Abstract: A parameter setting support device is provided with a parameter setting interface unit configured to display an input screen for setting a parameter of a function of a numerical controller and accept the setting of the value of the parameter of the function to be set, a related parameter identification unit configured to identify a related function related to the parameter of the settable function, based on the relationship between the parameter and each function of the numerical controller, and a setting range identification unit configured to identify a setting range of the parameter of the related function by calculating a conditional expression predetermined for the setting range of the parameter of the related function. The parameter setting interface unit displays the setting range of the parameter of the related function identified by the setting range identification unit.

Abstract: A controller managing system that enables a computer of a managing device to efficiently perform communication processing with a plurality of controllers. These controllers are connected via a network. to the monitoring computer of the managing device. The monitoring computer performs a power status determination task and a monitoring task. Each controller transmits power-ON information representing a power ON state to the monitoring computer at prescribed intervals. When the power status determination task cannot receive the power-ON information within a predetermined time period from either one of the controllers, it is determined that the power supply to that controller is OFF. The monitoring task skips the controller that is determined as being in a power OFF state; so as not to receive data therefrom, and communicates with the next controller that is in a power ON state.
