SYMPTOMS

In PAC Control, using an incorrect communication handle may result in a -16 Bus error in the controller's Message Queue,  and on a hardware controller the controller may reset.

For example, a value of F:\HTE\RD150415.T0000 is missing the comm handle type, such as file or tcp. When the handle is opened, it will cause an error or reset.

WORKAROUND

Make sure all required elements are included in your comm handle value. See the PAC Control User's Guide for help.
