This type of PLC also stores a floating point in two consecutive registers. However the request to the PLC must specify 2 data registers per floating point. The default is to expect the high order register first followed by the low order register. The GE 9070 and Micro Motion Mass Flow Meters return the bytes in this order. Modicon PLCs return the low order register first followed by the high-order register. Hence, the /swap6 parameter should be specified in the startup command file for Modicon PLCs.
