    I am trying to build up my own 3dof simulator by using PLC. However, there are 2 quesitons confuse me and ask your support:

    1. Normally, to communicate with PLC, it is naccessary to using Communication Protocol. e.g. modbus etc.
    So what Communication Protocol does Simtools V3 exactly used for communication?

    2. I read the broucher of Simtools V3 about interface output. If I just use the type<axis1a><axis2a><axis3a><axis4a>, does is means I will receive four numbers among 0-255. Or I will receive 4 char type string?

    When selecting 8 bit output, you will get 4 chars as a string if you choose binary output, and 4 number between 0-255 all stuck together as a single sting when send as decimal.

    Thank you for the reply firstly. However, as the freshman of C++, know little about C++(mainly work on PLC programing normally). It is hard to compile API by using C++, so~~~~can I just use exist serial interface for my own simulator or it is must to custom an interface for DIY simulator?

    Lookog forward to your reply. Thanks.

    em.... I have read all related FAQ about API. It seems there is no answer about my question 1. For PLC communication, it is needed to have a "Communication Protocol". So how or where can I define the communication method in simtools? or how can I define the communication method when compile an interface?

    Do you connect the PLC to the PC thru a networking cable or serial cable? And then what does a move axis command look like?

    The first thing to check is the interface setup for SimTools v3. Please click "Test Settings" for the interface you setup, does your simulator move as expected with the test sliders?

    If the game is running on the headset itself, you will need the console version of the the plugin here.
    https://simtools.us/plugin/?varname=221&color=0e97dd

    With the game running on the headset, go into the games settings, and enable telemetry with the ip address of the computer running SimTools, and the port set to 4123. Then simply double click the play button on the console plugin in SimTools and you should get data.
    Please let me know how it goes.
