Post by paho on Linux runtime mit init-functions ^{CODESYS Forge talk (Post)}
Hallo, ich habe eine Frage zu den init-functions: kann man irgendwie verhindern, dass bei einer Installation der Runtime (normal Update per CODESYS Linux Dialog) die init-functions unter /opt/codesys/scripts/init-functions immer überschrieben werden? Dort habe ich einige CPU/IRQ Anweisungen die ausgeführt werden müssen, aber nach jedem Runtime Update ist die Datei wieder auf Werkseinstellung. Danke!

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)
