    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?

    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:

    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?

    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.

    What is your wiring?  The Omron RS232 port is non standard wiring.

    AC01 is an incorrect hostlink command.:shrug:  You will not get a response.

    I talk with my professor  and he say that i must sent "AC01" hex and wait for response. It will work like:

    Please use the documentation that IO Rack sent you. 

    I use this documentation and i can't find answer.

    When i talked with my professor he said i haven't must sent " @ " and  my command would looks like:

    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?

    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?
