  • ST412 Hard Drive Interface

    ST412 Hard Drive Interface

    The ST-412 interface and its variants were the de facto industry standard for personal computer hard disks until the advent and wider adoption of the IDE or ATA interface in the early 1990s. The ST-506 and ST-412 (sometimes written ST506 and ST412) were early hard disk drives introduced by Seagate in 1980 and 1981 respectively, that later became construed as hard disk drive interfaces: the ST-506 disk interface and the ST-412 disk interface. It quickly became a de facto interface standard in the industry, although it was never formalized, or even given a formal. It used a ST-412 MFM (Modified Frequency Modulation) controller which unfortunately went to the great bit bucket some time ago. Porter the (total) worldwide shipment of all 5.

  • FC and FB interface parameters

    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.
