Hello everyone,

I am currently working on a project involving the TM Pulse 2x24V module (6ES7138-6DB00-0BB1) to control a proportional valve. I've thoroughly read the module's manual and managed to configure the settings well. However, my understanding starts to diverge when it comes to programming and application. I am planning to use Pulse Width Modulation (PWM) to precisely control the flow rate, but I am at a loss on how to proceed with creating variables and applying the settings in TIA Portal.

Here are a few specific areas where I need guidance:

1. Examples of Functional Blocks Used: What functional blocks are recommended for implementing PWM in TIA Portal?
2. Variable Creation and Application: How should I go about creating the necessary variables and integrating them into my application?
3. Troubleshooting and Optimization: What are common issues when setting up this type of control and how can they be resolved?

I would greatly appreciate any advice, example code, or insights, especially from those who have tackled similar challenges.

Thank you in advance for your support and advice!
