Simplify your connections using CompactCom Modbus Serial Interface

The CompactCom 40 Modbus Serial network communication module is an easy to use low cost communication solution for simple industrial field devices. The product combines the simplicity of the Modbus Serial protocol with the flexibility of the Anybus NP40 technology. It is perfect for applications like basic level I/O blocks, temperature controllers, measuring devices, sensors and other devices where size, implementation effort and time is an issue.

The CompactCom 40 Modbus Serial software interface is designed to be network protocol independent, making it possible to support several networking systems using the same application software code/driver. The host communication is based on Modbus RTU, a proven protocol which is easy to implement yet flexible enough to provide room for future expansion.

Features and benefits

  • Simple implementation and great connectivity flexibility
  • Serial Communications Interface (UART-interface)
  • Standard Modbus RTU serial protocol 
  • Galvanic isolation integrated for a safe and simple in-design
  • Low power consumption
  • Precertified technology makes certification a nonissue
  • Short in-design with free technical support from HMS ensures a fast time to market

Anybus CompactCom B40 Modbus Serial Interface - Modbus TCP

The CompactCom B40 Modbus Serial for Modbus TCP enable simple communication between your device and the Modbus TCP network.

ADD YOUR OWN CONNECTORS AND PERIPHERALS
The CompactCom B40 Brick gives you the flexibility to add your own connectors and network isolation. An alternative is to use the ready-made connector board from HMS. The B40 Brick is ideal for device manufacturers who are looking for a semi-integrated solution where connector flexibility, size and cost are key elements.

ONE IN-DESIGN – ACCESS ALL NETWORKS
By implementing the CompactCom B40 Brick into your product line, you can get connected to other B40 supported networks simply by switching to another CompactCom B40 Brick.

GET REAL-TIME MODBUS TCP COMMUNICATION

The B40 Brick enables communication between your device and Modbus TCP. The Brick supports generic device profiles and comes with a dual port switch implemented in the network processor — the award-winning Anybus NP40.
