troubelshooting ofplc

HI,why a PLC have systemfault(SF)?

PLC is a machine

Hi abbass,

PLC is a hardware which is run driven by program. Internally to make PLC run it needs internal program which is called a "Firmware". Firmware is a basic program which the PLC hardware can execute directly. Then the firmware read the program (which is made by PLC Programmer) then execute it.

Help: How to make the siemes plc recall data over a specific tim

Hello, I am working on an S7 program for interfacing the PLC to a wind turbine. I need the PlC to get the average wind speed every 20 seconds, hence i need it to recall all data within that timeline. I have tried everything i can think of getting 10 different samples by using time pulses, trying the demultiplexer and tried the MOVE also(which keeps giving me an output different from the input). none has worked. Pls, can you tell me what logfic function can work without the noise that comes from refetching information from the analog unit. i am using an S7-1200 PLC. Thanks. Hoping to get a feedback soon
