    • A programmable logic controller includes a device that stores therein data, an authentication-information storage unit that stores therein authentication information, an authentication function unit that performs a user authentication based on the authentication information, and an encryption filter that has a plurality of encryption patterns. When writing of data to the device is requested, the authentication function unit performs the user authentication. When the user authentication is successful, the encryption filter performs the encryption processing to the data with the encryption pattern set in advance by the user to write the data to the device, and when the user authentication fails, the encryption filter performs the encryption processing to the data with one of the encryption patterns that is different from the encryption pattern set in advance by the user to write the data to the device.
    • 可编程逻辑控制器包括存储数据的设备,存储认证信息的认证信息存储单元,基于认证信息执行用户认证的认证功能单元和具有多个加密模式的加密过滤器 。 当请求向设备写入数据时,认证功能单元执行用户认证。 当用户认证成功时,加密过滤器对用户预先设置的加密模式对数据进行加密处理,将数据写入设备,当用户认证失败时,加密过滤器执行加密处理 该数据具有与用户预先设置以将数据写入设备的加密模式不同的加密模式之一。
