libplctag: Downloading to PLC breaks tags

Hello Kyle. I have noticed with Micrologix PLC’s that sometimes when you download to the PLC or go live with it, it breaks all of the library’s tag connections. I cannot auto-recover from this state (close all tags and re-create) until the program is restarted. How can I resolve this issue without restarting the code?

When I try to do a read on a tag (i.e. protocol=ab_eip&gateway=10.0.0.3&path=1&cpu=mlgx&elem_size=4&elem_count=1&name=myFloatArray) I get this error: PLCTAG_ERR_REMOTE_ERR after a new program has been downloaded to it.

Thank you.
