Product details

Ruggedized S7-1500 for the Harsh Spots

For motion on PROFINET, IRT is baked in. MRP handles ring redundancy—up to 50 devices in the ring. MODBUS TCP rides the same port, and an RS485 interface is onboard for legacy drops. S7 routing is enabled, so you can reach across networks without an extra gateway.

What Connects and How It Mounts

DIN rail mount, 70 mm wide × 147 mm tall × 129 mm deep. Up to eight communication modules (PROFINET + PROFIBUS) fit on the side. RS485 is built in; DHCP comes switched off by default. LLDP and SNMP are ready for network discovery and management. HTTP and HTTPS both serve standard and user-defined pages—good for custom dashboards or recipe upload.

Sourcing Reality: Not a Standard Shelf Part

Rated -40 to 70 °C. controller with integrated optimization for valves is supported.

Frequently asked questions

Can this CPU operate in freezing temperatures or high humidity?

Yes. The SIPLUS coating and -40 to 70 °C range are designed for condensation, freezing start-ups, and high-humidity cabinets. It is not just a temperature extension—the conformal coating protects against corrosion.

What communication protocols are supported natively without an extra module?

Onboard: PROFINET (with IRT), MRP client/manager, MODBUS TCP, UDP, TCP/IP, RS485, LLDP, SNMP, HTTP/HTTPS web server. PROFIBUS needs a CM module.

Is there a standard S7-1500 version that shares the same form factor?

The closest standard version is the 6ES7516-3AN00-0AB0, but that lacks the SIPLUS coating and extended temperature range. Physical dimensions match (70×147×129 mm), so panel cutouts are compatible, but environment ratings differ significantly.
