FB “Read Present Unit ON Time”
FB Name _Dnet204_GetONTime_PV
File Name _Dnet204_GetONTime_PV10.cxf
Functional Overview Reads the present Unit ON time(conduction time)from slaves connected to DeviceNet.
Program Example
When contact A is set to ON, current value of the unit conducting period of the specified slave of
the node address 15 is read out and outputted to D0. As a result, &10 is stored in D0.
Variables Table
