As showed in the figure, to connect a load cell to the PL260 it is necessary to:
• Create the voltage (max 5 Vdc) to supply the cell through the analogue
output AQ4.
• Connect the load cell signals + and – to the analogue inputs AI1 (signal +)
and AI2 (signal -) for reading the differential voltage generated.
• Configure the reference to convert input AI1 on AI2 (SM82 = 2).
• Configure analogue input AI1 on 0..20 mV (SM40 = 4).
