I have encountered numerous messages when attempting to reassign an unused coil, bit, address, etc., saying that the request cannot be completed
as the memory location has been assigned. I am not certain why the software would block such a request when the nickname, coil, address, etc., is unused in the program. I would certainly appreciate being questioned as to whether or not I wish to override something previously assigned, but I find myself, as a result of testing logic sequences, being prohibited from renaming the next unassigned bit and running though multiple "not permitted" messages until I find a useful "unused" memory location. Please help me understand this time consuming and frustrating issue, as I do not always want to delete some of the test scenarios I have set up in prototyping systems.
