Planet IMG-120T

Economical Solution for Industrial Modbus TCP/RTU/ASCII Network Integration

PLANET’s IMG-120T is an Industrial-level 2-port RS422/485 Modbus Gateway which is a bridge that converts between Modbus TCP/IP Protocol and Modbus RTU/ASCII Protocol. Moreover, an industrial IT SNMP network can be upgraded to an Industrial automation Modbus TCP/IP network without any difficulty and extra expense. The IMG-120T features a wide operating temperature range from -40 to 75°C and a compact but rugged IP40 metal housing.

The Conversion Bridge that Makes Communications Convenient

The IMG-120T is a conversion bridge that communicates well between any industrial equipment with the Modbus RTU/ASCII Protocol and the administrator workstation that runs the Modbus TCP/IP Protocol. The RS422/485 serial interface of the IMG-120T provides the Modbus RTU/ASCII operation mode and various baud rate options to meet the demand of integration between the Modbus TCP/IP Protocol, Modbus RTU Master/Slave Protocol and Modbus ASCII Master/Slave Protocol.

The advantage of having the IMG-120T is to assist users to build an industrial environment between the Modbus TCP/IP Protocol and the Modbus RTU/ASCII Protocol easily, thus offering an application solution to the industrial control equipment without Ethernet ports. Thus, the industrial control equipment can only control through an industrial PC workstation or industrial control panel.

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’s Modbus Gateway utility tool and supports PLANET’s 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°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.
