- NDFileNexus. Fixed a bug which caused the plugin to crash with the example iocSimDetector/NexusTemplate.xml
template file. It could use a null object pointer in some circumstances.
+ - NDPluginProcess. Set default values for the recursive filter coefficients in the template file for recursive filter with
+ scale factors of 1.0. The previous defaults were 0.0 for all coefficients, which produced all zero output arrays.
+ Selecting a predefined filter did not fix this problem, because that does not set the values of OScale and FScale.
+ Fixed errors in the template file for the readback values of the filter coefficients. They had DTYP=asynInt32,
+ corrected to asynFloat64.
