I have seen a couple of places where a the time on a Toff timer is coming from a HMI parameter page where the user (with the right authority) can type it in. This value is then stored in a DB in the form of a DBW. The DBW is then used as Toff time on the timer. My questio...
The following section is fundamental to understanding the technological and pedagogical characteristics surrounding MOOCs. We present those that seem to be the most important for a general understanding of the dynamics of MOOCs. 2.1 Evolution of MOOC In 2008, George Siemens and Stephen Downes published...
I've wanted to broaden the selection of products (hardware, software or both) that I offer for RoadTests. We've done a lot of great test equipment lately. And I've tried to expand our dev board offerings with FPGA-SoCs. But this one is a little different
A mainframe computer is critical to commercial databases, transaction servers and applications that require high resiliency, security and agility. Since the advent of the internet and the rise of cloud computing, some may think of the mainframe as a tech dinosaur. On the contrary, the mainframe ...

Other significant manufacturers in the mainframe market during the 70s and 80s include Fujitsu, Hewlett-Packard, Hitachi, Honeywell, RCA, Siemens and Sperry Univac. During this time, the mainframe industry continued to advance with smaller machines, I/O performance improvements, more significant memory...
An ampere is the unit for electric current, which is the number of electrons flowing through a circuit. An ampere is the current produced by a force of 1 V acting through aresistanceof 1ohm(Ω). Put another way, a potential of 1 V appears across a resistance of 1 Ω when a current...
one derived unit is the newton, which can be expressed in terms of base units as 1 kg m/s2. Other derived units include the hertz, the pascal (unit of pressure or stress), theohm, thefarad, the joule, the coulomb, the tesla, the lumen, the becquerel, the siemens, the volt and th...
What is a chiplet? A chiplet is a small, modular chip that performs a specific function very well. For example, a chiplet can be a processor core, a memory block, an I/O driver, or a signal processing unit. Chiplets are designed to be used in a chiplet-based architecture, in which...
In order to protect technical infrastructures, systems, machines and networks against cyber threats, it is necessary to implement – and continuously maintain – a holistic, state-of-the-art IT security concept. Siemens’ products and solutions constitute one element of such a concept. For more in...
