<p>PURPOSE:To early detect the abnormality of a numerical controller, etc., by monitoring the numerical controller, etc., at each fixed time and performing the communication of data via a cell controller. CONSTITUTION:A cell controller 10 carries out both the monitor and communication modes of a numerical controller 20, etc., at each fixed time. That is, the controller 10 nomitors the numerical controllers CNC 20 and 30, a robot controller 40, and a programmable controller PC 50 respectively at each fixed time in a first monitor mode 1. Then the controller 10 uses the remaining time as a communication mode 2. Both modes 1 and 2 are repeated and then a monitor mode 3, a communication mode 4, a monitor mode 5, and a communication mode 6 are carried on respectively. Thus the monitor and the communication are carried out for the controller 20, etc., with division of data. As a result, the abnormality of the controller 20, etc., can immediately detected.</p> |
