What are the features of Siemens S7 300 PLC?
SIMATIC S7 300 The SIMATIC S7-300 universal Controllers saves on installation space and features a modular design. A wide range of modules can be used to expand the system centrally or to create decentralized structures according to the task at hand, and facilitates a cost-effective stock of spare parts.
How do you use the high speed counter on S7 1200?
To configure a high-speed counter, proceed as follows: 1. In the device or network view, select an S7-1200 CPU. 2. In the inspector window, go to “Properties > General > High speed counters (HSC)” and click the high-speed counter “HSC1”.
What is the use of high speed counter?
A high speed counter is a hardware based counter to capture the state of your inputs. It is used when you have inputs that are switched at such a high speed that the program cycle scan would be too slow. Some of the digital inputs can be configured for high speed and how many and which inputs depend on your hardware.
What is the maximum no of high speed counters supported by S7 1200?
With the SIMATIC S7-1200 PLC you can use up to 6 high-speed counters.
Which counter is high speed counter?
The synchronous counter is the fastest counter because all the flip flop gets clock at the same time whereas in asynchronous counter clock is given only to input flip flop and it takes some time to reach all the flip flop.
What is high speed counter module?
The High-Speed Counter I/O (CTRIO) module is designed to accept high-speed pulse-type input signals for counting or timing applications and to provide high-speed pulse-type output signals for stepper motor control, monitoring, alarm or other discrete control functions.
Which counters are high speed counters?
When did Siemens S7 come out?
The first entries in the S7 line were released in 1994, available under three performance classes: S7-200, S7-300 and S7-400. The introduction of SIMATIC S7 saw also the release of a new fieldbus standard Profibus, and the pioneer use of industrial Ethernet to facilitate communication between automation devices.
What is a PLC high speed counter?
A high-speed counter (HSC) is a functional capability within particular PLCs. HSCs count the frequency of the pulse of processes from systems with elements such as high-speed encoders.
Which counters are high-speed counters?
What is a high-speed counter on a Simatic s7-1200?
1.1 Overview The SIMATIC S7-1200 offers integrated functions such as pulse generators and high-speed counters. In most cases, high-speed counters are used in conjunction with a rotary encoder to measure motor speed or the distance or length of workpieces on a conveyor belt.
What is a high speed counter used for?
In most cases, high-speed counters are used in conjunction with a rotary encoder to measure motor speed or the distance or length of workpieces on a conveyor belt.
How does a high-speed counter measure the speed of light?
When the first light barrier (gate) is darkened, the high-speed counter measures the number of pulses. A second light barrier (capture), at a known distance from the gate light barrier, detects the speed of the pencil. The length of the pencil can be determined from the speed and time of darkening and displayed on an HMI panel.
How do I activate the high-speed counter?
In the Inspector window, under “Properties> General> High speed counters “, click on the high-speed counter “HSC1”. 3. Activate the high-speed counter in the “General” parameter group with the corresponding check box.
