Product details

Software controller with extended temperature range

The 6AG1677-2AA31-4EB0 is the S7-1500 Software Controller CPU 1505SP V2.0, a PC-based PLC variant that runs the control logic on an embedded Windows or RTOS platform. It communicates over PROFINET IRT, supports MRP and MRPD for media redundancy, and includes MODBUS TCP, RS485, and UDP. The hardware clock keeps time across power cycles, and the 32 kB process image covers all I/O in the backplane.

What the missing features mean for your design

Two omissions are critical to catch before locking the BOM line. CFC (Continuous Function Chart) is not supported, so any existing CFC application libraries cannot be migrated directly; you will need to convert the logic to LAD, FBD, or SCL or select a CPU that includes CFC. PROFIsafe is also absent—this CPU handles only standard control, not safety-related functions. If your machine requires integrated safety with PROFIsafe over PROFINET, you need a separate F-CPU or safety-capable ET 200SP modules. All standard communication interfaces (IRT, MRP, MODBUS TCP, RS485) are present as listed.

Frequently asked questions

Does this CPU support CFC programming?

No. CFC (Continuous Function Chart) is listed as not supported. Use LAD, FBD, SCL, or STL instead.

Does it support PROFIsafe?

No. PROFIsafe is not supported on this CPU. Safety control requires a separate F-CPU or safety modules.

What protocols are available?

The 6AG1677-2AA31-4EB0 supports PROFINET IRT, MRP, MRPD, MODBUS TCP, RS485, UDP, HTTP/HTTPS (via PROFINET), SNMP, and LLDP. It also includes a hardware clock.

What is the ambient temperature rating?

Operating ambient range is -40°C to 70°C.
