This Driver allows defining, on operations, special reading functions for collecting mass memory from slave devices. Such functions do not exist in the protocol, and imply in using specific algorithms for reading events from devices, which may read or write in several registers, by using one or more protocol functions.

Callback Readings

Starting with version 2.08, this Driver implements callback readings, a feature available in E3, starting with version 3.0, and in Elipse Power, which optimizes performance of mass memory readings. With this feature, an application delegates to this Driver a Tag scan for reading mass memory events. In other words, an application does not need to keep asking this Driver at each scan period. Instead, this Driver performs a verification of new events on a device and collects events as soon as they become available, and sends them to the application.

Special Functions for Mass Memory Readings

On the current version of this Driver, the following functions for reading sequences of events (SOE) are supported:

•GE SOE: Performs event collecting from GE PAC RX7 PLCs. For more information, please check topic Reading an Event Buffer from GE PAC RX7 Controllers

•SP SOE: Collects events from Schneider Electric SEPAM series 20, 40, and 80 relays. For more information, please check topic Reading Events from Schneider Electric Relays from SEPAM 20, 40, and 80 Series

•GenSOE: This function uses a generic Algorithm created by Elipse Software, Elipse Modbus SOE, which can be used by most Programmable Controllers. It requires the creation of an analogous programming procedure on PLC's programming (ladder). For more information, please check topic Elipse Software's Generic SOE Reading Algorithm

•65 03: Special function for reading mass memory events from ABB MGE 144 meters. For more information, please check topic Reading Mass Memory Registers from ABB MGE 144 Meters
