Modbus TCP
Device supports Modbus protocol for communication with SCADA systems. Device use
Modbus TCP protocol. TCP port is set to 502 by default. Port can be changed using TSensor
software or web interface. Only two Modbus clients can be connected to device at one
moment. Modbus device address (Unit Identifier) can be arbitrary. Modbus write command
is not supported. Specification and description of the Modbus protocol is free to download
on: www.modbus.org.
Supported Modbus commands (functions):
