Post by vformanek on How to access files correctly in Linux ^{CODESYS Forge talk (Post)}
Hello, its still not quite clear to me how to deal with the PLCLogic directory in linux. I have the directory right here: I need to correctly access the files in this folder through CODESYSControl.cfg. Here is my CODESYSControl.cfg where on the first lines there are a few lines: [SysFile] FilePath.1=/etc/, 3S.dat PlcLogicPrefix=1 That means that if I am going to use relative paths its going to go to from the PLCLogic directory right ? For example here: Whitch paths should I use. I cant seem to successfully run any of these aproaches ...

Post by climblinne on OPC UA Method - How to wait for result? ^{CODESYS Forge talk (Post)}
Hello, I am already able to run an OPC UA method in Codesys. Now my question, how can I interact with other tasks (e.g. read an SDO from EtherCAT and return it by the function)? The OPC UA method seems to be called only once (I tried to return BOOL or UINT values). Up to now I only found to do a while loop to wait for the result of the other task. Is there a better way to do it? Is this the way OPC UA functions should be used (for "not too long" function calls) or should I use another mechanism (method: Start, event: Finish, method: getResult)? Regards

Post by jeffgamsby on Accessing ModbusTCP addresses from python ^{CODESYS Forge talk (Post)}
Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.
