Underrange: Value of the analog input is less than 0/4 mA or -10/0 V
Overrange: Value of the analog input is greater than 20 mA or +10 V
Limit 1 / Limit 2: with activated Limit 1 (object 80x0:07 = 1)/ Limit 2 (object 80x0:08 = 1)
1: means value < Limit 1 (set in object 0x80x0:13) / Limit 2 (set in object 0x80x0:14)
2: means value > Limit 1 (set in object 0x80x0:13) / Limit 2 (set in object 0x80x0:14)
3: means value = Limit 1 (set in object 0x80x0:13) / Limit 2 (set in object 0x80x0:14)
Error: This bit is set if overrange or underrange was detected.
Channel 3 Out Value, Channel 4 Out Value
