Special reading and writing functions are this Driver's functions not defined by the standard Modbus protocol. They were developed to meet specific features of certain devices, or else to provide, in a standardized way by this Driver, features not available in the standard protocol. This Driver, in its current version, includes the special functions described next.

Reading Functions

•65 03: Mass Memory Reading (ABB MGE 144), described in details on topic Reading Mass Memory Registers from ABB MGE 144 Meters

•GE SOE: Event Reading (GE PAC RX7 Systems), described in details on topic Reading an Event Buffer from GE PAC RX7 Controllers

•SP SOE: Event Reading (Schneider Electric SEPAM series Relays), described in details on topic Reading Events from Schneider Electric Relays from SEPAM 20, 40, and 80 Series

•GenSOE: SOE reading with a generic algorithm, implemented by a resident software in the slave device (PLC), described in details on topic Elipse Software's Generic SOE Reading Algorithm

Writing Functions

•65 01: Restarts, that is, performs a reset operation, a power meter (ABB MGE 144). This command is sent as a Tag's simple writing command (Write). Tag's Value field is ignored by this Driver and can be kept in 0 (zero). For more information, please check that device's manual

•65 02: Zeroes the maximum and minimum memory (ABB MGE 144). This command is sent as a Tag's simple writing command (Write). Tag's Value field is ignored by this Driver and can be kept in 0 (zero). For more information, please check that device's manual

Notice that this Driver's special functions, except for the writing function 65 01, are directly or indirectly related to mass memory reading of registers of their respective devices. For more information, please check topic Mass Memory Reading. For a description on how to configure operations and Tags using these functions, please check topic Configuration.
