Telemetry Module MT-102 User's Manual - BlueNote Communications

13.2.2. Point to point communication
This is a basic minimal configuration enabling data transmission between two devices. In this
configuration, one can access internal module resources, discrete resources (inputs/outputs)
or access resources of a device connected to module's serial port or mixed access to all
above mentioned.
13.2.2.1. Using internal resources
This configuration requires two MT-102 modules, where one acts as a gateway to a
transmission system (PLC, SCADA) set in Modbus Master mode. In this case, the device
connected to MT-102 plays the role as master, sending inquiries about appropriate resources
of remote MT-102 module. The module connected to a master gives access to its internal
resources thus widening the central system.
Internal configuration of modules is as follows:
Module (A)
Set Module operating mode to Modbus RTU Slave or MT Slave
