Z9OpenService

The Z9OpenService is the bridge between this station's Enterprise Security data model and a Z9/Flex host. Place one instance under the station's Services. Once the station is taken over by a host, the service maintains the connection and keeps the two sides in sync; no per-object configuration is needed on the station side.

What syncs in which direction

• Uploaded to the host (the station is the authority): the access-control doors and their remote modules, door hardware configuration (default access mode, strike time, re-lock), door status (online, locked/unlocked, open/closed, forced, held), and access/door events.
• Downloaded from the host (the host is the authority): people and cards, schedules and holidays, access rights, card formats, and door commands (unlock, access mode changes, lockdown). Downloaded objects appear in Enterprise Security as regular records.

Actions

• Factory Reset -- clears the host pairing so a different host can take the station over. The station's Enterprise Security data is not touched.
• Log Niagara Data -- writes a read-only snapshot of the station's access-control records to the station log (under z9open.probe), useful when troubleshooting synchronization.

Troubleshooting

The module logs under z9open.* in the station log; synchronization messages show what was received and applied. If a downloaded object does not appear in Enterprise Security, the station log states the reason (for example, a card whose number or facility code does not fit any downloaded card format).
