In J-PARC control System, machinery having a network controller(NTC) is operated with EPICS. A NTC can also connect with an upper level computer directly, while in EPICS, an IOC is used for communication between an upper level computer and a NTC. In case of a communication error, one must investigate the source of the error, whether it is due to the NTC. It becomes very effective if one can switch the connection method between EPICS and direct connection on an operation screen. We report on a development of a tool realizing such functionalities.
