TopMessage - Data interface

TopMessage devices can be easily connected up to existing data networks. Large quantities of data can be transferred and accessed via PCs.
The TopMessage master device (see illustration) is connected to the Ethernet using standard cabling. Practically any number of master devices can exist within a data network.
TopMessage 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 TopMessage 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 TopMessage device is equipped with two 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 TopMessage 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
TopMessage 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.
