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.

Cards and card formats

Card formats defined on the host download to the station and appear in Enterprise Security as Wiegand formats named Z9 Open .... A card downloads as one badge per card format it can encode into; a format that carries its own facility code applies that facility to cards that do not specify one. Badges created by the module carry a z9flex:cred=... description marker.

Door status: forced and held

Door forced and door held (open too long) are taken from Enterprise Security's own alarm extensions on the door's contact, so what the host reports always matches what the station itself alarms on -- including request-to-exit masking and the station's configured held time.

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).
