CONTROL DEVICE, CONTROL METHOD, AND COMPUTER READABLE STORAGE PROGRAM

The invention provides a control device, a control method, and a computer readable storage program. There is expected a technique for restricting a server function without affecting a driving machinein the case where memory usage is increased. A controller includes a memory, a program execution section controlling a driving machine in accordance with a control program, and an OPC-UA server communicating with an external machine. The OPC-UA server includes: a function execution section, executing a function utilizing a memory region on the memory in response to a request from the external machine; a monitoring section monitoring usage of the memory; and a restriction section, stopping the above function of the OPC-UA server based on the fact that the usage has exceeded a predetermined threshold. A server function can be restricted without affecting a driving machine in the case where memory usage is increased. 本发明提供一种控制装置、控制方法以及计算机可读存储介质。期望一种技术，用于在存储器的使用容量变多时，限制服务器功能而不会对驱动机器造成影响。控制器具备存储器、依据控制程序来控制驱动机器的程序执行部、以及
