2. Configurable Features Channel Active Each channel can be configured as either active or inactive If a channel is inactive it is not scanned and a value of 0 is returned by the module Low Alarm Limit and High Alarm Limit Each input channel can have a low alarm limit and a high alarm limit If an input reaches one of its limits the module reports the actual value and sends the appropriate diagnostic input bit Alarms do not stop the process or change the value of the input Alarm limits can be set anywhere over the dynamic range of the signal The range for each is 32 768 to 32 767 The high alarm limit must be greater than the low alarm limit If alarm reporting is not wanted alarm limits can be set beyond the dynamic range of the signal so they will never be activated Scaling The module converts electrical signals either current or voltage as configured into digital output values for the CPU or NIU By default the module converts this data from 1 millivolt or 1 microamp internal units for convenience in scaling and comparing to actual meter measurements The module s default scaling can be changed to tailor the data for a specific application Typically engineering units represent millivolts or microamps But they may also represent physical units such as degrees or centimeters per second When reconfiguring scaling it is important to be sure that the chosen Engineering Units values would not result in Overrange or

Overrange or Underrange output levels The scaling for each channel can be configured independently Scaling is configured by selecting corresponding low and high engineering units values and low and high internal values counts for two points During operation the module will use the straight line defined by these two pairs of configured scaling values to convert internal values to current or voltage signal levels that represent appropriate engineering units Scaling Values for 1mV or 1uA Engineering Units For many applications the engineering units are either millivolts or microAmps These units are easy to scale Simply use the table below to find scaling values that are appropriate for the channel s configured range Enter this engineering units value 4mA to20mA 4mA Low 4 000 Low 4 000 a ioma ee ee 10 volts to 10 0 volts Low 0 Low 4 000 OmA to20mA OmA Low 0 Low 0 10 volts to 10 5 volts Low 5 000 Low 5 000 Examples Output Range Span Units microAmps
