+===Controlling Event Triggering Behavior in TransSECS PLC applications===
+transsecs.ceidedgetrigger=true
+If this parameter is set to true events will be triggered only when the value changes from low to high (eg 0-1).  Changing from high to low is ignored.
+transsecs.resetceidtrigger=true
+If this is true, after the event is triggered, the value in the PLC (or other device) will be reset to zero.

+===Alarm Anti-Rebound===
+Two parameters prevent multiple set/clear alarms in a short period of time.  This will prevent multiple alarms being sent on, for example, a switch bobbling. Set the anti-rebound timeout to a value > 0 to enable this feature.
+<file>
+transsecs.alarmantirebounddeadband  (milliseconds)
+</file>
+For example, to prevent alarms within 0.5 seconds of the initial indication add:
+<file>
+transsecs.alarmantirebounddeadband=500
+</file>
+Note that adding an ECID AlarmAntiRebound_DeadBand can be used instead of the system property. If this ECID exists the value of transsecs.alarmantirebounddeadband configured in the ErgoTechConfiguration.properties file will be ignored.
+===Passive Host/Active Tool===
+This change should only be made under the direction of tech support and requires an addon package that contains the new configuration.
+<file>
+# Switch Active/Passive connections.  Hosts becomes passive, tools active.
+# All tools become active
+transsecs.passivewrapperclassname=com.ergotech.transsecs.secs.HSMSToolActiveWrapper
+# All hosts become passive (not required for a tool, but useful for testing).
+transsecs.activewrapperclass=com.ergotech.transsecs.secs.HSMSHostPassiveWrapper
+# The address of the host
+transsecs.activehostname=192.168.56.1
+# Optional. How often to wait between attempts to connect to the host in seconds
+# the default is 5
+transsecs.activeretryinterval=5
+</file>
+===HTTPS and Self-Signed Certificates===
+When TransSECS connects to an HTTPS endpoint that uses a self-signed certificate, Java must be configured to trust that certificate.
+See [[transsecs_trusting_self_signed_certificates|Trusting Self-Signed Certificates in TransSECS]] for instructions on exporting the server certificate, importing it into a Java keystore, and configuring the required trust store properties in ''ErgoTechConfiguration.properties''.
