linear relationship between two sets of corresponding values. They do not have to be the limits of the output. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 479 Example In this example, the application should interpret 32000 counts as +10 Vdc and –32000 counts as -10 Vdc. The following channel configuration will scale a ±10 Vdc output channel to ±32000 counts. Channel Value Format = 16-bit Integer High Scale Value (Eng Units) = 32000.0 Low Scale Value (Eng Units) = -32000.0 High Scale Value (A/D Units) = 10.000 Low Scale Value (A/D Units) = -10.000 Voltage -10,000 +10,000 -32,000 Counts 32,000 Figure 309: Channel Scaling Example PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 480 Channel Parameters (Continued) Parameter Default Description High Alarm (Eng Units) The defaults depend on the configured Range. All of the alarm parameters are specified in Engineering Units. When the configured value is reached or below (above), a Low (High) Alarm is triggered. Low Alarm (Eng Units) Outputs Enabled Ramp Rate (Eng Units) 0.0 The rate in Engineering Units at which the output will change during normal operation. Default Ramp Rate (Eng Units) 0.0 The rate in Engineering Units at which the output will change if a fault condition occurs or if outputs are not enabled. Output Clamping Enabled Disabled Enabled / Disabled. Refer to description below. Upper Clamp Limit (Eng Units) The defaults depend on the configured Range. The Upper Clamp Limit must be greater than the Lower Clamp Limit. This parameter can be used to restrict the output to a range that is narrower than its configured Range Type. For example, a channel configured for –10 Vdc to +10 Vdc could be restricted to -8V to +7.5V. Lower Clamp Limit (Eng Units) Default Value (Eng Units) 0.0 If Hold Last State is disabled, the output is commanded to go to the Default Vale when the CPU is not in Outputs Enabled mode or under certain fault conditions. User Offset (Eng Units) 0.0 A configurable value that can be used to change the base of the channel. This value is added to the scaled value of the channel before alarm-checking. 10.4.5.3 Lower, Upper Clamp and Alarms Alarms can be used to indicate when the module has been commanded to meet or exceed the configured high or low limits for each channel. These are set at six configurable alarm trigger points: ? High Alarm and Low Alarm ? Upper Clamp and Lower Clamp ? Over-range and Under-range Alarm Each alarm is individually configurable per channel to generate diagnostics bit status, fault alarms, or interrupt alarms. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 481 If a channel is commanded higher than the Upper Clamp value, the output is set to the Upper Clamp value and an Upper Clamp condition is indicated. If a channel is commanded lower than the Lower Clamp value, the output is set to the Lower Clamp value and a Lower Clamp condition is indicated. The High and Low Alarm checks are performed on the engineering units output value after possibly being adjusted by ramping, clamping, and fault conditions. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 482 Channel Parameters (Continued) Parameter Default Description Diagnostic Reporting Enable If Diagnostic Reporting is enabled, the additional parameters listed below can be used to enable specific types of alarms. Disabled Diagnostic Reporting Enable options are used to enable reference memory reporting of alarms into the Diagnostic Reference area. Fault Reporting Enable options enable fault logging of alarms into the I/O Fault Table. These parameters enable or disable the individual diagnostics features of a channel. When any of these parameters is enabled, the module uses associated parameters to perform the enabled feature. For example, if Over Range is enabled in the Diagnostic Reporting Enable menu, the module will set the Over Range bit in the Diagnostic Reference for the channel. If any of these parameters is disabled, the module does not react to the associated alarm conditions.
