Input Registers
The following registers are used as inputs to the function block. They select the options
and define the parameters that the user needs to make the function work as necessary.
Input Type Description Range and state
EXECUTE Bit Block enable – Block cannot
execute unless this is
TRUE. Rising edge initiates block
TRUE – Block enable
FALSE – Block disable, set all
outputs to zero and off
DST-TIME Bit Selects master or time for
offset duration TRUE – Master position is
used for duration
FALSE – Time is used for
duration.
M-S-PAIR Word Defines which Master-Slave
pair is updated in RDA 1 to 10 value. Any other
value will cause the error
output to go on
DURATION Long Depends on DST-TIME
setting. Either time in msec
or distance master must
travel to complete change in
offset. -2147483648 to
2147483647.
If in time mode no negative
numbers are allowed.
OFFSET Long Relative shift to be applied
to the master. RDA will hold
absolute offset value level
(The RDA offset is ML56**4) -2147483648 to 2147483647
DATA23W Address Address of the first working
register.
Twenty-three words of
register space are used by
this function.
Block Fault Condition
The following table outlines several situations that may cause an error, and will turn on
the blocks “Error” output bit. The block “Error” output will cleared if the EXECUTE bit
goes low, but the Error ID (MW3**81and MW3**82) will remain in the RDA. To reset the
Error ID, use the Alarm Reset Function Block.
The following table outlines several situations that may cause an error.
Internal Fault bit Cause Note
Inrng1
AB00000E MSTRSLV value
out of range Inrng1 must be high if execute is on or an
error will occur. MSTRSLV must have a
value from one to ten for this bit to be on.
Sets RDA Error ID (MW30181) bit 3.
