If you are using a level instrument and just want a few levels, then this method works fine. Ifyou have a weigh feeder, then this method is not supported because there is too much data to be passed.

  • Page 23: Primary Index

    Primary Index An index that relates to an input or output is called a Primary Index. (On some older Siemens Milltronics products the primary index is called a point.) Example: P111[3] = 52 means P111 (Relay Control Function) for relay 3 is set to value 52.

    (the primary index relates to the transducer input). An index that relates to a previously indexed parameter is called a secondary index. (On some older Siemens Milltronics products the secondary index is called a mark.) Example: P054[1,3] = 1.6m means P054 (Breakpoint Levels) for breakpoint 3 on transducer 1 is set to 1.6m...

    Primary Index, Secondary Index. This is a hand-shaking method where the user specifies the parameter number, secondary index, decimal place, and format, then the SmartLinx writes into a certain area all 10 primary indexes of that parameter. Using Multiple Parameter Access (MPA) In the output table of the PLC (Write Block) write the values for the parameter number, secondary Index, decimal place and format in the correct location.

    Troubleshooting Generally In all cases, first check that the SmartLinx module has passed its on-going built-in self test (host instrument parameter P790). The result should be PASS. If FAIL is indicated, the module could be installed incorrectly, the module could be defective, or the module connector on the Siemens Milltronics host instrument could be defective.
  • Page 55 Check that no other host instruments connected to this remote I/O link have been set to the same rack number and starting group as the Siemens Milltronics host instrument. Make sure the Siemens Milltronics host instrument is connected and terminated correctly and in agreement with all Allen-Bradley remote I/O wiring practices (please contact your Allen-Bradley representative for the latest guidelines).
