• 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 ION7550/ION7650 power meters. The v320 framework files are designed for use with the v321 RMICAN approved firmware. This register map is applicable to the following template revisions:  7550_v350_FAC_V3.3.0.0.2  7650_v350_FAC_V3.3.0.0.2  7650_v350_FAC-PQ_V3.3.0.0.1 (power quality framework) And the following RMICAN approved frameworks:  7550_V320_FAC
