BRAD® AND DEVICENET Through its leading product lines Brad Harrison®, mPm®, SST™ and applicom®, Brad automation products give the designer and users of a DeviceNet™ system a complete Communication and Connectivity solution – from scanner through media infrastructure to I/O connection. No other supplier provides a comprehensive backbone of connectivity while giving you the power to choose other elements of the control system. You select which control engine you want, whether it be PC or PLC-based; Brad gets you onto the network. You choose which control architecture – centralized or distributed – which makes the most sense. You choose which type of motor controllers, valve banks or sensors you want; Brad insures connectivity to all these devices. Brad products can be your provider of DeviceNet connectivity from control engine to sensor. 8 DeviceNet™ Control Engine PC “soft controllers” or PLCs can act as the main control engines, taking the current I/O status off the network and solving these operations through the main control program. The new status of the I/O is then updated via the network interface to the actuators, starters and interface panels. Many times a central control engine acts as the DeviceNet “master” which initiates and controls many of the messaging sequences of the network. Scanners The scanner resides in a controller whether it is a PLC or PC, and provides a network connection. The scanner exchanges a data table, which is loaded with the various values of the inputs and outputs, with the logic controller to solve the various logical expressions. Simultaneously the operation of the master and/or slave protocols is completed. The logical expressions are then re-exchanged with the data table for communication out to the various nodes and I/O residing on the network. The scanner generally supports all standard baud rates of the network.
