text: <s>[INST] PF 755 Device Logix communication Summary: Error when trying to connect to device logix in drv explorer. We are currently commissioning a network of 8 PF 755 drives. We have had no issues over the development and testing until this point. We are now unable to access device logix on 7 of the drives using drive explorer. We are also unable to download to the drive using controllogix 5000. The error that shows up when downloading with controllogix is links may be locked, preventing a download. [/INST] Are you running a CIP Motion connection to these drives as well as the DeviceLogix program ? You can't run both at the same time. Is there an error code accompanying the error message ? Sometimes the precise code, like E12345-6789 can help. \\n </s>
