Rules Engine - Auto On/Of mode for outputs

Hi,

A new request from a client. They have a bunch of light towers installed on multiple desk.

They want each segment of the lights to BLINK. That is turn On/Off a defined number of times by second for as long as the output is active.

We already installed the needed relays and wiring but don't know to alternate the output stated in order for the lights to blink.

Please share your thoughts,

Regards,

Miguel Dna
