Why is there no 'Show ISY PLM Links" option?

So we can see what the ISY thinks the link tables of a device should be. Why is that option not available for the PLM? It would be nice to get a quick count on total number of links in the PLM.

 

Under Tools>Diagnostics>Show ISY Links Table there is as drop down menu where you get to pick the device that you wish to view the links ISY thinks the device should have. Why is the PLM not one of the devices available to choose in this list?

The ISY manages link records by location in individual devices. That is, the ISY knows what link record is at each link record address in the individual device. This information allows the Show ISY Links Table for a device to display the link records as they should appear in the device. It also supports the Compare function for individual devices.

 

Link Management in the PLM is very different. The ISY does not manage link records in the PLM by address. The PLM is given a command to add or delete a link record. No link record address is provided. The PLM has logic to locate the link record for a delete and find an available slot for an add. The ISY has no information about where any given link record is located so has no information to produce a display for a Show ISY PLM Links Table.

 

The Show PLM Links Table reads the PLM link database sequentially. There is no Compare function for the PLM for the same reason. The ISY has no information as to what link record should be where for a PLM.

As always, thanks LeeG.

 

A very thorough and informative answer.
