Working Registers
This table outlines the data in the eight registers used by the function block. There is
not usually any need for the user to access any of these bits directly.
Register No. Type Name Description
AW00000
Bit 0 IN execute EXECUTE input (XB000000)
Bit 1 IN distmode DST-TIME input (XB000001)
Bit 3 Working zerodiv
If duration is set to zero for one scan change, this turns on for
one scan (one-shot)
Bit 6 Working distShft_init
High for one scan to initialize for master position shifting if first
pass is high and DISTMODE is high. To initialize for master
position control of offset.
Bit 7 OUT running Directly controls YB000000 (RUNNING Output)
Bit 8 OUT complete Directly controls YB000001 (DONE Output)
Bit 9 OUT error Directly controls YB000002 (ERROR Output)
Bit A Working oneshotA Reserved
Bit B Working firstPass High for first scan of EXECUTE being high
Bit D Working timeshft_init
High for one scan to initialize for time based shifting if first pass
is high and DISTMODE is low.
Bit E Working inrng1
On if Execute is on and MSTSLAVE (XW000001) value is in
range
AW00001 Working
scans_per_shif
t Number of scans needed to complete a time based
shift.
AW00002 Working iStore Pass through value for i.
AW00003 Working mstrSlv MSTSLAVE input (XW000001) – 1.
AL00004 Working maxShift_scan
Maximum counts allowed to scale per scan on a
time based scan.
AL00006 Working posLAUlim Positive value of maxShift_scan
AL00008 Working negLAUlim Negative value of maxShift_scan
AL00010 Working total_Shifted
Amount Scale Offset has changed during the
execution of the block.
AL00012 Working shiftvalue
Relative value to change the RDA (ML03**8) cam
scale for that scan.
AL00014 Working startmaster
Value of Master counter at start of block for
position based move.
AL00016 Working
RelativeCha
nge Difference between set scale value and current
scale value in RDA.
AL00018 Working desired_shift
Total amount needed to be scaled for the master
position mode.
AL00020 Working timemod Reserved.
AW00022 Working Revision Revision Level of the function block.
