Input from I/O Input data from I/O modules.
Gather V-Para Gather V-Para data from the other control card.
Execute program Execute the program that is in the control card.
Make RAW data Make the RAW DATA of the control card.
Output to I/O Output data to I/O modules.
Partial Tracking Tracking the data for the redundant configuration. These data are the changed tag
parameters and the changed download data of control card.
Tracking Tracking the data of control card and the data of Tag.
Partial Equalize Equalize the data that was changed by the engineering tools.
Note) In the case of a single configuration, processing of partial tracking, tracking, and partial equalize is
not performed.
The sum total of the processing time of each control card assigned to the same scan is scan execution
time. The scan execution time can be checked with an engineering tool.
The processing time of control card depends on application program. When many control cards execute
the very big application program, no processing of control cards may not be complete within scan setting
time. Please check the scan execution time, and adjustment of scan setting time.
The performance of the example of large-scale application of each control card is shown below.
Note that it depends on the CPU module (ILPU3) firmware revision number.
for V1.** for V2.**
VLCXP5 200 function blocks, 32 V-Para about 30ms about 21ms
VPCPX2 150 function blocks, 64 V-Para about 80ms about 60ms
VACPX2 150 function blocks, 32 V-Para about 30ms about 21ms
VSCPX2 about 60ms about 40ms
Note) The above numerical value is a ear value. Processing time influences according to the kind of functional
block currently used.
Note) The operation to change a scanning classification (High-speed scan / Main scan) or to change a scan time
become the initialization of control card.
