Case 1
:
When
Execute
changes from FALSE to TRUE,
Busy
and
Active
change to TRUE. One period
later,
Done
changes to TRUE. Meanwhile
Busy
and
Active
changes from TRUE to FALSE. After
Execute
changes from TRUE to FALSE,
Done
changes from TRUE to FALSE.
Case 2
:
When an error occurs as
Execute
changes from FALSE to TRUE,
Error
changes from FALSE
to TRUE and
ErrorID
shows corresponding error codes.
Error
changes from TRUE to FALSE
and the value in ErrorID is cleared to 0 after
Execute
changes from TRUE to FALSE.
Function Explanation
The TO instruction is used to write data to the specified CR registers of the left-side module and right-side
module.
The positions of left-side and right-side modules are specified by
StationID
. The
StationID
range of right-side
module is 0~7. 0 represents the first extension analog module at the right side. 7 is the eighth extension
analog module at the right side. The
StationID
range of left-side module is 100~107. 100 is the first extension
module at the left side. 107 is the eighth extension analog module at the left side. If
StationID
value exceeds
the specified range for left-side and right-side modules, an error will occur in execution of the instruction.
If the instruction is used to write values to multiple CR registers,
DesPtr
need be defined as the N
th
element
