Communication with PLC devices by the Emerson company
) manufactures meters, sensors and also Smart Wireless Gateways
This device creates a Wireless
network that can be used for reading data from meters connected to such network and then pass the data forward via OPC
protocol for furher usage.
Communication by the Modbus protocol - Smart Wireless Gateway
The Smart Wireless Gateway
device supports communication by the Modbus protocol
This protocol is not set in the device as default. Therefore it is necessary to enable this protocol before the communication starts. For this communication in the PROMOTIC system can be used:
For this driver, it is recommended to set the configurators:
The Modbus registry address of analogue values starts at address 40000
(based on the documentation).
However in reality these values are available at address 0
and higher. For example the value on Modbus registry at address 40010
reads in the PROMOTIC system system from address 10
