Programmable display device, and control system

A programmable display device that is connected to control devices that store setting information for performing a predetermined control process and perform the control process based on the setting information, and performs a backup or restore process of the setting information, the programmable display device comprising:

• a communication process unit that accesses the control devices;
• a file system process unit that accesses a storage medium that stores therein first information including target control device information and target setting information and is built in or detachable from the programmable display device, the target control device information specifying a control device that is to be a target for the backup or restore process out of the control devices connected to the programmable display device, the target setting information specifying setting information that is to be a target for the backup or restore process out of a plurality of pieces of setting information stored in the control device specified in the target control device information;
• and
• a setting information obtaining/writing process unit that accesses the control device via the communication process unit based on the first information in the storage medium in accordance with a request for performing the backup or restore process from outside, and performs the backup or restore process of the setting information by accessing the storage medium via the file system process unit.

A control system that performs a backup or restore process of setting information of a control device, the control system comprising:

• control devices that store therein setting information for performing a predetermined control process and perform the control process based on the setting information;
• a programmable display device that is connected to the control devices and displays a state of the control devices and a display screen including a setting screen for the control devices;
• and
• a storage medium that is built in or detachable from the programmable display device, wherein
• the storage medium stores therein first information including target control device information and target setting information, the target control device information specifying a control device that is to be a target for the backup or restore process out of the control devices connected to the programmable display device, the target setting information specifying setting information that is to be a target for the backup or restore process out of a plurality of pieces of setting information stored in the control device specified in the target control device information, and
• the programmable display device includes
• a communication process unit that accesses the control device;
• a file system process unit that accesses the storage medium;
• and
• a setting information obtaining/writing process unit that accesses the control device via the communication process unit based on the first information in the storage medium in accordance with a request for performing the backup or restore process from outside, and performs the backup or restore process of the setting information by accessing the storage medium via the file system process unit.
