Controlling Analog Output with Up/Down Arrows on LOGO! 8 HMI

Dear Maurizio,

Here's how to configure up/down arrows on a LOGO! 8 HMI (6ED1055-1MM00-0BA2) to increase/decrease an analog output value. You'll need to combine HMI configuration with LOGO! 8 programming.

Steps:

1. LOGO! 8 Programming: Create analog output block (e.g., QA0). Create network with increment/decrement logic. Use memory bits (e.g., M1, M2) as signals for increment/decrement.
2. HMI Configuration (LOGO!Soft Comfort 8): Create up/down arrow buttons.
3. HMI - LOGO! Communication: Map arrow button events (press/release) to LOGO! memory bits (M1 for Up, M2 for Down).
4. HMI - Display & Control: Create an Input field to display the analog output value.
5. HMI – Value Adjustment: Link the Up/Down arrows to change the value in the Input field and then write to the LOGO! analog output block.

Example Resources:

• Siemens Support Forum: Siemens Industry Forum (Search for "LOGO! HMI Analog Control")
• LOGO! 8 Documentation: Refer to the LOGO! 8 manual for details on analog outputs and networking. LOGO! 8 Manual
• HMI Configuration Guide: Explore the LOGO!Soft Comfort 8 help files for HMI element configuration.

For a complete example project, search the Siemens Support website using keywords like "LOGO! 8 HMI analog output example" or "LOGO! HMI value adjustment".
