DeviceMaster UP Modbus Solution Examples UP T This document includes a number of Modbus connectivity examples which are intended to help the system e integrator or plant engineer determine how to set up i installations. These examples include information such i as the recommended chassis and Modbus firmware for a each configuration. Information on how to configure the e functionality for each particular DeviceMaster is left to the f User Guide Manuals. U Due to flexibility of the DeviceMaster UP Modbus firmware D applications, it is not possible to show every possible a Modbus solution. The Modbus Router and Modbus/TCP firmware applications provide the ability to create either very simple or very complex Modbus installations. For instance, you can combine more than one of these connectivity solutions onto one gateway or use several gateways to build a Modbus network. (A Modbus network typically involves multiple gateways providing communication between Modbus controller(s) and device(s) on a network.) When setting up your Modbus installation, please keep the following in mind: • When using either Modbus Router or Modbus/TCP firmware, all Modbus masters can communicate to all slave devices. For example, you can have multiple serial and Modbus/TCP masters communicating to the same or different slave(s) at one time. • When using Modbus/TCP firmware, both Modbus controllers and applications can communicate to a single raw/ASCII device at the same time. • Modbus messages are automatically converted from one format to another. For instance, you can connect Modbus/RTU masters to Modbus/TCP or Modbus/ASCII slaves and the gateway automatically performs all conversions and message verification. • Each serial port or Ethernet TCP/IP device interface is individually configurable. That allows: o For Modbus/TCP and Modbus Router firmware, multiple serial master or slave devices of either the same or different Modbus type can be attached to the same gateway. o For Modbus/TCP firmware, each raw/ASCII serial port or Ethernet TCP/IP device interface can operate in different receive and transmit modes. (i.e. One can operate in master mode while others operate in slave or master/slave mode.) If you have an installation that is not covered by these examples or if you are not certain how to set up your environment, please call the Comtrol customer support staff for more information.

3. You have a Modbus/TCP Master/Slave Controller This typically includes full-featured controllers such as PLCs, OPC Servers, SCADA Systems, HMIs and applications that can communicate simulataneously as a master and a slave via Modbus/TCP. Utilizing Master/Slave functionality allows the controller and the DeviceMaster UP to operate as peers. Due to the nature of master/slave connectivity, the functionality for Modbus/TCP master/slave controllers is limited to communicating to raw/ASCII devices. a. And you have Raw/ASCII Serial Device(s) b. And you have Raw/ASCII Ethernet Device(s)
