A system for integrating a software programmable logic controller functions along with the human machine interface functions for plastics molding machines is disclosed. The first seal portion includes a reinforcing insert disposed therein. Since the center frames are slantingly installed and support the upper frame and the side frames, the structure of the carrier has reduced weight and enables the maintenance of sufficient rigidity. The transmitting of off-channel beacons further is at a rate higher than the beacon rate frame at which the access point of the infrastructure wireless of the particular network identifier transmits beacon frames.
