For security reasons, all switching commands are signed and given a time stamp in the Access system. The time deviation between Access end devices and the Access Server must be no more than 59 seconds. Siedle hardware end devices with impermissible time deviations from the Access Server do not execute any switching commands. Note: Please only use one time server/time server pool with one address for the Access system.
