Summary

In specific project configuration/offset constellation invalid Bit is set when a FLOAT variable is seen in a screen even if all offset configuration is correct. The problem occurs when in the driver configuration it is enabled the "Offset considers data type" flag. INT, BOOL variables can communicate correctly. Also FLOAT and STRING variables display wrong values if in the AllenDF1 driver configuration it is enabled "offset considers data type" (flag). The write to the FLOAT/STRING variables is correctly processed despite the flag is active or not. The STRING data type only display wrong values if different STRING variables are shown on the same screen. When the "offset considers data type" flag is disabled FLOAT and STRING variables can be read and write correctly.
