Truncated 16-bit signed integers?

Thank you very much for you inputs! The example project helped me a lot to get it working!

How I got it running:

• First I downloaded your Sii .bin from the SBS625 project file onto the Ethercat interface card with "ethercat sii_write".
• Checked that the SM and PDOs are configured correctly with "ethercat pdos".
• Then i realized that the Ms300 card is still in init and the error flag is shown.
• I tried to get some more debugg information by attaching the USB cable. As soon as I touched the lid, the red error led disappeared ^^ So there was also a connection issue between the interface cards connector and the cable to the vfd..
• With your driver it worked perfectly (after I realized that the start up time is in ms and not seconds ^^)
  
  Falls irgendwie möglich db1981, würde ich dir gerne einen Kasten Bier spendieren Habe einige Abende mit debuggen verbracht. Danke!
