Consider calling a (new) function in ConcentratePumps.c that would do all of this (decides whether to accept or reject command and parks the pumps if accepting, sets reject reason code if rejecting). Function would also create and send the cmd response message and return TRUE/FALSE which would set local result here for the ack response message below.
We should reject cmd if pumps are busy/on and/or if current DG mode is fill or fault mode.
