I’m working on connecting an EA9-RHMI to my S7-1200 PLC. I have been following this guide: The HMI is giving me a 0x8104 error. I've looked online regarding this error and found this: "Function not supported, or with S7-1200/1500 “Permit access with PUT/GET communication from remote partner” needs to be enabled." However the 'Permit PUT/GET...' box is definitely checked in TIA portal. I have attached a picture with some additional information. Any ideas on other things to try or check? |

Ok, questions: S7-1200 firmware revision? After that, search this support site, and the TIA Portal / WinCC conferences for topics related to HMI connection problems. I feel like you will find your solution faster that way than waiting until someone answers you Monday after returning to their work area and checking these forums.

Firmware V4.5 No this HMI cannot connect to Optimized DBs. However my test HMI program is only looking at one tag in a DB and I made sure that one was non-optimized. I have also followed this guide for addressing and config: |

The security configuration may need to be updated to allow HMI access. Check TIA Portal help on configuring the security settings to allow HMI access without user/pass combo being required. I assume the error code means the HMI is in the same subnet as the PLC, but the requested DB #, and byte / size is being denied by the PLC. If you are online with the PLC in TIA Portal, and check the PLC diagnostics buffer, are there any entries that give you any hints? What DB #, and address / offset in the DB are you requesting? Hopefully DB1, byte's 0 and 1.
