1. Schutzvermerk nach DIN 34 beachten Ethernet Intro

2. Schutzvermerk nach DIN 34 beachten PLC „classic“: PROs and CONs PROs: Specialized operating system, thus determinisic and failure-proof „realtime“ capability Everything on board, thus of good value Robust and suitable for industrial environment by default Fast restart after power-down, thus minimal downtimes Easy program update due to pluggable memory modules, thus very versatile Certified for many application fields Investment protection due to long availibility CONs: Proprietary systems resulting in strong dependence on certain manufacturers High effort necessary for communication with standard software packages for data management and processing causing high commissioning cost Restricted use of IT standard technology Few global players, therefore possible difficulties with availability and service

3. Schutzvermerk nach DIN 34 beachten IPC and Soft PLC: PROs and CONs PROs: Available worldwide; cheap hardware components thanks to high sales numbers Attachment to standardized, well- established operating systems, thus simple and cheap connection to standard software applications Almost no restrictions as regards memory size and processing power Simple attachment to the leading communication technology ETHERNET CONs: Risky investments due to ever shorter product lifecycles High effort for power fail safety Increased effort for fulfilling industrial requirements (e.g. no harddisks) Increased effort in the operating system area for fulfilling time critical requirements (deterministics)
