Hello vorapob; The instruction is available in TIA Portal (my thanks to ixo65) as long as you have a S7-300/400 CPU and a Step 7 Professional license. Have a look at the screenshot below, built-up with content from these links: Step 7 v16 and WinCC v16 : https://support.industry.siemens.com/cs/ww/en/view/109773506/24891277323 System and Standard functions (S7-300 and S7-400) : https://support.industry.siemens.com/cs/ww/en/view/109751826 There seems to be no equivalent for S7-1200 and S7-1500 CPUs, not any longer anyway. The instruction ATTR_DB seemed to have been equivalent to SFC 24 (only for S7-1500 CPUs) until TIA Portal v14, but now it is no longer aavailable: Hope this helps, |

With a TIA Basic license he can't program an S7-300 anyway. So a professional license is required.
