Link mater device求解！

A Link Master device controls when devices access the fieldbus and executes the link schedule which synchronizes communications with function block execution on the fieldbus.

The H1 card or any field device that supports Link Master functionality can function as a Link Master device.

Only one Link Master device can be active at a time on the fieldbus segment. This device is called the LAS.

The DeltaV system can configure one Link Master device to function as the primary Link Master device.

When the primary Link Master device is attached to the fieldbus, it takes over as the LAS.

The H1 card always functions as the primary Link Master.

When the H1 card is redundant, the secondary H1 functions as the primary Link Master if the primary H1 card fails.

All other Link Master devices are backup Link Master devices that can take over as LAS only if the primary Link Master device fails.

One backup Link Master field device is supported per fieldbus segment. The fieldbus devices communicate on a schedule (executed by the LAS) as required to implement the control strategy.

非常感谢您！另外这个在组态的过程中需要主动去设置吗？还是DeltaV默认H1卡就是primary link master同时 ...

Link Master:controls when devices access the fieldbus and executes the link schedule which synchronizes communications with function block execution on the fieldbus.Link Master devices are capable of taking over as LAS if the Primary Link Master device fails.
The backup Link Master must use address 20.

thank you very much! would you like sends me your weixin count ?

有Delta V问题来这里，基本、应该能解决吧。这里也有好多Delta V的资料，你可以去资料区看看。
