Upgrade plan:Smaller industrial processes can accommodate PLC systems,but if the process needs to be expanded or upgraded,more PLC hardware and databases will need to be added,and separate maintenance will be required.This is a time-consuming,labor-intensive process and prone to errors.The DCS system is easier to upgrade,for example,the user trust can be managed from a central hub,so it is easier to maintain and maintain

升级计划：规模较小的工业过程可以适用PLC系统，但如果该过程需要扩展或升级，则需要增加更多的PLC硬件和数据库，并且需要进行单独维护。这是一个耗时、费力的过程，而且容易出现错误。DCS系统更容易升级，比如可以从中央集线器对用户受信进行管理，因此就更易于保养和维护
