Remote access with Profibus

July 2018

Global technology powerhouse Siemens is extending its portfolio of industrial routers with the Scalance M804PB, a device which allows existing machines and plants to be connected to Ethernet networks via Profibus/MPI (multi-point interface).

Users can also economically connect older machines and plants directly to the Sinema Remote Connect management platform for remote networks, the company said in a statement. Secured communication takes place via a VPN tunnel which can be easily configured and administered via Sinema Remote Connect, it added.

The Scalance M804PB extends the proven Scalance router product line and provides a consistent remote maintenance concept for existing and new plants making it suitable for companies in the manufacturing industry such as mechanical equipment manufacturers (original equipment manufacturers / OEMs) as well as for companies in the automotive, food and beverage, chemical and pharmaceutical industries.

The device has integrated TIA Portal cloud connector functionality, which allows users to easily access existing Profibus units from centrally administered engineering tools such as the TIA Portal or Step 7 (from version 5.5). The Scalance M804PB is a Profibus/MPI router for private, wired networks even with existing two-wire cabling. In addition to a Profibus/MPI connection, it also has two RJ45 interfaces in the form of a fast Ethernet two-port switch. It also has a C-Plug/Key-Plug slot.

The new router supports VLAN, Firewall/VPN (IPsec)/NAT, OpenVPN (as client), VRRP/RSTP and can be configured for CLI and SNMP via web-based management tools. Download and upload data rates of 9.6 Kbit/s to 12 Mbit/s can be achieved on the Profibus/MPI interface. The redundant supply voltage is DC 24 V. Mounting options include wall mounting, DIN rails and S7-300 or S7-1500 profile rails.

The Scalance M804PB Profibus/MPI router has the same user interface and comparable performance characteristics as the Scalance M-800 and S615 product line as it is based on the same firmware. This provides easy handling and compatibility with existing systems (for example, the Simatic portfolio, network management software etc.). For example, with the Scalance M804PB, digital input and output allow on-site access control via key switches, the company said.
