PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Output Modules 452 10.3.12.1 Thermal Derating, Current Mode: ALG708 Module IC695ALG704 has no thermal derating. Module IC695ALG708 has no thermal derating in voltage mode. Thermal derating for module IC695ALG708 in current mode is displayed in Figure 305. Figure 305: Thermal Derating Curves for ALG708 at selected Voltage Levels (Current Mode only) 10.3.13 Configuration: ALG704 and ALG708 10.3.13.1 Module Parameters Parameter Default Description Outputs Reference Address %AQxxxxx Starting address for the output data of this module. This defaults to the next available %AQ block. Outputs Reference Length ALG704: 8 The number of words used for the output data of this module. This parameter cannot be changed. ALG708: 16 Output Command Feedback Reference Address %AIxxxxx Stating address for the command feedback data of this module. This defaults to the next available %AI address after a non-zero length is configured. Output Command Feedback Length 0 The number of words used for the command feedback data of this module. Length defaults to 0. It can be set to 8 or 16, depending on the module type being configured. Diagnostic Reference Address %Ixxxxx Starting address for the channel diagnostics status data. This defaults to the next available %I block. 50 51 52 53 54 55 56 57 58 59 60 1 2 3 4 5 6 7 8 Ambient (Degrees C) Channels Vuser = 26.5V Shorted the status data of this module. This defaults to the next available %I block. Module Status Reference Length 0 Read Only. The number of bits (0 or 32) required for the Module Status data. Default is 0, which means mapping of Module Status data is disabled. Change this to a non-zero value to enable Module Status data mapping. 10.3.13.1.1 Analog Output Commanded Feedback The module returns a copy of the analog output data received from CPU in its corresponding channel analog input shared memory. Output Feedback can be monitored to check the values being sent to the channels. The data is in the same scaled format as the output data for each channel. During normal operation, this feedback data should match the actual output data after one or more PLC scans of module inputs. During faults, ramping, over-range, and clamping conditions, the analog output data may differ from the commanded output. 10.3.13.1.2 Over-Temperature If Over-Temperature is enabled, the module generates an Over-Temperature alarm if the internal temperature of this module is too great for the number of outputs that are on at the same time.
