I am using an E1212 to simulate pulses from a power meter (E1212 DO drives SSR). Can the ON width and OFF width, as pictured, be **written to** via ModBUS TCP? @pturmel @Chris_Taylor ![moxa DO](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/a/1ad6353636702bbff85554165bba62fdf402dc9e.png) ---

Here is the series manual: [https://www.moxa.com/Moxa/media/PDIM/S100000327/moxa-iologik-e1200-series-manual-v15.2.pdf](https://www.moxa.com/Moxa/media/PDIM/S100000327/moxa-iologik-e1200-series-manual-v15.2.pdf) I seem to recall a version specific manual when I started using them years ago, but can’t find now… OK, so I RTFM and page 100 covers it… sorry to have wasted 17 characters’ worth of your day Phil (: ---
