6.8 Counting energy values Input 1 is connected to the S0 output of an energy consumption meter<br />
(100 pulses/kWh). The 4 byte counter value is displayed on the bus as Wh.<br />
It is sent on the bus every 30 seconds and if the value changes by 100 Wh.<br />
Input 1<br />
<strong>Universal</strong> interface<br />
<strong>US</strong>/U x.2<br />
Telegr. counter value 4 bytes 1/1/1<br />
Request counter values 1/1/2<br />
Differential counter overflow 1/1/2<br />
Parameter settings for input 1:<br />
100 pulses per kWh means 1 pulse per 10 Wh. The counter is therefore<br />
increased every impulse by the value 10 (factor = 10).<br />
The differential counter generates an overflow every 100 Wh, which in turn<br />
requests a new counter value.<br />
