  The monitor run device is a device used only at the time of testing renewal, such as a CTC central device. Therefore, normally, maintenance should be performed to prevent failure and deterioration of functions while keeping them. In addition, at the time of the renewal test, the installation place of the monitor run device must be considered and secured. Furthermore, there are problems such as increased equipment purchase costs and maintenance costs.

  The monitor run device temporarily stores the display information obtained by branching from the existing CTC line inside the monitor run device, and transmits the display information to the new CTC central device in response to the display polling from the new CTC central device. Therefore, the new CTC central apparatus has a problem that the input timing of the display information from the CTC station apparatus is delayed by one cycle as compared with the existing CTC central apparatus.
