Abstract
A PLC includes a storage configured to include a master area and a plurality of user areas corresponding to a plurality of users, a user authenticator that authenticates each user of the plurality of users, and a version controller that causes a first dataset created by the user authenticated by the user authenticator to be stored in the storage and implements version control of the first dataset. The version controller causes the first dataset to be stored in the master area or a user area of the plurality of user areas that corresponds to the user authenticated by the user authenticator, in association with a second dataset that is already stored in the storage and that serves as an immediate parent of the first dataset.
