Parameter overview
PrmName Meaning
Standard outputs In addition the output can be switched off from the standard PLC. The safe
active output is linked with the standard logic signal AND.
Current Current measurement for the outputs is activated
measurement
active
Testing of outputs Test pulses for the outputs are activated
active
Error acknowledge True:
active
Terminal errors lead to a reset of the TwinSAFE connection (error code 14
(0x0E)). This error code is shown in the diagnostic data for the connection
until the user acknowledges it via ErrAck in the TwinSAFE group.
False (Default):
Terminal errors can only be reset by switching the power supply off and back
on again.
Store Code This parameter is required for the TwinSAFE Restore Mode
Project CRC This parameter is required for the TwinSAFE Restore Mode
Test pulses
If the parameters Current Measurement active or Testing of outputs active are set to TRUE, the ter-
minal generates test pulses at the outputs.
To avoid generating test pulses at the channel outputs, Testing of outputs active and Current mea-
surement active must be set to FALSE.
Please note that deactivating of Current measurement active and/or Testing of outputs active may
reduce the achievable performance level.
A calculation example for the performance level can be found in the TwinSAFE application manual.
There are no known application for which it would make sense to set Testing of outputs active to
FALSE, while Current measurement active is set to TRUE.
