CPU 317T: Technology Functions
6-188 A5E00251798-03
Input parameters
Parameter Data type Start value Description
CamTable INT 0 Number of the technology DB
Execute BOOL FALSE Starts at the positive edge
Mode INT 0 Interpolation mode:
Value = 0: Linear interpolation
Value = 1: Cubic splines (cam path through the
interpolation points)
Value = 2: Bezier splines (cam path along the
interpolation points)
Output parameters
Parameter Data type Start value Description
Done BOOL FALSE TRUE: Cam disk is available for synchronous
operation
(TRUE is also indicated if an
empty cam disk was interpolated)
Busy BOOL FALSE TRUE: Command is busy
Error BOOL FALSE
TRUE: Command initiation
with error.
The command is not executed; the cause is
found in the ErrorID.
FALSE: Command initiation
without error
ErrorID WORD FALSE
ErrorID of the Error output parameter.
Warning
The interpolation of cam disks with many interpolation points or polynomials may
take a relatively long time. Other technology objects can not accept any new
commands within this period of time. This also applies to MC_Stop commands !
Note that you can not cancel commands without defined termination
("MC_MoveVelocity", for example) within this time.
If the monitoring time for command execution is set too short in S7T Config, the
interpolation may lead to a time-out and, thus, to a STOP of the Technology CPU.
