Transport Command#

The task Transport Command is a Task that performs fleet management (AGV) through the message bus. It supports several fleet managing platforms and commands and has three different operation modes:

  • Requester
    • Sends a command request (to a "Receiver"), typically to other tasks of fleet managing related workflows (that have the specific vendor drivers), waits for and handles the reply.
  • Receiver
    • Receives commands (typically from factory automation workflows) and relays the data to the fleet managing driver
  • Replier
    • Receives data from the fleet managing driver and sends the reply to the "Requester"
