Hello, if I have several PLCs (example: an HMI, M580) to communicate with the m221, can I use a single read_var block and a single write_var block for communication?
Hi there! You can use the M221 as a server in a modbus tcp network then you will have multiples clients. You will need to check how you are going to use the M580 to read to the m221
@@LeTomasAHUMADA thank you very much, I have a project that I want to set up, to have 4 PLCs communicate (M221,M580, HMI, ARDUINO OPTA AND SIMATIC OIT2040). Basically, I want to create a decentralized architecture and send my data to everyone.
@@LeTomasAHUMADA i used the requet function with the M580 to the M221 where i read a variable ( ex: %MW10 ) and write on another variable( EX: %MW5 ) and on the M221 i create an animation table with these two variables. isn't there a solution where i can read and write on the same variable?
Hi A S! The initialisation is useful when you want to set in the server (slave) some values before the communication of the values defined in the channel. I strongly recommend you to use the IOscanner rather than the function blocks, please take a look in the next video: ruclips.net/video/nyXspkScEjk/видео.html
Buenas! Si usas los bloques deberías agregar una logica antes de la ejecucion para no realizar la comunicacion con el dispositivo apagado. Esto deberia ser configurable desde el hmi o en tu logica intentar communicarse x cant de veces y dejar de intentar. Solo son ideas las que puse en este comentario. Saludos
Using rs232 I need to acquire the value of a weight indicator in my Schneider MODICON M221 plc, I know that in ecostruxure machine expert basic the block for the ASCII protocol is Send Receive Message, my question is which address should I use to be able to obtain the floating value of weight that the indicator sends me
Hi Diego! The info received from the device should be converted in the plc from word to float. I believe you can assign the value to a %MW60 and %MW61 then in the code use the %MF60 (check if swap the words is needed)
Hi there! The first thing is to configure the Etherley port: ruclips.net/video/-WnZD-kgFJ4/видео.html Then you need to locate the data to be accessed by the PC. On the PC you will need a driver related to Modbus Tcp and use modus function for holding registers.
@LeTomasAHUMADA Hi! Configuration I already did . I have a custom SW with modbus driver to work with and it requires modbus device ID ( I think in my case it's 0 , when I add ip address on Modbus TCP with ID 0 ) and register number to read from device ( from 40000 to 49999 ) or write - but where I can find address of PLC variables ( like %IWN300 in IO scanner used ) . Do I need to add all commands in channel assist for my PC IP - read , write , read/write?
Hi Leandro, Thank you very much for the great videos. I am now experimenting and learning with M221. Regarding Modbus TCP IP. If I only want to Read/Write to the M221 from a another device, do I still need to set up a communication block? Is there a separate manual available for Modbus communications? Thank you
Hi there! You have different ways but the easiest is to configure the network settings on the m221, check the m221 is server then try to keep the %M and/or %MW ready for the client to read/write them.
Hi Ahmed! I have not made any video related to wireless communication probably because in the offer of this plcs (M2xx) we do not have a wireless communication card (but you can use the TCSEGWB13FA0 … i do not have it to test it ☹️) like the m580 with the PMXNOW0300. In my house i use wireless communication between some of the devices but i use a tp link mesh system and before that a vap11s-5g.
Hi Ben! I am still working in the content for the PID so far i managed to divide it like this (no video or presentation yet): _M17.1 PID in M221 _M17.2 PID Assistant _M17.3 PID Programming Part 1 (Call PID + animation table for variables) _M17.3 PID Programming Part 2 (Configuration) _M17.4 PID Implementation (Encoder + Motor + PWM Output (T)) For the implementation i was thinking in Speed control with PID but i can probably add temperature control.

Yes you can but probably it will be much better to use IOscanner. I have made this video using Serial but you can instead use MOdbusTcp: ruclips.net/video/kZul3e6Q_Rg/видео.html
