Hi
Two questions about BACnet Schedules with PcVue
- Can a schedule without any Enumeration label or without any variable linked on its output work ? $
- Since the new property "Associated label" directly on a schedule (11.2 update 4?) is it still manadatory to have a variable linked on the schedule's output ?
Thanks

Hi Nico,
- Can a schedule without any Enumeration label or without any variable linked on its output work ?
It depends what you mean by work. A schedule object without any output has no-sense as the only action a schedule object is doing is to set his output...
- Since the new property "Associated label" directly on a schedule (11.2 update 4?) is it still mandatory to have a variable linked on the schedule's output ?
Yes

Hi,
What I have also understood about the first question is:
Can a schedule without any Enumeration label but with a linked output work ?
I guess the answer is yes but by default the set value is 0 or 1. Isn't it?

After test
With the new property "Associated label" directly on a schedule you dont't have to link any PCVUE variable on the schedule's output to be able to play with your schedule on WebScheduler.
Nico K : "A schedule object without any output has no-sense"

yes, you can manipulate the schedule object if no output has been configured.
But, I am not sure it's a good idea because, as said by Edouard, the default output is 0/1
Now imagine the scenario:
- You create intervals with 0/1
- Later, you affect the output with a register linked with an Enum Associated Label.
- Conflict...

Hello,
The default value is configured in the "Schedule-Default" property of the schedule object. It could be a boolean, long, int, enumt, double, ...
for information, the default format used by PcVue is an enumeration.
If the property "list of object property references" (named schedule output) is not configured in the device, you can set the associated label (enum or bit label) directly on the schedule.
I don't know how it is configured in the device but maybe there is a possibility to "hide" this property to a BACnet client.
I saw that behavior in Siemens devices.
By the way, it makes sense to only have the access to the time table and not the value to set.
In the WebScheduler, if don't configure associated label, you can't create a new time table, so you are limited.
Hope it helps

Thanks Brice for the details.
Just one point about this
If the property "list of object property references" (named schedule output) is not configured in the device, you can set the associated label (enum or bit label) directly on the schedule.
I assume you wanted to say "....you can set the associated label (enum or bit label) directly on the PcVue schedule object".
I just indicate this for those that don't know this BACNet part in detail as the Schedule object (in the device) has no "Associated label" property.
