AI Inputs Channel 1
The data for the first analog channel can be found under AI Inputs Channel 1.
• 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: with activated limit 1 (object 0x80x0:07 [
}
37] = 1) means
1: value less than limit 1 (set in object 0x80x0:13 [
}
37] )
2: value greater than limit 1 (set in object 0x80x0:13 [
}
37] )
3: value equal to limit 1 (set in object 0x80x0:13 [
}
37] )
• Limit 2: with activated limit 2 (object 0x80x0:08 [
}
37] = 1) means
1: value less than limit 2 (set in object 0x80x0:14 [
}
37] )
2: value greater than limit 2 (set in object 0x80x0:14 [
}
37] )
3: value equal to limit 2 (set in object 0x80x0:14 [
}
37] )
• Error: This bit is set if overrange or underrange was detected.
