<![CDATA[Toggle a Modbus Relay IO control every two seconds]]>Hi,

I have successfully interfaced some PLC IO modules with Mango and able to both read and write to them through Modbus.

In one of our customer requirement, we need to toggle the relay output (connected to Modbus) every two seconds. What's the way out?

Thought of cron jobs, but I think it does not allow you to schedule in seconds.

Need help,

Thanks,
Narayana Swamy
