A schedule was created in the ENC and imported into the ENS, but it can not be edited in the ENS
Niagara G3 all versions, ENS, ENC-520, ENC-410
The imported schedule becomes the slave of the original (master) schedule. Only the master schedule can be edited. The slave schedule can not be edited.
If the schedule is to be edited in the ENS, then the schedule must first be created in the ENS and then imported into the ENC.
