Function blocks
Function blocks for TwinSAFE logic components 177
3.26.4.2 Inputs
Name
Permitted type
Description
Automatic
safeBOOL
0: Normal operation
1: Automatic mode (no parameter verification)
SettingMode
safeBOOL
Setting-up mode. Internal parameters can be changed if the
input is set to 1.
Position
analog
(UINT16/UINT32)
Press position. The position value must be verified reliably
from several analog values or made available to the function
block by another other safe method, according to the
required SIL/performance level.
Reset
safeBOOL
BOOL
Reset input. Before each press start a falling edge must be
detected at the Reset input. Only then may a motion take
place or the TDC exited.
Press_Started
safeBOOL
BOOL
If the input is active, a motion or change of position is
expected when a logical 1 is encountered at the input. To
this end the parameter PressStartDelayTime,
MoveDetectionTime and MinPositionChange must be set.
TDC1_LowerLimit
Fixed value
(UINT16/UINT32)
The input or parameter TDC1_LowerLimit indicates the
lower limit of the TDC in the "left" half of the press. The value
must be greater than the BDC (bottom dead center) and less
than TDC1_UpperLimit.
TDC1_UpperLimit
Fixed value
(UINT16/UINT32)
The input or parameter TDC1_UpperLimit indicates the
upper limit of the TDC in the "left" half of the press. The
value must greater than TDC1_LowerLimit and less than
MaxPosition.
TDC2_LowerLimit
Fixed value
(UINT16/UINT32)
The input or parameter TDC2_LowerLimit indicates the
lower limit of the TDC in the "right" half of the press. The
value must be greater than TDC2_UpperLimit and less than
BDC_LowerLimit.
TDC2_UpperLimit
Fixed value
(UINT16/UINT32)
The input or parameter TDC2_UpperLimit indicates the
upper limit of the TDC in the "right" half of the press. The
value must be greater than 0 and less than
TDC2_LowerLimit.
BDC_LowerLimit
Fixed value
(UINT16/UINT32)
The input or parameter BDC_LowerLimit must be less than
MaxPosition/2 and greater than TDC2_LowerLimit.
BDC_UpperLimit
Fixed value
(UINT16/UINT32)
The input or parameter BDC_UpperLimit must be greater
than MaxPosition/2 and less than TDC1_LowerLimit.
OverrunMax
Fixed value
(UINT16/UINT32)
The input or parameter OverrunMax must be disabled or set
to 0.
BackwardsMove
safeBOOL
In pendulum mode the input must be inactive.
OverrunCam
safeBOOL
The input OverrunCam must be inactive.
UpwardCam
safeBOOL
The input UpwardsCam must be inactive.
