Control circuit board, control system, and copying method

摘要

A control circuit board includes a first storage unit configured to store therein predetermined data; a connecting unit configured to be connected to another control circuit board including a second storage unit; a switching unit configured to switch between a first state and a second state, the first state being a state in which data read from the first storage unit is enabled but data read from the second storage unit is disabled, the second state being a state in which data read from the first storage unit is disabled but data read from the second storage unit is enabled; and a storage control unit configured to write or read data to or from the first storage unit in the first state, and perform a copying operation that reads the data from the second storage unit and stores the read data in the first storage unit in the second state.

1. A control circuit board comprising:
a first storage unit configured to store therein predetermined data; a connecting unit configured to be connected to another control circuit board that includes a second storage unit; a switching unit configured to switch between a first state and a second state, the first state being a state in which data read from the first storage unit is enabled but data read from the second storage unit is disabled, the second state being a state in which data read from the first storage unit is disabled but data read from the second storage unit is enabled; and a storage control unit configured to
write or read data to or from the first storage unit in the first state, andperform a copying operation that reads the data from the second storage unit and stores the read data in the first storage unit in the second state.
