4.1.15 Low Alarm Register (Register 29)

less than this limit, the channel's corresponding bit in register 18 is

set to one. The value in register 29 is a 15Ćbit plus a signĆbit integer.

This value must be in engineering units if scaling is used. If scaling is

used, this value must be smaller than the Maximum Scaling Value

(register 24) and equal to or larger than the Minimum Scaling Value

(register 25). Unscaled data can range from -4095 to +4095. Note

that if the channel is to be configured for unipolar operation (0V to

10V range), the value in register 29 may have to be changed to

reflect input data in the unscaled range of 0 to +4095.

If register 29 does not contain an alarm value less than the High

alarm value, a configuration error will result in register 22. At

powerĆup, the register is set to a default value of -4085.

4.1.16 Low Low Alarm Register (Register 30)

is less than this limit, the channel's corresponding bit in register 19 is

set to one. The value in register 30 is a 15Ćbit plus a signĆbit integer.

This value must be in engineering units if scaling is used. If scaling is

used, this value must be smaller than the Maximum Scaling Value

(register 24) and equal to or larger than the Minimum Scaling Value

(register 25). Unscaled data can range from -4095 to +4095. Note

that if the channel is to be configured for unipolar operation (0V to

10V range), the value in register 30 may have to be changed to

reflect input data in the unscaled range of 0 to +4095.

If register 30 does not contain an alarm value lower than or equal to

the Low alarm value, a configuration error will result in register 22. At

powerĆup, the register is set to a default value of -4094.

4.1.17 Configuration Command Register (Register 31)

and what action should be taken if an input value is out of range. The
