我在编程的完成编译的时候报这个错误“Network 1, line 8, ERROR 18: (operand 1) V-Memory not allocated for library. Select right mouse menu item 'Library Memory...' from the Program Block in the instruction tree
Block Size = 0 (bytes), 119 errors”用到了“MBUS_MSG,MBUS_MSG_P1,MBUS_CTRL,MBUS_CTRL_P1” 请问这个是什么错误?怎么处理?谢谢
专家建议
雏狼您好:
您的错误在于需要给modbus 库指令分配库存储区。
