Modbus/TCP makes the definition of master and slave less obvious because Ethernet allows peer. This device has been spectaculary successful with large corporate clients who want to be able to integrate their BMS/EMS with their billing meters as the first communications port remains as an EDMI Command-Line port (2-wire RS485). The master will write and read data to a slave devices registers. (2) When HRT-7(3)10 runs in Operation mode, it will execute all polling.

The Modbus address can also be pre-programmed in factory to customer requirements if necessary. Q06 : How to read HART device CMD 3 data with standard format by Modbus. 000-Tx: 7F 03 00 00 00 04 4E 17 > command line with 2 byte CRC (4E 17). For each window you simply specify the Modbus slave ID. With the multiple document interface you can monitor several Modbus slaves and/or data areas at the same time.
#Cmd modbus poll serial number#
The embedded processor in the Modbus Duo talks directly to the meter and automatically adopts the last two digits of the meter serial number as the device Modbus address as well as interrogating the meter to allow acces to the TOU resgisters and load-profile details. Modbus Poll is a Modbus master simulator designed primarily to help developers of Modbus slave devices or others that want to test and simulate the Modbus protocol. This allows a Building Management Systems (BMS) and Netstream, or an Energy Management Stsrem (EMS), to concurrently access the same EDMI Atlas Meter for real-time reporting of meter parameters. The 1-based number defines the coil or register. The address format follows the Modicon PLC convention of a data table number, followed by a 1-based number.
A “plug and play” device that enables customers to intergrate their meter systems with building management systems by converting the second communications port of EDMI "ATLAS" series meters EDMI Command-Line output to 2-Wire MODBUS RTU. The Modbus PLC Data Address Format is a string that defines the location of data in a Modbus PLC.
