Siemens is extending its portfolio of industrial routers with the Scalance M804PB. This device allows existing machines and plants (for example with Simatic S7-300/S7-400) to be connected to Ethernet networks via Profibus/MPI (Multi-Point Interface).
The device has integrated TIA Portal cloud connector functionality. This 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 Scalance M804PB 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.
