• The register map of an ION meter has a part you configure (the Modbus Slave modules) and a fixed part. This map is the default Modbus Slave module map of the template revisions named by the manufacturer; if the meter has a custom framework, the registers can be elsewhere.
• Addresses are the 4xxxx register numbers of the manual minus 40000, as sent on the wire (register 40011 is address 10). Values are read with FC03; FC16 writes the registers marked read/write.
• 32-bit values have the high-order register first. A value shown with a scale is the register divided by the scaling of the module (11982 with scaling 10 is 1198.2). The units are inferred from the register labels.
• Unmapped registers between blocks read as 0xFFFF.
• Not in this map: the 32-bit modulus-10000 (M10K) energy registers, and the common Modbus registers for setup and control.
• Default template revisions: This table outlines the default data registers available on the ION7300 series power meters. For further information on accessing configuration and control registers using the Modbus protocol, please see the ION7300 series Modicon Modbus Serial Communications Protocol document. This register map is applicable to the following template revisions:  7300_FAC-4WYE_V2.2.0.0.0  7330_FAC-4WYE_V2.3.0.1.1  7350_FAC-4WYE_V1
