Hi, The error is coming from FB915. Is this a Siemens block or custom made? In case it's a Siemens block, please check out the following thread: It is possibly related to a license issue. If it is a custom made block, the block should be diagnosed. |
If I could help you, you can use the RATE button. Thank you. |

Hello Iyyapan S; W#16#A090 is an error code linked to the Modbus PN driver, indicationg a missing license key. This error code appears very often in your diagnostic buffer. How do you establish a Modbus/TCP communication from a SIMATIC S7-300/S7-400 and where can you find further information? https://support.industry.siemens.com/cs/ww/en/view/22660304 "Missing or incorrect licensing If you enter an incorrect registration key or no activation code at all, the SF-LED (for S7-300 and IM151-8) or INTF-LED (for S7-400) of the CPU flashes and a cyclic entry is made in the diagnostics buffer regarding the missing license. The error number for a missing license is W#16#A090." Please pay special attention to andress' last posts in the link provided by Oreca. Hope this helps, Daniel Chartier |
