Configuration on PI Interface NodeIt is recommended to use the ICU to create the iorates.dat file over creating this file manually. User desiring to manual create the iorates.dat file should use the following procedure. For the following examples, assume that the name of the PI tag is inf001, and that the name of the I/O Rate on the home node is inf001. Windows NodesEdit/Create a file called iorates.dat in the PIHOME\dat directory. The PIHOME directory is defined either by the PIPCSHARE entry or the PIHOME entry in the pipc.ini file, which is located in the %windir% directory. If both are specified, the PIPCSHARE entry takes precedence. Since the PIHOME directory is typically C:\Program Files\PIPC, the full name of the iorates.dat file will typically be C:\Program Files\PIPC\dat\iorates.dat. Add a line in the iorates.dat file of the form: inf001, # where inf001 is the name of the I/O Rate Tag and # corresponds to the first instance of the /ec=# parameter in the startup command file. # can be any number between 1 and 34 or between 51 and 200, inclusive. However, it is best to use an event counter, #, that is not equal to 1 because 1 is the default event counter for UniInt‑based interfaces. To specify additional rate counters for additional copies of the interface, create additional I/O Rate tags and additional entries in the iorates.dat file. The event counter, /ec=#, should be unique for each copy of the interface. Set the /ec=# parameter on the startup command file of the interface to match the event counter in the iorates.dat file. The interface must be stopped and restarted in order for the I/O Rate tag to take effect. I/O Rates will not be written to the tag until 10 minutes after the interface is started. A message in the pipc.log file will indicate if the I/O Rate tag was properly configured and loaded. Download 1.93 Mb. Share with your friends:
