Hi Guys, Does anyone here know if there is a possibility to communicate with a Beckhoff HMI using Modbus TCP? I currently have a controller with Modbus I/O registers and I want the Beckhoff HMI to r/w to it. Any suggestions other than OPC? ~Chaca.

Hi Jim, This problem has been reported to 3S. This is an issue with CoDeSys. Once a value is forced and the force is removed from the bit, the bit remains set until you force it off again. Apparently, this issue is going to be corrected in the new version of CoDeSys. Chaca

Thanks Kseniya & Mr. PLC!

Hi Turck Experts! I am curious to know if the BL67-RS232 Module will take a modbus signal from an instrument and pass it out using the BL67-PG-EN Modbus TCP gateway. Thanks!

sorry guys quick note...the input modbus signal is an RTU/ASCII if you already didn't know that!

still no reply in either forums.

Hi Guys/Gals...I am looking for some sort of a tool or utility or anything that would assist me in converting an S7 project to and IEC61131 compatible code. Any suggestions? Cheers!

Here is the Omron CX-1 Code. I still didn't have a chance to do that in CoDeSys. Han_Modular_ID_Module_I2C_protocol.zip

Alright guys/gals, here is a challange for all of you CoDeSys Guru's out there. Write an I2C Bus Protocol Driver using CoDeSys in ST using standard I/O's of a PLC. For example, you can tag the SCL signal to one of the PLC outputs and the SDL to one of the PLC inputs/outputs (share the same signal). All you have to do is write one byte of data to the I2C EEPROM and read one byte of data out of the EEPROM. I have attached a PDF file that contains the specs on this module and the pinouts for clarification. I just bumped into this interesting protocol. I haven't written anything for it yet. Let me know what your thoughts are. I will start writing hopfully later on this evening. Have fun and let me know what you come up with! PS: Just remember, there is a Read or Write Initialization byte that has to be transmitted before the actual data byte is written or read. HAN_ID_Module_Flow_Chart.pdf

Well Guys, If you need a programming cable for the PS3 you will need a special RS232-RS485 converter, because Moeller uses a special protocol called Suconet K to communicate with these PLC's. The only one converter that I found that actually works is a converter made by Omega UK. It supports the Suconet K protocol 187.5kbps. If you guys need S30 software or documentation, you can get it free from Technical Support desk in Canada. Try to call them and they will email you the software for free. I hope this helps! Cheers!

Hi Manuel, I know this site does not allow any posts on password cracking, however, just to let you know, Moeller's MFD Titans can not be password cracked. Even if you sent it to the factory, they can not retrieve the password, they will need to reflash the program memory, which will erase the program. I suggest trying to get in touch with the machine builder and see if they will give you the soft copy of the program. Good Luck!

Here is the SLC Code. Did anyone resolve this in CoDeSys yet? Read_Harting_ID.RSS

Hey Tony, I just finished coding it in SLC500, now I am going to work on it to write in CoDeSys. Will post it when ready...just curious to see how many people are comfortable with St. Cheers!

Hi Guys/Gals, I would love to hear about Turck's new Programmable Gateways (BL20's and BL67) that utilize CoDeSys IEC61131. Does anyone have any experience with these units? ~Chaca

Hi Nick, No specific questions as such, I just wanted to see "Turck" CoDeSys awareness at Mr.PLC. Thank you for your reply. ~Chaca

Guys, the only reason why B&R is not known much to public is because B&R doesn't sell PLC's/HMI's on their own, they do complete turnkey projects. It is the largest privately owned Automation Company in the world. The reason why no one talks about it, especially integrators is essentially because of the way they do business. There products are completely catered to the end users' needs and thats why you don't hear many people talk about it.
