Three controllers suit automation and
safety use
Three controllers with integral Profinet interface for automation tasks have high instruction execution performance and can be programmed over industrial Ethernet from a centralised PC.
Siemens Automation and Drives has developed three Simatic S7-400 controllers with integral Profinet interface The CPU 414-3 PN/DP and CPU 416-3 PN/DP are for automation tasks, and the CPU 416F-3 PN/DP is also suitable for safety-related applications

First single processor PLC to achieve SIL1-3
The new Simatic S7-400F Fail-safe PLC is the first device of its type in the world to achieve safety integrity across SIL levels 1 to 3 of the IEC 61508 standard, for a single processor
Water industry overload protection
The Department of Regional Development in Northern Ireland (Water Services Division) has installed 41 Siemens Simocode units as part of a wastewater treatment facility for the city of Newry.
The data communications is based on the Profinet Asic Ertec 400.
In addition, the CPUs are characterised by high instruction execution performance.
The Profinet CPUs can be programmed over industrial Ethernet from a centralised PC or programming device.
Devices on the lower-level Profibus can also be accessed from here without having to reconnect the programming device.
Configuring, engineering and diagnostics are handled with Simatic Step 7 engineering software, and the safety-related section of the CPU 416F-3 PN/DP program is created with the option package Distributed Safety v5.4.
The integral Profinet Asic Ertec 400 provides high communications performance and two Ethernet ports.
This means the S7-400 controllers can be integrated into linear Profinet structures in addition to the previous hierarchical configuration.
As well as the Profinet I/O and Profinet CBA communications protocols, the CPUs also support TCP/IP, UDP and ISO on TCP.
A web server has been integrated that uses the Profinet interface to provide CPU diagnostics information over the internet and intranets.
