Hi, I’m looking for some help in setting up an interaction between a component in Perspective (an on/off toggle) and a Gateway Timer Script. The script is setup to generate a series of tasks (DB insert operations basically) every hour and I’d like that script to be something that can be turned on or off by a user using the toggle. Can this be done? ---

So you want it so your gateway timer script only runs if and only if that toggle button is in the “on” position essentially? I would make a Gateway Memory tag thats a bool or int, lets call it `enable_timer_script`, and in your perspective project, the value of your button is bound to this tag/writes to it. So if your button is on, the tag = 1 or True (depending on what type you used). Then, in your gateway timer script, I would start off the entire thing with ```auto if system.tag.value("enable_timer_script").value: # Do rest of script ``` Unless I am misinterpreting what you are asking for. ---

That’s exactly what I’m looking to do. Thanks so much! I’ll that out. ---

A small note: > [@bkarabinchak.psi](#): > > ```python > if system.tag.value("enable_timer_script").value: > # Do rest of script > > ``` This should be ```python if system.tag.readBlocking(['path to enable_timer_script'])[0].value: ``` ---

Can you explain why in this instance? I thought `readBlocking` was only necessary if you had a list of tags you needed to get at the same time? Since this is only one tag, I thought `system.tag.read().value` would work here. Also, I meant `system.tag.read("enable_timer_script").value`, not `system.tag.value("enable_timer_script").value` ---

system.tag.read is technically deprecated ---

I was mainly meaning that system.tag.value didn’t exist. However, as @bschroeder said, system.tag.read has been deprecated, so any new scripts should use the appropriate functions for the case. `system.tag.readBlocking(), system.tag.readAsync(), system.tag.writeBlocking(), system.tag.writeAsync()` ---

One more question actually: Can new system tags be freely created? ‘Create new tag’ options are grayed out when using the System tag provider for me. If not, I’m wondering if a Project scoped tag would work just as well even though it’s a Gateway script. that’ll be referencing the tag. This should be the only project running on the Gateway so I don’t see a conflict there. ---

So tags are gateway scoped not project scoped (Except for Vision Client tags). System tags are pre-defined tags that the gateway creates, not tags that are available across the entire system. Each tag, except for Vision Client Tags, is available across all projects on the gateway.
