Product details

What this CPU is built for

The 6AG1516-3AN02-7AB0: It integrates a PROFINET IO controller with MRP redundancy manager/client support, allowing ring topologies of up to 50 devices. That means a single ring failure won't drop communications. Process image is 32 kbyte each for inputs and outputs — enough for a mid-sized machine cell or a small process skid. All programming languages are onboard: LAD, FBD, SCL, STL, GRAPH, plus PID controllers for temperature and valve control.

The -40 to 70 °C range is exclusive to this SIPLUS variant.

Panel-fit notes

Dimensions are 105 x 147 x 129 mm (W x H x D).

Frequently asked questions

Will 6AG1516-3AN02-7AB0 drop into a panel originally built for 6ES7515-2AN03-0AB0?

Yes, it is the same footprint and uses the same wiring. The physical dimensions (105 x 147 x 129 mm) are identical to the standard S7-1500 form factor, and the backplane bus is compatible. The only change is the extended temperature range and conformal coating.

What are the key environmental ratings?

Operating temperature -40 to 70 °C, which is the headline difference from standard S7-1500 CPUs. No derating needed within that range.

What protocols does the integrated Ethernet port support?

It supports TCP/IP, UDP, MODBUS TCP, HTTP/HTTPS (standard and user pages), SNMP, and LLDP. PROFINET RT with MRP is standard.
