Remote Transmitter Error Up or Down

A second feature of your input modules that affects use of the Remote Fault 

alarm is the Remote Transmitter Error Up or Down feature. Used in 

conjunction with the High Low Error level, this feature designates whether 

remote faults are displayed with input signal readings beyond the high or low 

signal levels normally used by the module.

When setting the Remote Transmitter Error Up or Down feature in your 

programming software, set this feature’s bit to 0 to select up. Set the bit to 1 to 

select down.

For more information on Remote and Local Fault alarms, see page 1-5.

High Low Error Level

High Low Error level sets the high and low signal levels at which your input 

modules will indicate a signal fault. This feature works in conjunction with the 

Remote Transmitter Error Up or Down.

If the Remote Fault Alarm feature is enabled and a remote fault occurs, the 

module will detect and report the fault, depending on how the High Low 

Error level is configured.

Use your programming software to set the high or low error levels.

Input Filter Cutoff

Eight available input filter settings allow you to choose the best rolloff 

frequency for input channels on your I/O module. When choosing a filter, 

remember that time filter selection affects your input signal’s accuracy.

For example, if you choose the highest frequency of 1200Hz (filter 0), signal 

noise is more likely to affect the reading, but the slowest frequency

of 0.5Hz (filter 7) provides the most accurate signal due to incoming

noise filtering.
