• When a blank is included in $VAR_NAME, assignment is not
performed. Also, when using @, be sure to specify @
immediately after a variable name without inserting a blank.
• When successive assignment is performed, the number of %R’s
used for one element varies depending on the type of assigned
data. Confirm the explanation of each data.
• When specifying @, follow the format “@number.number”. A
period ( . ) is used between the numbers. Be sure to specify @
immediately after the variable name.
6.11.2 Improving Communication Efficiency
• Read/Write of I/O signals is faster than read/write of %R’s
assigned with $SNPX_ASG. The speed of read/write of %R may
be slower during program execution. On the other hand,
read/write of I/O signals is not affected by program execution.
When emphasis is placed on the communication speed, it is
recommended that the use of %R be avoided if possible.
• Data conversion of a position register between the Cartesian
coordinate and joint formats requires a significant amount of
time. In position register assignment, @ can be used to assign
only those elements that are actually required. This can improve
communication efficiency. In addition, when data is read through
CIMPLICITY, using the same data format as that of the actual
position register eliminates the necessity of data conversion, thus
improving communication efficiency.
• CIMPLICITY sometimes automatically reads from an address
that actually is not used. In such a case, to prevent the slowing of
communication speed, do not assign unnecessary data whenever
possible. In addition, assign %R’s so that they are as close as
possible to compact the %R area for read/write. This can
improve communication efficiency.
6.11.3 Version Of Communication Function With CIMPLICITY
The value of $SNPX_PARAM.$VERSION specifies the version of
communication function with CIMPLICITY. Whe
$SNPX_PARAM.$VERSION does not exist, the version is 1.
