S21260-SRS Kollmorgen Servo Drive

The S21260-SRS module automatically generates a data-flow orientated view of the PLC program (from inputs to outputs) represented by formulas and flowcharts, thus abstracting the actual sequential execution of the programme. This view is the perfect intermediate formalism between the specification and the code itself. It is independent of the programming style and type of PLC hardware on which the program runs. In addition, modules can be parameterised to use any type of document template (title blocks, symbols, …), thus ensuring consistent formatting of all documents providing fast, cost-effective control for global food packaging, renewable energy, and heating, ventilation and air conditioning applications. Modular XC Programmable Logic Controllers (PLCS) help to reduce costs and are scalable to meet the needs of individual and changing automation systems in small to medium sized systems. The modular PLCs include the XC100 and XC200 devices. For small to medium-sized control tasks, the controllers provide powerful control and integrated Canadian open fieldbus interfaces for fast, efficient communications. When additional communication and high processing power is required, the controllers have an Ethernet interface and an optional integral Web server in addition to the RS232 interface and Open Fieldbus Canada connection.

The S21260-SRS provides customisable control, and the XC controller is easily expandable with compact, high-speed input/output (I/O) modules. Up to 15 HIOC local expansion modules can be connected directly to each controller and can be used in a variety of high density channel, analogue, temperature, counter and communication modules. In addition, the XC controller has eight digital inputs and six digital outputs as standard. Ethernet access provides efficient communication between the controller and the data exchanged to higher level control systems using communication standards including Object Linking and Embedding (OLE) for Process Control (OPC). The controller utilises the IEC 61131-3 compliant CODESY programming environment to support interoperability with multi-vendor equipment. The code set has a range of features for programming, testing and debugging that simplify and organise program documentation, diagnostics and debugging. Accurate synthetic documentation can be automatically generated to aid reverse engineering, whether for new development based on legacy code or for maintenance and modernisation. Unfortunately, code is often the only documentation available, and working on an undocumented programme is always a waste of time. In addition, writing documentation manually is tiresome and error-prone. The need for a completely consistent format and the tedium of the work requires a tool-based automation approach.
