<PLS> 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 true if block is enabled.
OUTPUT Bit Goes true when Counter input value is within
the LOWLIMIT and HILIMIT inputs and the
EXECUTE
input is True.
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 Description Range and state
EXECUTE Bit Block enable – Block cannot
execute unless this is
TRUE. True-effective
False-invalidity
LOWLIMIT Long Defines the output enable
window. Minimum value of
counter for OUTPUT output
to go TRUE -2147483648～2147483647
HILIMIT Long Defines the output enable
window. Maximum value of
counter for OUTPUT output
to go TRUE -2147483648～2147483647
COUNTER Long The controlling counter for
the bit A long register containing the
counter value.
DATA02W Addres
s
Address of the first working
register. Two words of register space
are used by this function.
<PLS> Working Register
This table outlines the data in the two 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 A IN oneshotA Reserved
Bit B
IN
firstPass
One shot coil from rising edge of EXECUTE input to initiate
block.
