I don't know if there is any piracy law in SAUDI Arabia, coz  I'm working here right now.   I'm trying to force the management to purchase TIA pro. V15.1, for my next project. I hope so it will be approve.

Hi everyone. I didn't meant to encourage everyone for a pirated software. But I want to know what are the advantages of using genuine license TIA portal V15.1 software over the crack license? Pirated is against the law. Yes. and how about its technicalities? is there any missing libraries? and missing updates? etc. I need your inputs, because I'm trying to discourage our management of using cracked license. Thank you so much in advance...

There is no LOGO in TIA portal. nor in the software you mention, but you can link LOGO with HMI. https://cache.industry.siemens.com/dl/files/758/109747758/att_922093/v2/109747758_LOGO_light_control_en.pdf

yes it related.   because " I/O access error " occurs when you trying to access to I/O´s that are not assigned to the CPU. you can get more info in diagnostic buffer.

that's a 3rd party s7-200 simulator for micro win. it will not work all the time.

that's not very costly, you can afford it, i think so... not even 2 percent  compare to the price of TIA V15.

Base on your diagram ,it is possible but not quite accurate, since 10 minutes is long time  feedback. If "NO" other issue why not bring your acid dose closer to Alkaline dose. to reduce the response time.

Is that a brand new CPU, no previous program installed? if yes then the LEDs are normal, once you download the program and you meet all conditions you will only see the green status LED only. Your problem is that you are not establishing the network connections. Please check your firewall settings and antivirus settings. check also your LAN connections, your IP address from the PC and PLC should not be the same. in your picture the RX /Tx should be blinking, indicating a data signal exchange. try to ping also, if the CPU will response, then 100% you can download the new program.

a big possibility the file has been corrupted. try to open another file (program) and see if it can open.

I'm using virtual machine or VMware in that case...

 Classes are registered during the installation of the software in the registry. If you get an error code " class not registered " there maybe something wrong in the installation or you may have installed incompatible software.

thank you, got it.   now i need to replace my math instruction to + instead of +B. 

hi, try to replace your encoder. i don't know what's exactly the history of your machine. if that's an old encoder and working before, a big possibility that is defective, or connections and cable issue.  if your encoder is new and not exactly the same spec as the original one , then try to check again its specification and the hardware configuration in the plc. You might use different plc, but in  s7-1200 sometimes you might adjust the input filters, or sometimes i might use word math instruction to create some factors for specific application or just to meet a certain requirement.
