Hi

We want to monitor OPC tag data in Subscriptions and when the tag data changes, we want to trigger the manufacturing process.

We have set up a Trigger Condition and rewritten the OPC tag so that the condition is ture.

However, the manufacturing process is not triggered.

Please let me know if there is any possible reason for this.

■Subscriptions Settings

■OPC Data

Hello Kimihiko,

An Agent Instance should be automatically created in PCo once a Subscription is successfully deployed, so you don't need to create it manually.

Hello Kimihiko,

Your setup looks fine. See below a couple comments from my side:

- You have to make sure the condition becomes False, before becoming True. So for example, if the tag value was already 901 and you changed to 902, both are bigger than 900 and the condition was always true. In this case, you must set it to less then 900 before setting it bigger then 900 again to trigger the condition.

- Is your Automatic Trigger > Subscription successfully deployed to PCo and currently Active/Current/Running?

- Check Configure Production Connectivity app to see if your PCo is connected and your Agent Instances inside your Shop Floor System are Started.

- Check PCo logs in directly in PCo itself or in DM at your Shop Floor System within Configure Production Connectivity app to find any errors.

- Double check Monitor Production Processes app to see if your PPD is being called and if there are any errors.

Hope it helps,

Manoel

Hi, Manoel

Thanks for replying!

In what you taught me, I have not created an Agent Instance.

I will try to create an Agent Instance.

I thought the Agent Instance setting was not mandatory.

I thought I could do the following 1. 2. and control the data in the manufacturing process for the OPC content.

1. Integrate OPC with PCo's Source System

2.Integrate with PCo and DM
