Modbus Interface Module (MIM)

Modbus Interface Module (MIM)

SonTek’s MIM enables quick and easy integration of your Argonaut-SL/SW/XR into any Modbus-enabled system using Modbus RS-232 protocol. Acting as an RTU slave device, the MIM stores the Argonaut data in a series of specific Modbus registers so that the data can be reported to the master unit in real time.

For SCADA systems compatible with Modbus, the MIM offers access to a wide range of output variables that provide a more comprehensive view of your Argonaut data.
