从官网下载的v15.1库，使用时发现无法下载到仿真器，查手册说是要勾上项目和块的“ "Support simulation during block compilation"  但是项目的那个勾可以勾上，功能块的不能勾上。下面时下载时提示的错误：

'LGF_PulseRelay_1 [FB9]' cannot be simulated. If the block is a library block, use a library with simulation support. Otherwise, select the option "Support simulation during block compilation" in the project properties and recompile the block.,

请问哪位大神遇到并能解决 谢谢啦！
