value from that address. The specifics might vary depending on the type of robot you're working with, but broadly speaking, this method should work. Don't forget to ensure both devices are on the same network for communication to flow smoothly.
