Diverse range of field bus interfaces

ProfiSignal software offers a diverse range of field bus interfaces. A master device is equipped with two PROFIBUS DP salve interfaces (redundant according to PNO 2.212 V1.2), a Modbus TCP and a Modbus RTU, as well as a freely configurable CAN interface. The interfaces can also be used to connect serial measurement equipment via RS232/485 ports.

 

Connecting ProfiMessage to a PC or server takes place via a high speed Ethernet connection. X-Message functions enable ProfiMessage devices to communicate without PC support and to exchange measurement data and alarm information.

PROFIBUS (redundant)

ProfiMessage also has two optional and separate PROFIBUS DP slave interfaces. ProfiMessage is integrated into PROFIBUS via a GSD file. Any analog or digital signal can then be read or written to from PROFIBUS. There is the option to switch operating mode to redundant (according to PNO 2.212 V1.2) PROFIBUS.

Modbus TCP/ RTU

The LAN and RS485 interface can also exchange data via the Modbus TCP/RTU protocol. ProfiMessage support this operation as a Modbus master or slave.

RS232 / RS485

These serial interfaces can function with separate protocols. Protocols can be created either directly by the user or by Delphin. Applications include the control of climate chambers, laboratory devices, power measuring units or GPS reception.

CAN bus

The CAN bus interface can be programmed according to user requirements. The CAN bus can read, scale, process and record any identifier.

LAN / TCP

The LAN interface transmits online all measurement data, including software channels, at high speed across the intranet or internet. Any networked PC can access ProfiMessage via this interface. Other TCP services are available such as NTP, FTP, HTTP and SFPMP etc.. The internal data memory can also be read out via the LAN.

USB interface

The USB interface (master) can be used to read out the internal data memory to a USB data stick.

Expansion bus

The expansion bus enables up to 20 slave devices to be connected to the master device.
