<div class="markdown_content"><p>Hello,</p> <p>I am having a problem downloading my application to an ifm CR1074 using CODESYS.</p> <p>When I try to download the program to the controller, I get the following errors:</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'KEYBOARD_SET_MAPPING'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'SYSCFG_SPLASH_SET_SPLASH_SCREEN_VISIBLE'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'SYSTEM_IO_BACKLIGHT_SET_CURRENT_BACKLIGHT_BLOCKING'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'SYSTEM_IO_BACKLIGHT_SET_CURRENT_BACKLIGHT'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'KEYBOARD_RESET_LEDS_BLOCKING'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'KEYBOARD_SET_LED_COLOR'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p><span>[FATAL ERROR]</span> Version mismatch at: 'SYSCFG_DEVINFO_GET_KEYBOARDS_INFO'<br/> Requested version: 2.0.0.12<br/> Implemented version: 3.4.0.0</p> <p>The controller is running an OS version that should be compatible with CODESYS 3.5 SP16, and I am using the latest available ifm/ecomatDisplay package for this OS version.</p> <p>Therefore, I do not think this is simply a CODESYS or OS compatibility issue.</p> <p>It looks like the application expects system functions with version 2.0.0.12, while the controller implements version 3.4.0.0.</p> <p>Could this be caused by an incorrect or outdated library, device description, package installation, or a mismatch between the libraries used in the project and the libraries installed on the CR1074?</p> <p>What would be the correct way to identify which component is requesting version 2.0.0.12 and how can I resolve this version mismatch?</p> <p>Thank you for your help.</p></div>
