Configurable functions
Input
Effect
Release
If a release module connected to the input releases the
application (see Tab. 9), the outputs Out1 and Out2 are activated,
depending on the respective status of its other inputs.
This is only the case, however, if the emergency stop input device
connected to the UE 440/470 and integrated in the application is
not actuated.
BDC (machine cycle
contact for the
bottom dead centre)
If the contact is active, the "ESPE/Switch" input is bridged.
For information on evaluating the machine cycle contacts please
refer to Section 4.3.3 "Significance of the machine cycle contacts
for PSDI mode operation" on page 35 and Section 6.2.8
"Machine-cycle contacts" on page 52.
TDC (machine cycle
contact for the top
dead centre)
If the contact is activated, the outputs of the function module are
deactivated.
For information on evaluating the machine cycle contacts please
refer to Section 4.3.3 "Significance of the machine cycle contacts
for PSDI mode operation" on page 35 and Section 6.2.8
"Machine-cycle contacts" on page 52.
If a release module is configured, it checks the release conditions (e.g. actuation of the
reset button or external device monitoring) when the application is started or after the
OSSDs are switched off. The output of the release module signals a logical 1 (releases)
when the necessary input criteria are met (AND link) at
all the inputs used
.
Input
Input criterion
Reset
A reset button connected to the release module was actuated
(signal sequence 0-1-0 present).
Reset2
An input device connected to the release module, for example a
two-handed one, has been actuated (signal sequence 0-1 active).
Reset (if present) always has priority over Reset2. Reset initialises
the application; only then is Reset2 accepted.
EDM1 (Out1)
An external device monitoring connected to the release module
reports the contactor's dropout (logical 1 present).
EDM2 (Out2)
An additional external device monitoring connected to the release
module reports the contactor's dropout (logical 1 present).
Application B
An output of application B connected to the release module
outputs logical 1 (application B is not deactivated).
If the input associated with Application B’s output is logical 0,
then Applications A’s outputs Out1 and Out2 switch off.
Logic
A logic module connected to the release module outputs logical 1.
Take into account the possible Logic signals when using Standard-, Release and PSDI
Function Blocks
Unused Inputs will be seen as a Logical 1. The outputs Out1 and Out2 can be thereby
active. Take this into account in your application.
