DL06 Newbie...looking for an auto-toggle (pulse generator)

[Rivinski]

I am new to PLC's and ladder logic, so please bear with me.  I am trying to hack/connect an ABB softstarter as a modbus slave to a DL06.  I have to read 3 analog word registers on the starter, giving me the 3 phase currents for monitoring purposes.  Well, I haven't gotten very far because I can't find a way to automatically toggle the program on/off every second so that the data will update w/out my having to manually toggle the element.  Is there an element or combination thereof that will do this.  Basically, I want to read those phase currents every second, not just once.  Please help!!

Just use SP4. It will toggle on an off every second.
