Solved the issue, (apparently) I unchecked the GET PUT bit, downloaded the configuration and then checked the GET PUT bit again, then it started working. Thank you.

Yes, I am certain that it was fully working before, We are trying to use the PLC TAGs because we are reading the inputs from an I/O card wich have addreses such as (%I0.0). And it made sense to have all the variables gruped in the same place. We are using the read_area with differents Areas acording to the memory type (0x81 to read inputs (%I)), (0x82 to read outputs %Q) and (0x83 for directions that are %M)

This was properly configured when we were having the problem. However, We are not using a DB for the Tags that need to be read or write, we are using the PLC tag s table. So, they have a fixed memory addresses and we are accesing them from the snap 7 referencing them as DB0.

We have an application with a Raspberry pi using SNAP7 and a S7-1214. The application was workin smoothly but the PLC was programmed in TIA PORTAL V13.0 (wich is not compatible with new versions of TIA PORTAL). So we have proceed to update this using the following steps: 1-We've created a new proyect with the PLC in TIA PORTAL V13 and uploaded the software from the PLC 2- Upload the TIA PORTAL from V13 to V13 SP2 and then to V16. 3-We reseted the PLC to factory settings and downloaded the software...
