How many Input and outputs s7 200 plc have?
s7-200 have 14 inputs and 10 outputs that can be relay or transistors. Check out www tmartis com for affordable plc and modules.
What is the difference between PLC and embedded systems?
An embedded system is typically made to do one set of task or similar sets of tasks. An internet router uses an embedded system and so does an MP3 player. There are usually some options as to how the task are carried out, such as choosing to set a password for your router or choose a song on the MP3 player. PLC's on the other hand, operate using IF-THEN instructions. If the water gets too high, THEN open the valve to release some. IF the water gets too low, THEN turn on the pump. A PLC can be used to operate a whole process, like brewing beer or refining fuel. Most PLC's connect to many different types of sensors for inputs. Some examples of these sensors are: flow, pressure, temperature, and level, but there are many more. Outputs usually are connected to relays to control power to electrical devices that require more current than the PLC can put out. A PLC may also interface with an embedded system. There are some cases where either will do. One commonly used appliance that would work with either is an automatic coffee maker. Also, clothes washing machines used to use simple PLC's while many of the new ones use embedded systems.
What makes PLC communicate with SCADA?
There are different communication protocols between PLC and the SCADA. Popular SCADA being PC based, most used communication protocol is ethernet/IP. The PLC tags are used to build the objects in SCADA so that Actions or states or status or parameters of PLC are displayed on SCADA.

I am facing the temperature dissimilatory issue, installed PLC is S7300, there is lot of sensors (thermocouple and RTDs) are installed. even replaced the sensors and plc analog modules with new with front connectors?
so they can learn

What do you mean by PLC in Machine?
It stands for Programmable Logic Controller. It is the brains of the machine. It takes inputs whether manual or automatic and outputs signals for operation.
What applications would you use a unitary plc?
unitary PLC's are used in standalone systems as the have limited inputs and outputs, theses are mainly used in small scale engineering companies in operations such as control operations, component counting and sorting.
What are the uses of plc's?
PLC stands for Programmable Logic Controller. It is a computer that controls/automates industrial machinery and equipment by monitoring inputs, and controlling outputs based on what the program running on the PLC tells it to do. Examples of inputs: tachometers, switches, thermostats, etc. Examples of outputs: lights, horns, high voltage contacts for switching motors on and off, etc. PLC's are used to control amusement park rides, conveyor systems, and most industrial equipment found at production lines, mills, etc. A PLC can be used to control/automate virtually any piece of equipment or machine.
How do you program the plc?
A PLC programm is basically a correlation between inputs and outputs, you can program this in one or a combination of the following languages: Ladder logic Statement list Function blocks However to communicate with the PLC you'll need an specific software provided by the manufacturer i.e. Step 7 for Siemens or RSLogix for AB
What is the standard wire color for PLC inputs and outputs?
There is no specific standard for PLC inputs or outputs, as existing standards wire color codes are based on voltage rather than by function. Different standards apply in the USA, Europe or other countries, and it depends if you intend to wire a PLC for a domestic application or it is going to another place where the requirements may be different to the local ones. Check it. These standards my help you: NFPA 79 UL 508A IEC 204.1 / EN 60204-1 If you mention where you are located or where is that piece of equipment going, maybe I can give you further info.
What is the Function of the CPU in plc?
1_ Updating the inputs and outputs. 2_ Perform logic and arithmetic operations. 3_ Communication with the memory. 4_ Scanning application programs. 5_ Communicating with a programming terminal.
Does a PLC have timing control?
When choosing a PLC for an application you have to look at the specifications of the model. There are a wide variety of specifications under one model type. Some have built in timers others don't. I/O inputs and outputs can operate on different voltages. Make a list of the operations that you would like the PLC to do and call the sales representative of the PLC company that you choose. They are very good at what they do and they will tell you which of their units will be able to fulfill the actions that you want the PLC to control.
What is the difference between the DN and EN outputs of a timer or counter in a PLC?
PLC differences between timer and counter
Explain the Input and output limitation of the PLC?
With a PLC the I/O is fixed when you buy it. Smaller stand alone units are hardwired with the exact I/O you are going to have. Even expandable configurations have a fixed input and output memory table. The PLC scans its Boolean algebra logic, constantly and sequentially, and compares that program to the I/O tables' inputs, outputs and relays. Then it makes its' decisions depending on their state.
Is input on plc normal close or normal open?
PLC can take both types of inputs. Logic can be written suitably with in the processor software.
Inputs and outputs of robotics?
An input is when something receives a signal to do something, and an output is sending out a signal. This is usually used in PLC's, or Programmable Logic Control, where an input,(a signal you send to the system) triggers an output, which in return triggers something, like a motor to move.
