can I ask what is going on here? I’m not a Siemens guy so I would think that a signed 15 bit 20mA value would be 32760 (or thereabouts) counts.FC105 is expecting 0 to 27648 raw values from card.
Do Siemens AI mA conversions always produce 27468 counts for 20mA (presumably for 4-20mA to eliminate 4mA offset?)?
