Thanks for the video. But I have a question. When I check the price of weidmüller IO modules, they seem pretty much. (Same with s7 1200 plc & modules or higher) Of course, I don't know the details in this situation but if I design something like that, I prefer a plc that communicates over profinet with controller plc instead of I/O module . All specifications I/O modules have existed in plcs too. Why do we prefer weidmüller or other I/O modules instead of a plc?
There are many reasons to choose an I/O subsystem such as Weidemuller. One is the cost of hardware and installation. The other is the physical space requirements for installation. For compact I/O such as this, it is easy to install a small rack with 10-12 I/O in a very small space, where S7-1200 I/O would require a much larger footprint. In many machine control applications, I may need 1 or 2 I/O of different types, and the smaller footprint of the I/O cards makes the overall installation more compact.
Web servers usually available in CPUs. IOs can be forced from there also in my Brands. What does it mean by forcing IOs of a remote station? Can the IOs be forced directly without having access to CPU and it’s program?
Every PLC is different, and some do no allow forcing at all. But for those which do allow it, you are typically able to force outputs from the programming station for any output regardless of where the DO card is located (local rack or remote rack). When you force and output, you are overriding the output image table in the CPU, and the CPU communicates that change to the I/O rack. The presence of a force is indicated at the CPU, not at the remote I/O rack. The remote I/O rack simply places the output states to what is sent to it by the CPU.
Will Weidmuller still suport them 40 years later, like the other big names do? Didnt even know they did automation stuff, only know them from their pliers and acient looking terminal blocks
A web server is firmware that is embedded into a device, such as a PLC, that allows the device's data to be accessed using a web browser. With an embedded web server, it can be possible to configure and monitor the device using an ethernet connection to the device without application software other than a web browser. When comparing communication protocols, speed and bandwidth are important. Profibus can be configured to operate at many different speeds; Modbus comes in many "flavors", including RTU and TCP. Modbus TCP runs at the same speed as ethernet (10Mbps or 100Mbps). ProfibusDP can operate at 1.2Mbps, so theoretically, Modbus TCP is faster. By the same token, even the slowest Profibus DP baud rate is faster than the fastest Modbus RTU rate. But do differences in speed really matter for communication with an I/O rack or VFD that likely has, at most, 256k of data available for reading/writing? Probably not. Both ProfibusDP and Modbus TCP are fast and can handle any control application.
It's difficult to believe that adding several remotes of the old system is disruptive and changing the remotes isn't. There must be many hundreds of IO in this example for them to be so concerned with prices of the remotes. Most mechanical pieces of equipment cost the same as several remotes combined. Price of automation equipment is peanuts in terms of CAPEX
It's my favorite Remote IO system. Weidmuller you rock.
This is refreshing to see. It seems a lot of organisations equate not interfering with obsolete hardware running critical systems as safe.
Hopefully, Siemens will adopt these new features & functionalities in future.
I've worked with this I/O module. Awesome video!
Thank you very much! Glad to hear that
Thank you Realpars very helpful
Glad to hear that, Wilberth!
Very good and informative video. Can we except a course on Weidmuller remote I/O ?
Love to know about this

Thank you for making such a video.🙏😊
Our pleasure!
great product from weidmuller
Thank you sir
You're very welcome!
Very good!
Glad you think so!

I'm going with no.
U think siemens support 40 year old systems. When they brake your have to upgrade. Dont get fooled by 'big companies support'.
I would like to see a video of this Remote IO being linked to Allen Bradley PLCs please.
Thanks for your topic suggestion, Darthen! I will happily go ahead and pass this on to our course developers.
Happy learning!
Good video. I have two questions:
1) What is the importance of web server?
2) Can Modbus carry more data than profibus?
Thanks.

How to work RF transmitter and receiver plz make a vidios plz..
Thanks for your feedback and suggestion, Saikumar! I will definitely go ahead and pass this on to our course developers.
How to creat different different RF weves in remote plz make a vidios
Hi Saikumar,
Thanks for your feedback and suggestion! I will definitely go ahead and pass this on to our course developers.

But it is a very important question when you are in the OPEX side. Commissioning and troubleshooting time is gold.
nice
Thank you!
Interesting, I have to compare this with the WAGO PFC200 series, especially against 750-8212/025-001.
IM-151HF....👍
Sounds like they found something that checks all the boxes. Hope that something doesn't turn out to be a big pile of crap.
Its been on the market over 5 years with thousands of global installations. C1D2, SIL2 safety ratings robust and rugged.
@@Al-yc4cn Thanks for the info. 👍
