In the –10 to +10V range, lues between –32768 to 32767 are sent or received from the over an input voltage range of –10 to +10V. The two current ranges are , and . In each of the current ranges, lues between 0 and 32767 are reported back from the module to sent to the module for the entire range.

Each has a low limit alarm lue (ALARM LO) and a high limit alarm lue (ALARM HI). These alarm lues cause %I points to be set as indicated in the tables on page 3-95 and 3-96. lues can be entered in all high and low limit fields. lues entered without a sign are assumed to be positive. The allowable lues are shown in the following table.

When an is t in ramp mode, new lues entered in the corresponding %AQ reference cause the to step to the comnded lues as shown in Figure 3-52. When an is in ramp mode, new lues entered in the corresponding %AQ reference cause the to ramp to the given lues using ramp riables which have been assigned to the using ladder logic. The ramp is composed of steps taken every 1 millisecond. %AQ LUE CHANGES EXAMPLE IN RAMP MODE EXAMPLE IN STANDARD MODE TIME FIL LUE CORRESPONDING TO NEW %AQ LUE Figure 12-7. Behavior in Ramp Mode and in Standard Mode The default mode of both s is standard mode. Ramp mode and ramp riables are set using an E2 in ladder logic as described below. The mode of each is set independent of the mode of the other . When an is in ramp mode, two lower-level modes can be used to specify the ramp slope: time mode, in which the user provides the total ramp time in milliseconds, and step mode, in which the user provides the step in %AQ counts that will be taken every 1 millisecond. Setting the Ramp Mode An E2 is used to change the ramp mode of an . This is the same that is used to change the input alarm limits of the module and clear the %I error code. When the module receives the , the first word, or comnd word, is checked to determine whether the ramp settings or alarm limits are being changed or whether the %I error code is being cleared. When step mode is specified, the second data word contains the ramp step in %AQ counts. lid step lues range from 1 to 32000. The direction of the ramp is determined when the lue of the corresponding %AQ reference changes. Once the ramp mode and step have been set, changing the corresponding %AQ lue causes the to ramp to the new lue. When time mode is specified, the second data word contains the total time in milliseconds it will take for the to ramp from the present lue to the fil lue. The present and fil lues are specified by the old and new lues of the corresponding %AQ reference. lid ramp time lues range from 1 to 32000, which correspond to ramp times of 1 millisecond to 32 seconds. Once the ramp mode and time have been set, changing the corresponding %AQ lue causes the to ramp to the new lue. If an E2 is issued to the module to change the ramp settings while the indicated is in the process of ramping, the new ramp settings will
