The Error messages that Eclipse has Setups or Tools Locked are normal under some conditions. For Example, Setups cannot be modified while Eclipse is uploading or updating setups. The same goes for Tools or any of the record chains in memory.

However, MODBUS, when the PLC Remote Setup or Tool Configuration Selection features are enabled was causing this condition to be much more likely. The MODBUS code was reading the current configuration ID's from the PLC and should have been looking for a change before making a selection. Since it did not look for a change, every manual shear(for example) would cause the Setup and or Tool Configuration to be re-selected. If an operator tried to clear the queue with two manual shears in a row, depending on how quick Eclipse was, Setups and or Tools may have been locked and the operator would get a message indicating such on the second shear attempt.

This has now been resolved by only attempting to update the Setups and Tools when the PLC has actually changed its selection to be different from the current Setup or Tool configuration.
