Hi.

I am using PCS7 v7.1 and I have inserted a new 8P Alarm block in a picture. The alarm message is being shown correctly, but the status icon in Picture Tree is not displayed.

Must I compile the "Picture Tree" too ?

regards.

 Hi mark1507,

Yes I've placed an Alarm display (Voith Paper library  block) in a picture but when the alarm is set the red "A" is only shown in the display placed in the picture but not in the status icons of the "Picture Tree".

Need I check the checkbox "picture tree" in the OS compile window to recognize this new alarm object on the Picture Tree status icons  ?

Regards.

Hello Berg,

you need to place an object in a picture wich represents the message status of your block. This can be in e.g. a group display. Only in that case it will considered at 'calculation of group display hierarchy' wich is performed in e.g. during OS-Compilation and hence forwarded to the group display in the area overview.

Btw, I would recommend not to use the ALARM_8P in CFC. Depending on wich library you use there are other blocks for that purpose. If you use APL you could use the block 'Event' or 'EventTs'. If you use the old standard library there is the block 'MESSAGE' available. Theese kind of blocks are without a block icon, just for producing a message, so if you like that the group display (in the area overwiew) is triggered you also need to place a group display and connect it to that block. You could also make the group display invisible, anyway it will be forwarded up to the area.

But, in my opinion it is mostly better to use a block like MonDiL (APL) or DIG_MON (standard) for binary events wich should produce a message. These blocks come with an block icon and hence an operator has always the chance to follow the alarm to an specific location in the process (because you place it there). Also because those icons always comes with faceplate, it gives the possibilty to see message 'object related'...And, of course, such a block icon comes already with an group display...

If you don't like the standard block icons (what could understand very well(, you could create your own variant. That's not that difficult...

Best regards...

edit:

After reading your post again, I recognized that you obviously have placed already a group display in a picture (at least I think so because of your statement "I placed an ALARM_8P in a picture"). So for 'recalculation of the group hierarchy' you could either compile the OS or just open and save the Picture Tree Manager.

Hello Berg,

yes, I think you need to set the option 'Picture Tree' when compiling the OS, because I guess only then the picture tree will be saved during OS-Compilation. If you have a project where the picture tree is not derived from the plant hierarchy, then you could just open the editor 'Picture Tree Manager', save it and close it. Like I said, the group display hierarchy is updated (recalculated) when saving the picture tree.

Best regards...

 Hi.

I've tried this option you've mentioned: "open the Picture Tree Manager save it and close it", but the status was not shown yet  in picture tree, just in the "subfolders" (see attached file, please).

Any suggestion ?

regards.

Better late than never :)

To operate the inheritance of alarms between mnemo:
Before saving to the "Picture tree manager" make sure that the [v] "Create / Upgrade group displays" checkbox is active on the "Messagge Displays" tab in the OS Project Editor. Alternatively, this setting can be activated via the text file "..\SSM\Ssm.cfg" - the string "CreateCSIG = 1".

(Then, after saving in the "Picture tree manager", the higher-level mnemo will contain the same number of "group display" graphic elements as the lower mnemos. Each "group display" will be tied to an internal system tag that aggregates the alarms of its mnemonic scheme.)

Sorry for my level of English :)
