Good day everybody,
i have a strange phenomenon with my HA.
Hassio 6.6 64-bit runs on a Rpi3: core-2021.11.5 / supervisor-2021.10.8
My WAGO841 PLC is connected via Modbus. Currently, however, some Modbus addresses are neither written nor read - but only by the HA. If I use other tools to change the identical MB address, this also leads to a clean switch within WAGO - the status in the HA remains the same.
switches:
- name: K1
address: 12292 -> MX0.4
- name: KL1
address: 12288 -> MX0.0
- name: KL2
address: 12290 -> MX0.2
- name: BLF
address: 12295 -> MX0.7
- name: BL
address: 12296 -> MX0.8
- name: DA
address: 12298 -> MX0.10
The above is an example of the switch configuration (I wrote the MX for clarity).
- Switching between 12292 and 12288 runs without problems, nothing else happens → no status change in the Modbus monitor or in the CodeSys recognizable.
- Forced value in Codesys: no change in value is visible in the HA, but in the Modbus monitor
- Value change via Modbus app: no value change visible in the HA, but in the Codesys
So it seems that communication on some memory addresses is not working.
The joke: the identical configuration had worked for a long time. I haven’t changed anything.
Has anyone already had similar experiences or has the Modbus integration been changed but undocumented?
