Product details

Software controller integration brief

The Siemens 6AG1677-2DB42-2GB0 is a SIMATIC S7-1500 Software Controller CPU 1505SP. It runs on a standard industrial PC or embedded system, providing full S7-1500 logic without a hardware PLC rack. The controller supports PROFINET IRT, MODBUS TCP, RS485, and IEC programming languages (LAD, FBD, STL, SCL, GRAPH). The ambient temperature range sits at -40 to 70°C, handling extreme environments. The process image manages 32 kbyte inputs and 32 kbyte outputs. Note that CFC (Continuous Function Chart) is not supported.

Sourcing and fit check

No official lifecycle status has been published, so confirm lead time at time of order. The I2t rating of 0.426 A²·s with starting current inrush should be factored into power supply fuse coordination.

Frequently asked questions

What does the CFC field mean on this controller?

CFC (Continuous Function Chart) is not supported on the 6AG1677-2DB42-2GB0. Toolchains relying on CFC, typically for drive or process control, cannot be used directly on this software controller.

What protocols are supported?

The controller supports PROFINET IRT, MRP, MRPD, UDP, TCP/IP, MODBUS TCP, RS485, HTTP, HTTPS via Windows and PROFINET interface, DCP, LLDP, and SNMP.

Can the 6AG1677 replace a 6AG1513-1AL01-7AB0 in an existing panel?

No. The 6AG1677 is a software controller that runs on a PC; the 6AG1513-1AL01-7AB0 is a hardware CPU that mounts in an S7-1500 rack. Physical mounting, wiring, and software architecture differ. A panel reengineering would be required.
