Both registers must be accessed in oneoperation, using Function Code 04.Table 19. Product ID Command Descriptions.Name Register Number(decimal) Register Address(hex) FormatProduct ID/Breaker Product ID 6255 186E EncodedThe Product ID is encoded as follows:• Product ID = 3 – b15 .. b10 of Register Address 0x186F;• Communication Version = 1 – b9 .. b6 of Register Address0x186F; and• Division Code = 35 – b5 b0 of Register Address 0x186F.The Breaker Product ID is encoded as follows:• Product ID = 1 – b15 .. b10 of Register Address 0x186E;• Communication Version = 1 – b9 .. b6 of Register Address0x186E; and• Division Code = 32 – b5 b0 of Register Address 0x186E.5.6. Snapshot EnergyThe PM3 Modbus Module supports a control command to cap-ture energy. A write to Register Numbers 2911 (Address 0x0B5E)and 2912 (Address 0x0B5F) using Function Code 16 (0x10), WriteMultiple Registers, is used for this purpose. The Modbus commandregisters and assignments are shown in Tables 20 and 21.ote:N The effect of this command is the same as the Snapshot Energy com-mand (see Section 5.7).Table 20.
