YRC1000 Concurrent I/O Auxiliary Addresses Retaining State During Power Cycle

Keywords: CIO, Retain, Latch, Retentive, Power Off, Cycle Power

Concurrent I/O auxiliary addresses (7XXXX Series) can retain their state during a power cycle by setting parameters S4C080 - S4C095.

Each individual parameter can retain 60 groups of auxiliary addresses, and the parameter value determines which addresses (in groups of 4) retain.  

For Example, 

     S4C080 - Range is  #70010 To #70647

     This range is divided into 16 sub ranges, each sub range corresponding to a binary value in the parameter

D00 - #70010-#70047 - Set S4C080 to 1 to retain these addresses

D01 - #70050-#70087 - Set S4C080 to 2 to retain these addresses

D02 - #70090-#70127 - Set S4C080 to 4 to retain these addresses

D03 - #70130-#70167 - Set S4C080 to 8 to retain these addresses  

D04 - #70170-#70207 - Set S4C080 to16 to retain these addresses

D05 - #70210-#70247 - Set S4C080 to 32 to retain these addresses

D06 - #70250-#70287 - Set S4C080 to 64 to retain these addresses

D07 - #70290-#70327 - Set S4C080 to 128 to retain these addresses

D08 - #70330-#70367 - Set S4C080 to 256 to retain these addresses

D09 - #70370-#70407 - Set S4C080 to 512 to retain these addresses

D10 - #70410-#70447 - Set S4C080 to 1024 to retain these addresses

D11 - #70450-#70487 - Set S4C080 to 2048 to retain these addresses

D12 - #70490-#70527 - Set S4C080 to 4096 to retain these addresses

D13 - #70530-#70567 - Set S4C080 to 8192 to retain these addresses

D14 - #70570-#70607 - Set S4C080 to 16384 to retain these addresses

D15 - #70610-#70647 - Set S4C080 to 32768 to retain these addresses

If multiple sub ranges are desired, add the binary value of sub range and set parameter to the added result. 

    For example:

    Desired retained sub range addresses are #70210 - #70247 & #70250 - #70287.  Add 32+64 = 96.  Set S4C080 to 96.
