Diagnostic BTR.

Relay/setpoint BTR.
Rung 2:21
Command BTW.
Rung 2:22
Configuration BTW.
Rung 2:23
If the setpoint counter done bit
is set, the last setpoint BTW has
occurred and was followed by a
diagnostic BTR. If the
diagnostic table indicates a
successful setpoint BTW,
setpoint mode is done. The
setpoint mode bit is unlatched,
and the run mode bit is latched.
