Configuration details for basic parametersare given in the following pages.3.2.2.1 Basic Module ParametersThe PNS parameters define how the IO-Controller scans and stores the PNS data.Default values are provided by the module’s GSDML file.Input Data / Output Data: The address in the IO-Controller’s reference memory for themodule’s data.Length: The length of the input /output data is fixed and cannot be edited (NonConfigurable).3.2.2.2 Additional Module ParametersAdditional module parameters vary, depending on the module type. Some modules have onlya few parameters. Others have several. The additional parameters that must be configuredfor more complex modules are explained in the individual module documentation.On Failsafe: When the module has outputs, this field specifies how the PNS will handle themodule’s output data if it loses communication with the IO-Controller. Select either Hold LastState or Failsafe Value (For Analog modules) or ON/OFF (For Digital modules). Thisselection has to be made for each channel in the module. If Failsafe Value is chosen, failsafevalues can be set up on a per-channel basis. If the Failsafe time out is set to ‘0’, Failsafe isdisabled.Note: PAC8000 analog and digital modules latch their last outputs when configured forHold Last State and hold that value as long as field power remains on to the module.Clear Latch: These control bits of the module clears the Latch of the selected channel. If thechannel’s Latch is enabled in the configuration and got Latched to an input, by using thecorresponding bit user can clear the Latch. As long as the Latch Bit is set to 1 the Latch onthat channel will be disabled. This control bit is available to DI modules with pulse countersenabled.Clear Counter: These control bits of the module clears the Counter of the selected channel. Ifthe channel’s Counter is enabled in the configuration and has been counting the pulses, byusing the corresponding bit user can clear the Counter. As long as the Clear Counter Bit isset to 1 the Counting on that channel will be disabled.3.2.2.3 Configuring the Module ParametersPlease refer to the PAC8000 IO module’s manual (8000-2/x Series Modular I/O GFA-1779)for configuration details
