PURPOSE:To change the contents of memory freely, by setting a change while monitoring the contents of storage of an operation panel, through the provision of a switching device which freely changes over the state of a monitor room connected to the operation panel and the state of the operation panel connected to the monitor panel and terminal devices. CONSTITUTION:To an operation panel 1, a terminal device 3, a control panel 4 and a monitor panel 5 are connected via a transmission line 2. The terminal device 3 stores the contents of control of a transmission signal transmitted to the device 3 until the next transmission signal is transmitted and performs load control. The operation panel 4 has a storage section which stores the contents of control and transmission time and freely changes the contents of storage of the storage section. The monitor panel 5 only connected to the operation panel 1 between the operation panel 1 and the terminal device 2. The setting change can be made to this operation panel 1 without changing the control state of the load of the terminal device 3 and the monitor panel 5 while monitoring the contens of storage of the storage section of the operation panel 4 at the monitor panel 5. |
