Smart networking: Robots and peripherals in perfect harmony 

This is how IntelliAgent connects mobile robots and peripheral devices, ensuring a seamless workflow.

Our mobile robots are networked via Wi-Fi using the IntelliAgent software and communicate both with each other and with peripheral systems. These typically include elevators, lift tables, fire protection doors, transfer stations, and conveyor technology. Peripheral systems are integrated into our system via interfaces and can interact with the swarm. Just like with the vehicles, key information can be retrieved and exchanged. The result is seamless interaction between various devices and systems. This ensures that a mobile robot is not blocked by a closed door and that elevators are always available at the right time.

Exchange of information via communication protocols

The connection can be established traditionally via a PLC, which is often used to control robotic systems. PLC integrations are possible, for example, via OPC UA or Modbus. While Modbus is a simple and open protocol that is easy to implement, OPC UA is more advanced. It enables enhanced services such as data modeling, increased security, and real-time communication. This allows for standardized access to machines, devices, and other systems. If no PLC is available, peripheral devices can also be connected via a SAFELOG XS controller. On one hand, it offers potential-free contacts and the ability to connect peripherals via the industrial ASi bus. On the other hand, it can be accessed via Ethernet through the IntelliAgent network.  Good to know: Potential-free contacts can transmit yes-no statements, and this works for any electrical system. For example, it can be used to check whether a fire protection door is open or closed or whether a vehicle is in the elevator or not. 

Three degrees of freedom for optimal integration

Connections to peripheral systems can be realized in three different ways within an IntelliAgent system: 

1. Establish a connection ad hoc: Each AGV connects directly to the peripheral system according to the communication protocol and transmits the relevant information directly.
2. Connection via a SAFELOG terminal: The IntelliAgent on the terminal reads and writes information on behalf of the swarm. The mobile robots communicate only indirectly with the peripheral system.
3. Control connection via SAFELOG Flow Control: Data exchange and control of peripheral devices from a central network infrastructure. The software acts as the central control station.
