It says your SM1281 firmware update is incomplete (or not presenting the expected signature). According to the online documentation, V14 SP1 includes native support for ES04, so the HSP is not required. For ES03 (firmware v2), the HSP is required. I would enable the web server, and use it to update the SM1281 firmware located here: https://support.industry.siemens.com/cs/document/109755629 Use the online / diagnostics for the SM1281 to see what it shows for device diagnostics. In your project tree, right click on the module and select online/diagnostics. Then look at each option top to bottom in the upper section. The lower section may not apply to this problem. Before you get too far along, I would also strongly urge you to contact Siemens support, create a support request, and send Siemens your project (as an archive). After you send the support request, update the firmware. After that, if it were me, I would boldy power the PLC completely off for a good 15 seconds. If the SM1281 uses 24V power, also turn off 24V to the SM1281. If your SM1281 uses 24V power and your 24V supply comes on after the AC powers the PLC, that may be a problem. You will want to ensure the 24V supply is on before applying the AC power to the PLC. Perhaps a 24V powered relay from the same branch circuit that powers the SM1281 that then applies power to the PLC would work for troubleshooting purposes. When I have a 24V supply, I tend to also use a 24V PLC to avoid these kinds of potential complications. |

Thank you huggy_d1 for your quick response. Sadly, I have no idea how to enable the web server of the SM1281. Since the very first beginning, I couldn't make any program which I could use successfully with the SM1281 because of the exposed error, though no idea if I configured the IP or any further network configuration. When I use de online diagnostic, the module has no problems. Only the PLC has the issue. Attached is an image with the messages from TIA portal. I have already contacted Siemens support but your answer is the best one for now. Btw, I had no idea about the power supply issue. I will definitely take it in count. greetings Diego Sandoval |

The way updates happen on the s7-1200's is the web server on the PLC once enabled can send updates to any hardware physically connected to it. For the SM1281, that front slide buss connector is that connection which allows firmware updates to go into the web server for the PLC, and over to the SM1281. Try it. When you enable the web server for the PLC, you will have to restart the plc after downloading the hardware configuration update.

Section 14.2 of this manual https://cache.industry.siemens.com/dl/files/490/109481490/att_885698/v1/cms1200_sm1281_operating_manual_en-US_en-US.pdf has this key piece of useful information!!!
