The sequence of communication between the Nucleo blocker and Rx-Universe is:
1) Rx-Universe will select the block base/diameter to use and print it on the work ticket.
2) The operator either selects blocks and places them in the tray, or the Nucleo will select blocks from the internal carousel.
3) The Nucleo requests job information from Rx-Universe using a standard VCA request.
4) The Nucleo scans the barcode on the block, and sends the block ID to Rx-Universe using LDCS, command 1100. Rx-Universe responds with data on the block, if it has been previously used, or with an identifier that this is a new block. It also sets the _BLKRU label to "1" if the block can be re-used, or "0" if it cannot be re-used. If the block cannot be re-used, the appropriate message is displayed on the blocker.
5) If the block is usable, the blocker then sends an LDCS command 1101, which identifies the job and eye being used for the blockpieceblock piece, allowing Rx-Universe to link the blockpiece block piece to the job.
56) After blocking, the blocker sends information on the combined block and blank to Rx-Universe using standard VCA protocol.
Once blocked, the job will be generated; again, there are two communication sessions that take place between the generator and Rx-Universe; the standard device information is sent using VCA, and the blockpiece block piece information needed for the re-use function is sent via LDCS.
...
After surfacing, if the block is removed using an automatic Nucleo de-blocker, the de-blocker will communicate with Rx-Universe using LDCS, to obtain the blockpiece block piece information for the job being scanned, including _BLKRU indicating whether each block can be re-used or should be discarded.
...
Under "Setup", "System Settings", on the "DevicesBlocking" tab, the port number to be used for LDCS and , the maximum number of times a Nucleo block or ART block can be re-used , must each be set. The default values are shown below:
Then, each of the re-use devices (blocker, generator, and de-blocker) must be set up with an LDCS interface in addition to the normal VCA interface.
...
As an example, consider devices set up with the following IP addresses:
Rx-Universe Server - 192.168.168.1
Nucleo blocker blocker - 192.168.168.100
Orbit Generator Generator - 192.168.168.120
De-Blocker - 192.168.168.122
LDCS connections will use port 33520.
In Rx-Universe, 5 device sessions would be set up - 2 VCA connections for the Nucleo and Orbit, and 3 LDCS sessions, one for each of the blocker, generator and de-blocker, as follows:
...
The de-blocker requires just an LDCS session for the re-use functionality, so only one session is needed for it:
With the device sessions set up, just make sure both the T1 and L1 device sessions are running on the device server (in this case, the computer with IP 192.168.168.1).
...
Then, in the interface setup screen, specify the reUse server protocol, the IP address of the Rx-Universe server, and the LDCS port number::
Re-Use Blocks in Rx-Universe
The data on the individual block pieces can be viewed in Rx-Universe, using the "Re-use blocks" option on the "Device" menu.
Blocks can be looked up using either the Block Piece ID, or by JOB ID.
For each block piece, the following information is available to be viewed:
The Manufacturer code determines if a block is an ART Premium block. When the first digit of the manufacturer is a "1", this is considered a Premium block. All other blocks will be considered as regular blocks when determining the usage.
The BLKDM1 and BLKDM2 fields are the diameter of the block, after cribbing, as reported by the generator. If the two values are different, the block is elliptically-shaped, and the "Elliptical axis" field would indicate the axis of the ellipse.
The only fields that can be changed are the BIN, the BLKSH, and the number of times the block has been used.
