Rockwell Arena仿真中‘Undefined symbol: Cold storage’顽固报错求助

模型目标 #

模拟一条生产线，实体经多道工序后进入三个冷冻隧道之一，最终通过Dispose模块流出；当5333个实体通过该Dispose模块时，仿真终止。

问题现象 #

运行仿真时，预运行检查（REPLICATE步骤）失败，报错如下：

ERROR:
A linker error was detected while processing REPLICATE
Undefined symbol : Cold storage
Possible cause: A variable or other symbol was used without first being defined.

已尝试的无效排查步骤 #

• 检查拼写：确认Dispose模块命名为Cold storage且无拼写错误
• 修复连接：删除并重新绘制三个Process模块（隧道）到Cold storage Dispose模块的图形连接
• 验证终止条件：在Run -> Setup -> Replication Parameters中确认终止条件为N(Cold storage) >= 5333且拼写正确
• 隔离测试：断开Cold storage模块及其所有连接，将前置Process模块连接到临时Dispose模块TempExit，错误仍存在，证明问题不在实体流，而是全局引用
• 彻底重命名：将Dispose模块重命名为FinalExit，同时更新终止条件为N(FinalExit) >= 5333，模型仍报原名称的错误：Undefined symbol : Cold storage

疑问 #

1. 为何重命名模块及更新终止条件后，Cold storage的“Undefined symbol”错误仍存在？
2. 此类“幽灵引用”可能隐藏在Arena模型的何处？
3. .doe文件是否已损坏？
