Posted 25 Oct 2018 (edited) Hi, I write app to smartphone to communication omron CJ1m and Android. I want to connect devices by standard bluetooth. I plug in bluetooth adapter directly to omron RS232. I want to ask you, how i can connect by FINS command. Bluetooth device baud rate is set 9600. If i connect to omron, i sent code: "AC01" and i sent how long as omron return me "AC01" ?? And what's next command i sent? If I want read CIO 10 i sent: "0101B000000A" ? and FCS and "*" ?? how i calculate FSC? Is it XOR my data sent? Edited 25 Oct 2018 by Dareko009 Share this post Link to post Share on other sites
Posted 26 Oct 2018 Here is an FCS Calculator at Mr PLC's downloads section. http://forums.mrplc.com/index.php?/files/file/174-fcs-frame-checksum-calculator/ The manual that want to reference is the CS/CJ Communications Commands Reference Manual W342. You'll want to use Host Link protocol for RS232 communications. FINS is used for Ethernet. Share this post Link to post Share on other sites
Posted 26 Oct 2018 Thanks for answer. I look for answer to my question in this documencation and i can't find it or i can't understand it. In this documentation i can't find anythink about command "AC01" to check connection. I search answer in Net and i found http://www.tri-plc.com/HostlinkE10.pdf In 1st point is Poin-to_point communication and what i know about my communication it will look at this... But i don't know what i should write in Header? And my code would like: Header + Command + Terminator? And what about reply? Share this post Link to post Share on other sites
Posted 27 Oct 2018 Quote If i connect to omron, i sent code: "AC01" and i sent how long as omron return me "AC01" ?? AC01 is an incorrect hostlink command. You will not get a response. To read the first CIO word. Try "@00RR0000000141*CR" Quote I plug in bluetooth adapter directly to omron RS232. What is your wiring? The Omron RS232 port is non standard wiring.

Posted 27 Oct 2018 Please use the documentation that IO Rack sent you. You are trying to use a different manufacturers documentation other than Omron hostlink. http://forums.mrplc.com/index.php?/files/file/620-w342-e1-09-sysmac-cscj-series-communication-commands/ CS/CJ Communications Commands Reference Manual W342.

I talk with my professor and he say that i must sent "AC01" hex and wait for response.

Posted 27 Oct 2018 Quote This is for the peripheral port. @Jay Anthony Can you tell me how would like command look if i connect to PLC by peripheral port? Maybe i don't understand my professor and he want connect to PLC by peripheral port because he said about "AC01" and simple command FINS. Share this post Link to post Share on other sites
Posted 27 Oct 2018 The peripheral port is for programming. use the serial port with the command I gave you. Share this post Link to post Share on other sites
Posted 27 Oct 2018 What about ToolBus? Would it be easier? Share this post Link to post Share on other sites
Posted 27 Oct 2018 Toolbus is not documented. What's wrong with Hostlink?? Share this post Link to post Share on other sites
Posted 28 Oct 2018 (edited) Quote Toolbus is not documented. What's wrong with Hostlink?? Probably nothing. But i asked my professor and he want use ToolBus communication. In my program i will use only command to read and write word from and to omron. In this forum i found, ToolBus command would look like: Quote Message format: Toolbus Header, FINS Header, FINS Command, Checksum. Where: Toolbus Header - AB00xx xx - number of following bytes in message including checksum - number of bytes FINS Command and Checksum ? FINS Header - if i connect whit PLC directly, i can skip FINS Header ?? FINS Command - it is standartd FINS Command, eg 0101 - memory area read + B0 - memory area code(word CIO area) + 000000 - read adres (word CIO 0), Chcecksum - sum all bytes of message to form 16 bit (two byte) checksum - it is sum with Toolbus Header or not?? This message is sent by byte? Edited 28 Oct 2018 by Dareko009 Share this post Link to post Share on other sites
Posted 29 Oct 2018 Indeed Toolbus ain't documented, but using the Multiway program from Omron France, we can practically reverse engineer it. Granted you are a student, I'm sure you have the time for doing that. However, as Jay mentioned it is not really wise to do so. It's kind of wasting your time reverse engineering something that is undocumented, while you have something else that is already documented properly with the exact same usage (HostLink in this case). And guess what? The said "AC01" command was actually documented here : https://www.myomron.com/index.php?action=kb&article=34 Surely it is not documented properly. If you want to try the command again, try sending "AC01" not as a String (in which you are sending 41 43 30 31 hex bytes), but send them as a raw hex bytes (so you are sending AC 01 hex bytes). I don't know whether that'll work or not since I never tried it myself. Good luck. Share this post Link to post Share on other sites
Posted 20 Jan 2019 Hey, sorry that i answer now. I made app to Android to connect with Omron CJ1m but I found problem and i can't solve that. If I write data to CJ1M e.g. 0x0033, PLC has write 0x0013. I send command by ToolBus and it looks like: This command is like FINS command in documentation OMRON. Can you any suggestion?

Posted 20 Jan 2019 Quote 0x0033 Not a valid Command Code Quote PLC has write 0x0013 End Response indicates invalid command code.

Posted 21 Jan 2019 But i know, i use to write command 0102 and data is 0x0033. I have end code 0101, that i Save correct but than i read this memory and it is 0x0013.. Share this post Link to post Share on other sites
Posted 21 Jan 2019 Quote i use to write command 0102 and data is 0x0033. What register are you writing? Quote but than i read this memory and it is 0x0013.. Are you writing to actual I/O? If so the hardware may be turning off the sixth bit, Is there code in the PLC? If so, the program could be turning off the sixth bit. Try the command with the PLC in program mode.
