TECHNICAL NOTE
Input and Output Register Map
Output Registers
The following registers are used as outputs from the function block. They can be
monitored by the LadderWorks program to check the execution of the function.
Output Type Description
RUNNING Bit Goes high while offset value is being updated in RDA
and there are no errors
DONE Bit Goes high when offset change is complete in RDA
ERROR Bit Goes high if any block errors occur
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 Home function work as
necessary.
INPUT TYPE Content Range of setting 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 position [count] or
time [ms] 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 or distance master
must travel to complete change in
offset. Distance: 2147483648～
2147483647 [count]
Time: 0-2147483647 [ms]
OFFSET Long Total value offset in RDA will
change. -2147483648～2147483647
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.
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.
