  • Planet 1-port RS232/422/485 Modbus Gateway with 1-Port 100BASE-FX SFP | MG-115A

    Standard Modbus TCP/RTU/ASCII Network Integration
    PLANET MG-115A 1-port RS232/422/485 Modbus Gateway supports the standard Modbus Protocol, which makes it possible for converting any Modbus Protocols between Modbus TCP, Modbus RTU, and Modbus ASCII for all supported hardware interfaces. Its serial protocol can be used for industrial automation where SCADA or HMI system is in place. Moreover, its network integration can be upgraded from the SNMP network to the automated Modbus TCP network, which brings interconnection over Ethernet longer distances, thus making a network infrastructure more flexible. 


    A Conversion Bridge for Flexible Network Deployment

    The MG-115A can be a conversion bridge between the equipment with the Modbus RTU/ASCII Protocol and the administrator workstations that run the Modbus TCP/IP Protocol. The RS232/422/485 serial interface of the MG-115A 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 MG-115A is to assist users to build an environment between the Modbus TCP Protocol and the Modbus RTU/ASCII Protocol easily, thus offering an application solution to the control equipment without Ethernet ports, and the control equipment can only control through a PC workstation or control panel.

    In addition, the effective integration solution of Modbus Ethernet devices, Modbus serial equipment or multi Modbus master / slave in a hybrid network brings the following:

    Master mode supports up to 32 slave TCP connection requests
    Slave mode supports up to 32 TCP master connections


    Remote Management 

    The MG-115A makes the connected Modbus RTU/ASCII equipment become IP-based facilities and is able to connect to the Modbus TCP/IP network via its R232/422/485 serial interface and 100BASE-FX Ethernet port. It provides a remote web management and telnet Interface for efficient remote network management. The MG-115A 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 MG-115A.


    Modbus Serial Port State Monitoring

    The MG-115A shows the details of the total bytes transmitted and received on the RS232/422/485 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 MG-115A via the single RS232/422/485 serial interface.

    Fiber-optic Link Capability Extends the Range of Network Deployment
    The maximum distance between two IP devices via Ethernet UTP cable is 100 meters. To flexibly extend the deployment range of Modbus gateway, the MG-115A’s SFP slot supporting 100BASE-FX SFP modules, and more can reach a transmission distance of up to 120km.

    Easy Chassis Installation
    The MG-115A can be used as a stand-alone unit or as a slide-in module to the PLANET Media Converter Chassis (MC-700 and MC-1500 chassis). The media chassis can assist in providing DC power to the MG-115A and can be DIN-rail or wall mounted for efficient use of cabinet space, without the need of replacing the existing serial equipment and software system.


    Applications

    RTU/ASCII Master to Multi Modbus TCP/IP Slaves
    The MG-115A can act as a bridge between the RTU/ASCII master equipment and the multi-TCP/IP slave equipment in a Modbus TCP/IP networking environment to control multi-TCP/IP slave equipment via the RTU/ASCII master equipment.


    Multi Modbus TCP/IP Master to RTU/ASCII Slaves

    The MG-115A can operate as a bridge between the multi-TCP/IP master equipment and the RTU/ASCII slave equipment in a Modbus TCP/IP networking environment to control the RTU/ASCII slave equipment via the multi-TCP/IP master equipment.
