Reading and Writing

Corresponds to the C category. The status of a slave is represented using 2 (two) bits, in which the returned message may contain values 0 (zero), 1 (one), 2 (two), or 3 (three). Data type of the Value property is an unsigned integer. The meaning of each bit is the following:

•Bit 0: Reset of a slave or another situation that may have caused a loss of event data. When this bit is turned on, that is, C is equal to 1 (one) or 3 (three), a slave sends, as a response to the reading of events, the E50 event until this bit is cleared, by writing 0 (zero) to this Tag, that is, C is equal to 0 (zero)

•Bit 1: Indicates an overflow in the buffer of events of a slave. When this bit is active, that is, C is equal to 2 (two) or 3 (three), a slave always sends the E51 event as a response to the reading of events, until this bit is cleared, by writing 0 (zero) to this Tag, that is, C is equal to 0 (zero). During this overflow, a slave usually stops adding new events to the buffer, and the status must be cleared to restart storing events
