Programmable terminal system

A management method for a programmable terminal system including at least a programmable terminal device and a server device connected through a network, the management method comprising:

• providing a nonvolatile memory and a volatile memory in the programmable terminal device and a nonvolatile memory in the server device;
• separating multiple confidential content screens for display on the programmable terminal device into confidential data for displaying a confidential content part and non-confidential data for displaying a remaining part;
• storing the non-confidential data in the nonvolatile memory of the programmable terminal device and the confidential data in the nonvolatile memory of the server device;
• storing, in the nonvolatile memory of the programmable terminal device, storage location data indicating a storage location of the confidential data in the server device;
• acquiring by downloading the confidential data based on the storage location data and storing the confidential data in the volatile memory of the programmable terminal device when the screen including the confidential content is requested;
• and
• displaying the screen based on the non-confidential data stored in the nonvolatile memory of the programmable terminal device and the confidential data stored in the volatile memory of the programmable terminal device.

A programmable terminal device including a display panel for displaying information and having a function of receiving content data distributed from a server device through a network, the programmable terminal device comprising:

• a nonvolatile memory for storing a screen data file for each available screen, wherein the screen data file includes part configuration information for each screen part, wherein the part configuration information is categorized into a first group including content data acquired from a server device and storage location information of the content data and a second group not including the content data;
• a volatile memory;
• a communication circuit connected to the network for communicating with the server device;
• a display screen determining part for determining a corresponding screen to be displayed;
• and
• a screen display control part for displaying the corresponding screen on the display panel based on the screen data file stored in the nonvolatile memory, wherein the screen display control part comprises a first display control part and a second display control part,
• the first display control part for controlling display if the part configuration information read from the screen data file is in the second group by displaying the part configuration information included in the screen data file in the nonvolatile memory,
• and the second display control part for controlling display if the part configuration information from the screen data file is in the first group, the second display control part causing a transmission request command including storage location information of the content data in the server device to be transmitted to the server device through the communication circuit, wherein responsive content data arriving with a response from the server device is stored in the volatile memory and the part is displayed using the content data stored in the volatile memory and the part configuration information in the screen data file of the nonvolatile memory.

A server device that distributes content data to at least one programmable terminal device through a network, the server device comprising:

• a nonvolatile memory storing content data to be downloaded to the programmable terminal device;
• a communication circuit connected to the network for communicating with the programmable terminal device;
• a content data search part for searching the nonvolatile memory for requested content data based on storage location information included in a transmission request command from the programmable terminal device;
• and
• a response transmission part for transmitting a search result obtained with the content data search part to the programmable terminal device together with a response to the transmission request command through the communication circuit.

A programmable terminal system including at least a programmable terminal device having a display panel and a server device connected with the programmable terminal device over a network, the system comprising:

• a nonvolatile memory within the programmable terminal device for storing a screen data file defining a configuration for each available screen using part configuration information, the part configuration information divided into two groups, a first group including content acquired from the server device and including storage location information of content data in the server device and a second group corresponding to the part not including the content;
• a volatile memory within the programmable terminal device;
• a screen display processing unit within the programmable terminal device, the screen display processing unit comprising a display screen determination part for determining a corresponding screen to be displayed and a screen display control part for displaying the corresponding screen on the display panel based on the screen data file stored in the nonvolatile memory of the programmable terminal device, the screen display control part comprising;
• a first display control part for controlling display of part configuration information in the second group by using the part configuration information included in the screen data file in the nonvolatile memory, and
• a second display control part for controlling display of part configuration information in the first group, wherein the second display control part sends a transmission request command through a communication circuit to the server device, the transmission request command including storage location information of the content data in the server device and wherein the second display control part receives a response from the server device including content data for storage in the volatile memory such that the requested part is displayed using the content data in the volatile memory and the part configuration information in the screen data file of the nonvolatile memory;
• a nonvolatile memory within the server device for storing the content data to be downloaded to the programmable terminal device;
• a content data search part for searching the nonvolatile memory of the server device for the corresponding content based on the storage location information included in the transmission request command;
• and
• a response transmission part for transmitting a search result from the content data search part to the programmable terminal device together with the response to the transmission request command.
