SIMATIC S7-1500 CPU 1516-3 PN/DP (6ES7516-3AN02-0AB0)

The CPU 1516-3 PN/DP is a mid-to-high performance standard CPU of the SIMATIC S7-1500 modular controller family, programmed in the TIA Portal. It offers 1 MB of work memory for the program and 5 MB for data, with bit instruction processing times of roughly 10 ns. It has three communication interfaces: two PROFINET ports on one interface with an integrated two-port switch, a second separate PROFINET port, and a PROFIBUS DP master interface. An integrated web server, OPC UA server capability, motion control support for multiple axes and integrated system diagnostics with plain-text display messages are included. The CPU occupies a slot on a mounting rail with a power supply module and takes a SIMATIC memory card. It is aimed at medium to large machines and process lines with demanding speed, communication and motion requirements.
