Difference Between Functions Function-
FC and FB interface parameters
Function Blocks (FB) and Functions (FC) have three different interface types: FBs and FCs receive parameters through the IN and IN/OUT interface types. What should you watch out for in STEP 7 (TIA Portal) when transferring FC and FB parameters for new S7-1200 / S7-1500 controllers? The following description applies to S7-1200 (FW V4. 0 and higher) and S7-1500 firmware. Once you take a new FB, it will ask you to create a new instance DB or data block. Use function blocks for everything else. Temp variables defined in the FC are stored in the local data stack, which will be lost after the execution of FC. This means that the function block may not return the same output values, if it is called repeatedly with the same input.

The function of the grounding wire on the network patch panel is
grounded cabling system carries noise currents induced by electromagnetic interference (EMI) in the environment to ground along the screen or foil shield, thereby protecting the data-carrying conductors from external noise. The screen or foil shield also minimizes cabling emissions. A patch panel is a hardware device used to organize and manage network cable connections, helping to keep network wiring neat and efficient. Based on the shielding type, Cat6 copper patch panels are categorized into two types: shielded and unshielded. Cat6 shielded patch panels include an. Choose an unshielded patch panel when your environment is “normal” (office, IDF/MDF, clean data hall), your cable routes are sane, and you want fast installs with fewer grounding variables. Grounding is done on one end only - at the patch panel.
