With Module Interrupt Reporting enabled, this parameter controls interrupts for Over-temperature module faults. Range Type Disabled Current Sets up the type of output to be used for each channel. Choices are: Disabled Voltage, Disabled Current, Current/Voltage. Range (Only for Range Type Current/Voltage) -10 Vdc to +10 Vdc For Current/Voltage: -10 Vdc to +10 Vdc, 0 Vdc to +10 Vdc, 4mA to 20 mA, 0mA to 20 mA. Channel Value Format 32-bit Floatingpoint 16-bit integer or 32-bit floating-point PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 475 Module Parameters (Continued) Outputs Default Force to Default Value Controls the state the output will be set to in Outputs Disabled mode (stop), if a fault occurs, if power is lost, or if the configuration is cleared. Choices are Hold Last State, or default to a specific configured default value. 10.4.5.1.3 Range Type Each channel on the module that will be used should be configured for Current/Voltage. Its voltage or current range and other parameters can then be configured as needed. If the channel output will not be used and is not wired, select either “Disabled” option. If a channel is disabled, it is not necessary to configure any of its other parameters. If the channel is wired to a current output, but is not being used, select "Disabled Current". This will set the output current of that channel to 0mA (the output voltage of that channel will be non-zero). If the channel is wired to a voltage output, but is not being used, select "Disabled Voltage". This will set the output voltage of that channel to 0V (the output current of that channel will be non-zero). 10.4.5.1.4 Output Defaults If Hold Last State is enabled, an output will hold its last commanded value when the CPU indicates Outputs Not Enabled, or if one of the fault conditions listed below occurs. If Hold Last State is disabled, the output is commanded to go to the Default Value. The Default Value must be set within the selected output range. If both Default Value and Ramp Rate are enabled, the channel will ramp to the default value. Fault conditions are: ? CPU outputs are not enabled. ? Backplane power is not ok. In that case, there is no ramping, even if ramping has been enabled. ? Loss of communications from CPU. ? Loss of I/O communications. ? Loss of field power. Outputs Default Notes ? Hot Removal of the module in an I/O Enabled mode will cause all outputs to Hold Last State (even channels configured for Force to Default Value). If that operation is not desirable, the outputs can be forced to default by first turning off field power and removing the Terminal Block of this module before hot-removing the module. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 476 ? Resetting the module using SVC_REQ 24 causes all channels to Hold Last State even if Default Value is configured. The application program must handle output defaulting before execution of the Service Request. ? Default Ramp Rate configuration is ignored if backplane power from the power supply is lost. Channels configured for Default Value go to the default value immediately. The first time a configuration is stored following a return of backplane power, the Default Ramp rate is not used. Any channel configured for Default Value goes to its default value immediately.
