Discrete I/O connected direct onto Profibus-PA Input and Output Function Blocks, including Flexible Function Block (FFB) for logic execution Power, Control and I/O integrated in the same hardware Mix Profibus with conventional devices Reduce wiring cost
DC303 Description Until all types of devices are available with Profibus-PA systems, they will have to be a hybrid nature accepting both Profibus and conventional signals. A mixed traditional and Profibus environment is inevitable during the transition to a Profibus technology. DC303 Remote I/O makes integration of Profibus and conventional I/O easy. Discrete devices such as pressure switches, push buttons, on/off valves, pumps and conveyors are integrated to the system over the Profibus-PA field-level network using DC303. It is a single integrated easy to use piece of equipment including power, control, networking and I/O under one compact device requiring less panel space than other solutions. The DC303 is an integral part of SYSTEM302 but also integrates into other systems supporting Profibus. Easy Installation The DC303 Remote I/O units can be distributed into the field where they are mounted close to the conventional devices without the need to run the conventional wiring to the control room. The unit may be installed close to the sensors and actuators, thereby eliminating long wire runs and associated marshalling panels and cable trays for the conventional I/O, with subsequent savings further reducing overall system cost. Use DC303 to make it possible to distribute I/O at various locations in the field and connect them via Profibus-PA. DC303 is ideal to connect motor control centers, variable speed drives, and electrical actuators and motor operated valves to Profibus-PA. The DC303 is a simple low-cost DIN-rail mounted unit. It can optionally be supplied preinstalled in an enclosure ready for field mounting. Easy Configuration The DC303 is fully configured through the SYSTEM302 or any other Profibus configuration tool based on EDDL or FDT/DTM. Function Blocks The DC303 has 16 Discrete Input (DI) blocks and 8 Discrete Output (DO) blocks. Conventional discrete I/O now works together with pure Profibus devices on the same network and in the same loop. Output function blocks include standard Profibus-PA safety mechanism in case of failures. Inputs and outputs are isolated from each other and the Profibus network in groups of eight channels. LEDs are used to indicate active outputs and inputs. 2
Description DC303 Function blocks PHY DISCRETE INPUT DISCRETE OUTPUT TRD Block This block contains data that is specific to the hardware that is associated with the resource. The DI block takes the manufacture's discrete input data, selected by channel number, and makes available to other function block at its output. The DO block converts the value in SP_D to something useful for the hardware found at the CHANNEL selection. Transducer block that allows the inputs and outputs to interface with discrete function blocks, and allows setting the FFB to provide logic such as AND, OR, XOR, NOT etc. as well as SR flip-flops, RS flip-flops, Timer On Delay, Timer Off Delay, Timer Pulse, Counter Up, Counter Down. Based on structured text language, provides an easy way to generate the logic implementation.
