Welcome to the forum Zymurgist
For your first question, this is a Niagara related question.
Did you proxy your MATemp point from an SNVT_temp_p or did you proxy it from nvoIO1\ui(x)? If you try the latter, you may run in to a conversion error. Setting the conversion type to linear, scale = 0 will solve that problem.
You can adjust the point's facet and set the precision to 1, then use %out.value% in your bound label.
nvoDrvStatus is a 16-bit snvt, type 83. You'll need to create an nvi of the same type in the Spyder. Right click the ControlProgram object under your Spyder and under views, pick NV configuration view. You can then click the "Add NV" button. Select network variable input, and from the NV composition check the "copy from" checkbox and select SNVT_state.B) Getting a Spyder software point (nvi) configured correctly so that I can bind it to a Yaskawa VFD snvt. For example, the Yaskawa nvo is nvoDrvStatus bit 0, a boolean point. In my HoneywellSpyderTool pallette the logical option is network input (software point). Trying to figure what properties to use (for the 1st timer) is impossible. None of the sensible options allow linking so I create test and delete and create and test and delete. Honeywell tech support has been unsupportive.
