Description

Network Compatible and Modular

Delphin ProfiMessage data acquisition systems are modular devices for data acquisition and automation. A master/slave design makes ProfiMessage suitable for both small and large applications that require the processing of thousands of channels. Master and slave devices can each accommodate two I/O modules. There is a range of I/O modules for users to select an appropriate module(s) for their application. I/O modules are available for any number of channels and sensor types. A network interface enables ProfiMessage devices to be integrated into a TCP network or to be directly connected to a PC workstation or laptop computer. Online measurement data can be transmitted, saved and processed. The data can be stored simultaneously within the ProfiMessage device itself.

ProfiLab is identical in construction and functionality to ProfiMessage – only their housings differ. ProfiMessage devices are designed for rail-mounted installations, and ProfiLab, with its 4 mm plugs, for laboratory applications.

Universal Connectivity

ProfiMessage’s universal inputs enable the connection of signals of any type including non-isolated signals. This means costly measurement transducers are usually not necessary. Potential isolation between channels as well as differential inputs saves both time and money.

Universal inputs enable any unit of measurement to be acquired (e.g. temperature, pressure flow, vibration etc.). Data then undergoes direct scaling and linearization. Conversions from mA to bar or ml/min take place directly within the ProfiMessage device. High measurement precision is achieved though the use of 24-bit resolution Sigma Delta converters and enables the connection of the smallest of signals (e.g. thermocouples).

Various Applications

  • Multi-channel data acquisition
  • Monitoring and alarm management
  • Test stand automation
  • Product testing
  • Quality assurance
  • Monitoring of buildings

Easy to configure

An optional integrated data memory can permanently store up to 128 million measurement values without PC-support and with edge or level triggering. The ProfiSignal-Software enables online / offline analysis, visualization and operation from any PC workstation as well as PC-controlled process automation and database communications via ODBC/SQL.

Configuration of the Message devices takes place with the PC user-friendly DataService / Configurator software. Configuration data is processed online and permanently within the devices. Configuration data may be amended and adjusted during measurement runs.

Mobile Energy Measurement Case

These cases feature an integrated 3-phase power measuring unit for measuring the electrical power from motors, pumps, drives etc. Energy data from PLC or control systems can also be acquired via field bus interfaces such as PROFIBUS or ModBus. The energy measurement case is configured via LAN and can then function independently thanks to its integrated data memory capable of storing several million measurement values. The case can also be equipped with a UMTS modem to enable wireless operation for remote monitoring applications. Cases are now available.

Modules

Master and Slaves

The ProfiMessage series has 2 types of devices: masters and slaves. The master device contains the CPU unit and data storage capability. Salve devices serve as extensions to the master device. Each device can be equipped with 1 or 2 I/O modules.

The ProfiMessage master is connected via standard cabling with a TCP/IP network. Slave devices are connected to the master via a CAN bus. Any number of master devices can be connected into a network. A maximum of 1000 I/O channels can be processed within a master-slave system.

Modular design

Each device (master or slave) can accommodate 2 different input/output modules. There are no restrictions in to which slots the modules are inserted. Sensors are connected via detachable clamps. For servicing, the rows of clamps can easily be removed by undoing 2 screws without having to disconnect any cabling.

Necessary steps for project planning:

  • Create a list of analog and digital channels
  • Allocate channels to modules
  • Allocate modules to master and slave devices

Standard module measuring rate

Even with large numbers of channels the measuring rate is not affected by the number of input/output modules, with a maximum rate of 600Hz for standard modules. Each module is equipped with an A/D converter. A multiplexer consecutively connects each separate measurement channel.

Very precise measurement accuracy; resolution 24 bit; Autocalibration.

AMDT module features

  • 8 channels for vibration and dynamic measuring
  • ADFT for dynamic measuring in time domain signals
  • AMDT/V for frequency and time domain signals. Simultaneous calculation of characteristic values

Interfaces

Connecting to the PC world via Ethernet

ProfiMessage devices can be easily connected up to existing data networks. Large quantities of data can be transferred and accessed via PCs.

The ProfiMessage master device (see illustration) is connected to the Ethernet using standard cabling. Practically any number of master devices can exist within a data network.

ProfiMessage devices support current network functions:

  • static IP addresses
  • DHCP (Dynamic Host Name)
  • FTP (reading data storage)
  • http (internal web pages)
  • SNTP (time synchronization)
  • SMTP (sending emails)

Connecting slaves via CAN-Bus

The ProfiMessage master can be extended using slave devices. Slaves are connected to the master via a CAN bus.
The CAN (Controller Area Network) is a serial bus system with good transfer properties over short distances. Its main benefits are its high levels of reliability and a set maximum waiting time for high priority messages. The CAN bus is therefore capable of real time processing. It has a transfer rate of 1Mbit/s (adjustable for long cable lines).

Connecting external devices via RS232/485 ports

The ProfiMessage device is equipped with four independent serial ports which can be used for both the connecting up to PC software (bus manager) or external devices. They can be used for importing data (from weighing machines) or exporting data (display systems). Data exchange is configured via COMPORT (channels). The required interface parameters for the corresponding mode can be configured here. Industry standard protocols are also available such as Modbus RTU, Profibus DP Slave (optional) and Modbus LAN.

Connecting a PLC via Profibus interface

A serial port can also be utilized as a Profibus DP slave port.
The ProfiMessage device can then read and write signals from a PLC device. At the same time values can be transmitted to the PLC – a 2-way link exists between the PLC and TopMessage device.

Connecting to a modem via the RS232 port

The RS232 port is intended as a modem link. Measurement data stored in the TopMessage data logger can be transmitted at predetermined time intervals.

Data transmission via telephone and radio telecommunications

ProfiMessage does not differentiate between data networks and external data transmission. This means all functions available for network processing are also available for external data transmission.
Because data can be stored locally within a Message device, uninterrupted data transmission to a central server, at low telephone costs, can be performed without the need for any PC support. Using the internet can further reduce costs. In the event of a malfunction an immediate warning is issued with the automatic sending by email of fault messages and fault occurrences.

Event log with pre and post history

Events and scenarios can be configured into the system. Malfunction messages can be allocated to these events with data and pre and post history being saved. Switch outputs can also be set enabling the production of warnings and alarms.
In network environments emails can also be issued.

Vibration

Made possible by state-of-the-art DSP technology

The AMDT/V module in the ProfiMessage system provides vibration analysis and monitoring in one system. ProfiMessage’s modular system enables the simultaneous monitoring of both machine vibration and process values such as temperature and pressure.
