Data for analog channels of a COMTRADE file (Pextron profile). The N3 parameter indicates a channel, from 0 (zero) to 7 (seven). Users must use a Block with up to eight Elements. The Elements must be 0: Channel's Name, 1: A Constant, 2: B Constant, 3: Maximum Channel's Value, 4: Minimum Channel's Value, 5: RPV Constant, 6: RSV Constant, and 7: Primary or Secondary Circuit (can be p, P, s, or S)

Data for Pextron profile transfer. The values for the N3 parameter can be 0: Indicates that a file was just recorded (pulse in one), 1: Number of files left for transmission, 2: Requests a collecting on the Pextron file (instantaneous), or 3: Requests the start of a random counting to collect a Pextron file (counts the time to request that collecting)

Auto Zero Bad Read. Function used when a Tag receives a ramp up-only change event (from zero to one) and never a ramp down (from one to zero). In this case, this Driver inserts an event with a value of 0 (zero) before returning each event in 1 (one)

Reading

Read (Integrity). Performs an integrity operation, requesting all points with object type × 100 + Variation declared in the N3 parameter. Users can also use a 0 (zero) variation, corresponding to any informed object, regardless of their variation. This function performs a communication (integrity) each time a Tag is read
