KB-35875: Reading negative values with Siox driver.

Question:

When using Siox driver, why does SCADA display an approximate value of 65535 and not the negative values read in the device?

Solution:

This happens because Siox driver cannot currently support negative values, only WORD-type value (unsigned 16 bits). So, the diver will adapt a signed value to an unsigned type, thus generating this type of variable.
