Hi ,I'm new to plc programming I have old controllogix plc with 1756-l55M12 controller I downloaded trial version of rslogix 5000 v16 I was able to see all the modules via rslogix 5000 and rslinks but it was not able to go online with the controller because of the firmware version was 10.28 , then I upgrade the firmware to 16.23 which is supposed to be compatible version with the controller now it can go online and it's able to download and upload but I'm not able to add new module or to create any routine, I need help to solve this issue
