Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The Siemens 6ES7516-2GN00-0AB0 is a SIMATIC DP, CPU 1516PRO F-2 PN designed for the ET 200pro distributed I/O system. This central processing unit features a work memory of 1.5 MB for program and 5 MB for data, making it suitable for complex automation tasks. It integrates a PROFINET IRT interface with a 3-port switch for high-performance real-time communication and a second dedicated PROFINET RT interface. With a rapid 10 ns bit performance and a robust IP65/67 degree of protection, this fail-safe CPU is engineered for demanding industrial environments. Operation requires a SIMATIC Memory Card and a connection module.
