Modula Link is theWMS系统to provide an external Host System with low-level control of a group of Lift OS machines, using a set of commands communicated over a TCP/IP sockets channel.
Modula Link acts as thecommunications server: it opens a TCP port (configurable) and waits to receive commands; when it receives a valid command from the external host system, it processes it and responds.
Modula Link can be configured to handle commands from a single client (mono-client communication) or from several clients (multi-client communication).
When the host system needs to call a tray, it uses the appropriate command. The moment the tray is ready in the bay, Modula informs the ERP, which proceeds with the operation and sends a command on completion to return the tray to its location.
TheModula Link WMS systemreceives only one call tray request, the console shows the tray is ready, but does not notify the operator; the ERP notifies the operator of the activities to be carried out and asks for confirmation of the action.
Typically, the picking tool used is an RF terminal, less often an external PC. With precise, real-time control of the warehouse, the ERP can be equipped with a series of advanced logistics features.
