Sting to BOOL and vice versa not working on raspberry PI [message #1834277]

I have modified blinking program to use String to BOOL FB and BOOL to string FB between publish and subsribe FBs. I found this is working good when deployed on two PCs. but when i use one PC and other part of the program on raspberry PI i am getting "Datatype error" on subsribe FB. Please check the attachments. I want to use this conversion because finally i want to use MQTT for data transmission between PC and raspberry PI which takes on srings as the input and outputs only strings.
index.php/fa/39218/0/

If i do it vice versa then program works till BOOL to String FB but thereafter it does not transfer data.

Can you please check the deployment console for any deployment errors. It looks like that the green part of your applciation or at least the F_STRING_BOOL was not deployed to your raspberryPY.

The crictical error message is: UNSUPPORTED_TYPE

this means that you the F_STRING_TO_BOOL FB tpye is not availble in the 4diac FORTE version runing on your raspi. you need to add the iec 61131-3 module where this fb is contained in.

Thankyou Alois. Yes... I checked FORTE_MODULE_IEC61131 in CMake tool and rebuild the FORTE for raspberry PI and it is working!
