In order for HART to be active on any given channel, the channel
configuration must contain the following basic settings:
• Bit 9 (Enable HART), in the Of8h0Configuration.ChXConfigBits tag,
needs to be set. See chapter 6 for more details.
• The Of8h0Configuration.ChXOutputRange tag must be set to 2 for a 4
to 20 mA current range.
