Part No.: MPHS-COMX-100CA-RE+C(+Controller)

PROFINET IO-Controller/ Device: The module for all communication tasks



  • Universal master / slave interface with network connector onboard
  • Host connection via dual-port memory
  • One hardware for all Real-Time Ethernet protocols
  • Allows one baseboard design for all networks

Product Description

The comX communication module has been designed to be integrated into automation devices e.g. robot controllers, PLCs or drives to add a network interface. All communication tasks are executed autonomously within the module - irrespective of the processor of the target device.

Process data is exchanged via a Dual-Port-Memory which is accessed either by an 8-/16-bit bus interface or a fast 50 MHz SPI interface.

comX supports all major Real-Time Ethernet protocols as Master or Slave and covers all network-specific demands in just one single module. To support a line topology, the module is equipped with two Ethernet ports. The communication protocol can be changed simply and reliably by loading the appropriate firmware and a software license for masters.
