Lower-cost memory enables a tag-name-based system.Tag names take up more memory than typical fixed address PLC systems,so they require more total memory to achieve the same application functionality.Greater memory also allows vendors to store program files on the controller.This is a huge convenience for troubleshooting in the field,and it also solves a common problem of losing the tagname interpreter files when these files are not saved in the controller.

For some PLCs and PACs,the task manager has a similar impression and method of managing programs.Program organization is an ideal tool for large projects that span multiple equipment/processes

成本更低的内存，使得基于标签名的系统成为可能。与典型的固定地址PLC系统相比，标签名会占用更多的内存，因此要实现同样的应用功能，它们就需要更多的总内存。更大的内存，还可以允许供应商将程序文件存储在控制器上。这对于现场的故障诊断来讲，是个巨大的便利，而且还解决了一个常见问题：当这些文件没有保存在控制器中时，容易丢失标签名解释器文件。

对于某些PLC和PAC来讲，任务管理器给人的印象以及管理程序的方法都比较类似。对于范围涵盖多个设备/工艺过程的大型项目来讲，程序组织功能是理想的工具
