Which is format of data read in analog module of Siemens PLC?
Which is format of data read in analog module of Siemens PLC?
Each analog value (“channel”) occupies one input or output word. The format is ‘Int’, an integer. The addressing of input and output words conforms to the addressing in the device overview.
What is analog input module?
The Analog Input Module (AIM) serves as a high-density analog field sensor acquisition module. It provides for 32 independent, highly reliable, and galvanically isolated inputs with built-in filtering, A/D conversion, and calibration to be used by the Logic Module.
What’s the range of a Siemens s7-1200 analog Io?
Add your module, then configure each channel’s properties. Not that for current-based signals, the only range available is 0-20mA. If your signal is 4-20mA, still configure it as 0-20mA and scale the input value as demonstrated below.
How to write an analog output in Siemens?
Writing an analog output is a bit simpler than reading the analog input. Simply convert your analog output value to a percentage (0-100) and input that percentage into the “Scale_analog_output” library function provided by Siemens (see link above). The resulting word value can be sent directly to the analog output address.
Is there a library function for the Siemens s7-1200?
For 4-20mA input signals, Siemens supplies a library function to convert the 0-20mA to a 4-20mA range. The library functions are available on the Siemens website with instructions here: Using the Siemens 0-20mA / 4-20mA conversion blocks.
Which is OPC UA server does SIMATIC s7-1200 support?
