Bit 0: Input 7 >= High Limit
Bit 1: Input 7 >= High-High Limit
Bit 2: Input 7 <= Low Limit
Bit 3: Input 7 <= Low-Low Limit
Bit 4: Input 7 Calibration Error
Bit 5: Input 7 Configuration Corrupted
Bit 6: Input 7 Incorrect Input Type
Bit 7: Unused (will read as 0)
Bit 8: Input 8 >= High Limit
Bit 9: Input 8 >= High-High Limit
Bit 10: Input 8 <= Low Limit
Bit 11: Input 8 <= Low-Low Limit
Bit 12: Input 8 Calibration Error
Bit 13: Input 8 Configuration Corrupted
Bit 14: Input 8 Incorrect Input Type
Bit 15: Unused (will read as 0)

where Input Type is chosen from one of the following:
0 = No Input Type Selected
40 = Input is 0
– 10 Volts
41 = Input is 2
– 10 Volts
42 = Input is 0
– 5 Volts
43 = Input is 1
– 5 Volts
44 = Input is 0
– 1 Volt
60 = Input is 0
– 20 mA
61 = Input is 4
– 20 mA
62 = Input is 0
– 50 mA
63 = Input is 10
– 50 mA
NB: Set input resistor value for current inputs
Display Format for each Input
These bits set the data format for each analogue input either in physical units
(Volts/milliAmps) or as a percentage of full scale.
Bit = 0: Input reads as an integer representing milliVolts or microAmps
(dependent upon type selected)
Bit = 1: Input reads as an integer representing % of full scale x 100.
(i.e. 0 to 10000 = 0 to 100% of range of selected Input Type)
Individual bits are allocated as follows:
25
Bit 0: Input 1 Display Format
Bit 1: Input 2 Display Format
Bit 2: Input 3 Display Format
Bit 3: Input 4 Display Format
Bit 4: Input 5 Display Format
Bit 5: Input 6 Display Format
Bit 6: Input 7 Display Format
Bit 7: Input 8 Display Format
Bits 8 to 15 must be set to 0
