| | | The PROTECT PSC is a brand-new generation of a Safety PLC, which was especially designed to meet the requirements of modern production systems and complex individual machines. The modular system concept enables the user combining the input and output modules of the PROTECT PSC system in accordance with the needs of the specific application. In this way, no inputs or outputs of the modular safety system remain vacant, as it is often the case with other Safety Industrial plcs. This means that every user can compose "his" optimal PROTECT PSC system - an economical solution. The system however offers the possibility to integrate at any time further input and output modules in the existing system, with little effort as only the software has to be changed slightly. Currently, PROTECT PSC has two different operating modes. | | Mode 1 is the operating mode for the "hardwired" version, i.e. the system functions result from the arrangement or the order of the individual modules at the master or submaster module. The different system modules provide the user with a fixed number of inputs and outputs (in accordance with the technical specifications). Different system modules are available for digital and semiconductor input signals as well as modules with semiconductor and relay outputs. The system does not require any programming and therefore no software programming tools, e.g. PC or notebook are required. | | Mode 3 is the free programmable operating mode, in which different inputs and outputs of the entire system can be assigned by means of an IEC 61 131-compli-ant programming language (KOP). In mode 3, the user can also programme logical functions, e.g. AND/OR functions, as well as other dependencies. Furthermore, an online mode for monitoring the operational conditions of the entire system can be called up. PROTECT PSC moreover enables integrating default PLC functionalities. To this end, system modules with non-safe inputs and outputs are available for standard applications. The functions of this module can also be assigned by means of an IEC 61 131-compliant programming language (LD). Compared to all previous safety controllers, this is a new option, which enables the user omitting the standard PLC and visualising the different required machine functions by means of PROTECT PSC. | | |
