Section 1: General description
The mMINT (Modbus
T
Master INCOM network translator) module,
as seen in
Figure 1
, is an Eaton accessory product that will provide
communication between a Modbus RTU network and an INCOM
E
(INdustrial COMmunications) network (see
Figure 2
) . This module is
transparent to the Modbus network . It communicates to a master on
the Modbus network using the Modbus RTU (remote terminal unit)
protocol . It communicates to slave devices on the INCOM network
using the PowerNet protocol . The catalog number of this product
is MMINT .
