Vertical Lift - Kardex

This module extends the existing vertical lift functionality so that Odoo can talk to Kardex Remstar vertical storage machines.

• On a vertical lift shuttle, a new hardware option "Kardex" becomes available in the hardware selection. When a location's shuttle uses this hardware, Odoo builds Kardex-specific messages instead of the generic ones.
• When a user fetches a tray (for a pick, put or inventory operation), Odoo sends a command to the machine with the shuttle code, a sequence number, the tray address, the tray level and, if a specific cell is targeted, the cell's X/Y position inside the tray. The command code depends on the operation: pick, put or inventory.
• When a tray is released (closed), a release command is sent with the tray address and empty carrier information.
• Before sending a fetch command, the module checks that the tray has a level configured and, when a cell is targeted, that the cell has a valid position. If not, the user gets a clear error message asking to fix the configuration or the tray type dimensions.
• Responses coming back from the Kardex machine are interpreted: success codes, interface errors, machine-busy or timeout situations, queued or active requests, and various machine error ranges are translated into readable error messages stored on the command.
• A separate proxy program is provided to relay messages between Odoo and the Kardex server, keeping the connection alive and forwarding machine answers back to Odoo.

The module touches stock.location and vertical.lift.shuttle.
