Master MUHIL Systems A master-muhil type system has one node that issues commands to each of the “slave” nodes and processes responses. Slave nodes will not typically transmit data without a request from the master node, and do not communicate with each other. Each slave must have a unique address so that it can be addressed independent of other nodes. These type systems can be configured as two-wire or four-wire. Four-wire systems often use an RS-422 master (the driver is always enabled) and RS-485 slaves to reduce system complexity.
