What is PIW in Siemens PLC?

PIW means the data from the Slave to the Master. By PCA the input data will contain the response of a parameter read or write. By Process data the first word of input data is the Status word of the FC 300 and the next is the Main Actual Value.

What does PG mean in Siemens?

programming device
Rating: (1) Your PG is your programming device (the device you use to program / interact with your PLC). In most cases that means a computer with programming software. For example, WinCC, Step 7 or TIA software (in the Siemens family).

What is OB1 in Siemens PLC?

What is SFC and SFB in Siemens?

SFC and SFB are system library code blocks that you can pull into your program just like you would any normal instruction. SFC is a system function (FC) whilst SFB is system function block. The SFB needs to be linked with a DB just like one of your own FBs will need a DB.

What are PLC blocks?

Function blocks are objects which are defined in a PLC program to simplify the process of programming. Basically, it is a means of reducing the programming length and complexity written by the programmer.

What are the different types of L P modules used in PLC?

Different types of PLC Modules

Rack or Chassis. The rack or chassis is the most important part of the modular or rack-mounted PLC system.
Power Supply (PS) Module.

What is the scan cycle of PLC?

In most PLCs, a scan cycle is the cycle in which the PLC gathers the inputs, runs your PLC program, and then updates the outputs. This will take some amount of time often measured in milliseconds or microseconds.

Why is Siemens called 27648?

Noted that 27648 is not analog maximum value, its the analog rated maximum value. The real maximum value is 32767 (overflow) -> 2^15. So if you give module’s input 10.2V it will convert into value bigger than 27648 and not destruct the module (as long as it still below permissible input voltage).
