[Selection of pulse counting software]
The pulse counting software to be installed to PLC differs depending on the IP address of the PLC.
Refer to Table 8-4 for selection. One set of PLC can count the measuring instruments up to 32 sets.
(3) Setting item
For this method, the contents of setting differ depending on the load to be measured. Conduct each
setting by following the setting items shown in the electric power pulse counting (apportioning) method.
