Hi James, Here are a couple of ways to handle this. 1)
Use autosave. The IOC will save the output voltage any time it is changed. When the IOC reboots it will restore the last saved settings, which should
match the values in the power supply. 2)
Use an asyn driver with standard asyn device support. The asyn device support for output records reads the value from the driver and if the read
returns success it sets the VAL field of the output record to this value. The driver should return success on this initial read if it was able to successfully read the power supply at initialization.
