This chapter introduced how to use software to manipulate the meter through the

communication interface.

The chapter’s contents include MODBUS protocol, communication format, application

details of AcuRev 1200 series meter.

5.1 Modbus Protocol Introduction

1. Transmission mode

The mode of transmission defines the data structure within a frame and the rules used

to transmit data.

▲

Coding System 8 bit

▲

Start bit 1 bit

▲

Data bits 8 bit

▲

Parity No parity / odd parity / even parity

▲

Stop bit 1bit or 2bit

▲

Error checking CRC

2. Frame

When data frame reaches the terminal unit, it goes through the unit via a special

"port", the unit removes the data frame's header, reads the data, if there is no error, then
it implements the data's task. Afterwards, the unit puts its own data with the acquired
header, and sends back the frame to the sender. The response data frame contains: Address,
Function, Data and CRC Check. Any error will cause a failure to respon
