Siemens Automation and Drives is extending its family of Opto-BERO 3RG7 proximity switches to include a new optical sensor, which has been specifically designed for the mechanical handling market.
Choosing and Using Soft Starters
Due to the improved operating characteristics they give to the equipment they control, electronic motor soft starters are increasingly widely applied. Peter Costello of Siemens explains
The Simatic S7-200 CPU 226XM micro PLC has 40 digital inputs and outputs which can be expanded by means of expansion modules to a maximum of 128 digital inputs and 120 outputs.
Analogue peripheral devices and temperature measurement modules can also be connected by means of expansion modules.
Two separate interfaces permit the simultaneous operation of the device in two different networks.

PLC achieves SIL1-3 Safety Standards
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.
Therefore, one interface can be used in a Simatic S7-200 network and the second interface in a Simatic S7300/400 network as a slave-MPI interface.
Alternatively, each interface can also be parameterized as a freely programmable device interface and can control drives, modems or printers with ASCII protocol.
Using communication expansion modules, the CPU 226XM can also be used as a slave in a Profibus-DP network and as a master in an AS-i network.
The CPU 226XM has the same extensive instrument set as the 224 and 226 CPUs, including 32-bit floating point arithmetic, which has trigonometric functions and integral PID controllers.
The Simatic S7-200 CPU 226XM micro PLC is available as a direct current version with 24V DC feed and 24 V DC transistor outputs, and also as an alternating current version with 230V AC feed and relay outputs.
Due to its wide input voltage range of 85 to 264V, the AC variant can be used all around the world.
Like all S7-200 CPUs, the user can program and configure the new device using the Step7-Micro/WIN software in his preferred form of representation: ladder diagram, statement list or function block diagram.
Several projects can be processed in parallel.
Drag-and-drop functions using the keyboard and mouse, with cutting, copying and pasting, even across several networks, considerably simplify program generation.
Step7 Micro/WIN offers convenient search and replace functions as well as printing functions.
For each network, a symbol information table can be displayed in the ladder diagram and function block diagram with the absolute addresses used in the network and their symbolic names and comments.
Programs for the CPU 226XM can be edited using MicroWIN V3.1x, even during runtime.
