I want to ack a message without pussing on the ack button of the logo or logo TDE.

I want to this from a HMI is this also possiblle? Send an ACK on the p input of the message text blok.

The "Message text" block has no "P" input. The line of "P" is green and not black. It can't be connected to any digital or analog signal. Why it is referred to as input in the help is beyond my knowledge.

It only has one enable input. If the signal at this input is high, then the message text is active. If it is low, then the message text is inactive.
If you want to make it acknowledgeable by an HMI, you have to save the trigger event using an RS block. Then reset the RS block using the reset signal.
