Abstract
A method and apparatus for communication with a remote device 250 by a node system 200 and a SCADA system 100. The SCADA system 100 communicates with the remote device without protocals or characteristics of the remote device 250 or the communication channel 270 connecting the remote device to the node system. A display 250 may monitor the communication channel 270 and may be remotely located with respect to the node system 200. The node system 200 may schedule the input from the remote device 250 by setting an interval and duration so that the input may be transmitted.
