MODIM
MODBUS INTERFACE MODULE
A PLC Interface Module for Orbit®3
Description
Solartron Metrology, the world leader in measurement
innovation, introduces a MODBUS Interface Module
(MODIM) which provides an easy to use gateway
between MODBUS PLCs and Solartron Metrology's
Orbit®3 Digital Measurement System which is a
flexible and highly accurate measuring system. The
Orbit®3 system can also interface to any sensor with
an analogue output as well as the myriad of linear
measurement sensors manufactured by Solartron
Metrology. This means that the system can be used for
temperature, pressure, force, rotary measurement and
linear displacement, providing all these process
variables to a PLC through one simple MODBUS
communications interface.
Features
MODBUS RTU up to 115200 baud
Access complex sensor networks with varying
interfaces through a set of MODBUS parameters in a
single device
Connects to all Solartron Gauging Probes,
Displacement, Orbit® LT, and Orbit® LTH.
Simple network set up via a PC application.

Note1 : The Network size refers to the Orbit Network to which the MODIM provides a gateway
Note2: The power is for the MODIM only, the Orbit Network will require additional power depending on the
modules that make up the network (Typically each Orbit module will require 60mA @ 5V DC nominal)
Refer to User Manual for Details
Note3: The Orbit Network can be set to operate in various measurement modes however the MODIM only allows
configuration of Orbit Standard mode to facilitate the two MODIM Data Transfer methods
