Data type 4

This type of PLC maps a single register to 2 different registers that contain the floating-point value. For example register 235 could point to the floating-point value contained in registers 625 and 626, and register 236 could point to the floating-point value contained in registers 888 and 889. For the request sent to the PLC, the number of data registers specified will be 1 per floating point. By default the ModbusE interface expects the low order register first followed by the high order register. The Fisher Remote Operational Controller (ROC) Emulation uses this type of floating point.
