Planet Networking & Communication IMG-120T User Manual page 8

In addition, the effective integration of Modbus Ethernet devices, Modbus serial equipment or multi Modbus
master/slave in an industrial hybrid network brings the following:
 Master mode supports up to 32 slave TCP connection requests
 Slave mode supports up to 16 TCP master connections
Remote Management
The IMG-120T makes the connected industrial Modbus RTU/ASCII equipment become IP-based facilities and is
able to connect to the Modbus TCP/IP network via its R422/485 serial interface and 10/100BASE-TX RJ45
Ethernet port. It provides a remote web management and telnet Interface for efficient remote network
management. The IMG-120T also provides PLANET Modbus Gateway utility tool and supports PLANET Smart
Discovery utility to help network administrator to easily get the current IP subnet address information or change
the IP subnet address setting of the IMG-120T.
Modbus Serial Port State Monitoring
The IMG-120T shows the details of the total bytes transmitted and received on the RS422/485 serial interface,
and the detailed total number of frames transmitted and received on the remote web/telnet management
interface. This function allows network administrator to check the status and statistics of the IMG-120T via the
single RS422/485 serial interface.
Stable Performance in Hardened Environment Design
The IMG-120T provides a high level of immunity against electromagnetic interference and heavy electrical
surges which are usually found on plant floors or in curb-side traffic control cabinets. Its operating temperature
ranging from -40 to 75 degrees C allows the IMG-120T to be placed in almost any difficult environment.
The IMG-120T is equipped with a compact IP40-rated metal case that allows wall mounting for efficient use of
cabinet space. The IMG-120T also provides an integrated power supply source with wide-ranging voltages (9 to
48V DC) ideally suitable for worldwide operation with high availability applications.
