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 = 1) means
  1: value less than limit 1 (set in object 0x80x0:13)
  2: value greater than limit 1 (set in object 0x80x0:13)
  3: value equal to limit 1 (set in object 0x80x0:13)
• Limit 2: with activated limit 2 (object 0x80x0:08 = 1) means
  1: value less than limit 2 (set in object 0x80x0:14)
  2: value greater than limit 2 (set in object 0x80x0:14)
  3: value equal to limit 2 (set in object 0x80x0:14)
• Error: This bit is set if overrange or underrange was detected.

AI Inputs Channel 2

The data of the second analog channel have the same structure as those of the first channel.

AO Outputs Channel 3

The data for the third analog channel can be found under AO Outputs Channel 3.

AO Outputs Channel 4

The data of the forth analog channel have the same structure as those of the third channel.
