Abstract
Abstract A monitor and control apparatus according to the present disclosure includes a configuration and environment monitor (CEM) connected to a plurality of remote station monitors of a computer system for executing commands at the remote stations and for monitoring abnormal conditions thereat. The remote monitors each include a Johnson counter responsive to clock signals from the CEM to sequentially step through its output positions. Address means is selectively connected to first output positions of the Johnson counter to provide a unique address for each remote monitor. Monitor means receives monitor condition signals and is arranged with a transmitter to transmit a signal to the CEM upon sensing a fault. The CEM then sequences the Johnson counters to cause the address and fault identification data in the operated monitor to be transmitted to the CEM. Control means is provided to perform selected control operations at the remote station, the control means being connected to second output positions of the Johnson counter. Selective means is responsive to address signals from the CEM on a select channel to disable all control means in remote stations whose address is other than that received. Control signals on the select channel then operates the selected command in the addressed monitor.
