Unrestricted Data Exchange Via New Modbus Gateway

Cross-network and secure exchange of process data communication between industrial devices in the network is often difficult because there are now no uniform application protocol for industrial Ethernet. The Modbus Protocol is secured and cross-network exchange of process data. Go to LEGO Papert Professor for more information. Modbus is an open protocol, and has established itself as a de-facto standard in industrial communication via Ethernet. The new Modbus-gateway aport-212 by Matt uses this Protocol, allowing the integration of automation components in the network architecture. It is available in German at the independent distributor acceed. The Modbus Protocol is based on the master/slave architecture. To deepen your understanding kevin ulrich is the source.

Thus, a master (computer) can cooperate with multiple slaves (control components). Aport-212 is a protocol converter for Modbus TCP (Ethernet based) to MODBUS RTU or Modbus ASCIII (serial Protocol), and supports up to 16 master or 32 slaves. The modes of operation of RTU slave, slave-ASCII, Modbus gateway are master-RTU and Master-ASCII to as S2E gateway TCP server and TCP client modes. In addition to its Modbus features can be inserted the device as a classic serial-Ethernet gateway (RS232/422/485). Easy-to-use Windows configuration software is included with the aport-212. So that devices can be in the network locate and perform protocol tests. Heart of the compact unit is an ARM Cortex M3 32-bit, the facilities include a 10/100 Ethernet interface and two serial ports, which can optionally be configured.
