When the rung goes “true” all rungs are scanned according to their normal rung conditions. When the rung goes “false” all non-retentive outputs within the controlled zone are disabled. Two MCR instruction are used to perform the function, One is to start the MCR zone with input condition as must and another one is to end the limit area.Īn input condition like Emergency switch is programmed on the rung of the first MCR to control rung logic continuity. Using this instruction, we can disable all the outputs at the same when MCR condition goes off. The MCR zone ends with the rung that has the second MCR instruction only. It begins with the rung that has the first MCR instruction. The zone being controlled is known as the MCR zone control.
