Dynamic Fluid Measurement E-CHART Manual Modbus Data – 4-55
DATA PACKET
Reading Event/Alarm Register
The Modbus request to read the event log uses the standard read function code 03 and
the register number 32 (20 Hex).
After receipt of the acknowledge packet, the ECHART will reset its event pointer to the
next packet of events. After an event pointer has been reset, the master can not go
back and collect the previous events.
This process is repeated until the ECHARTs event buffer is empty of all events that
occurred since last collection.
