Overview
The 6ES7517-3AP00-0AB0 is a Siemens SIMATIC S7-1500 CPU 1517-3 PN/DP, a mid-range controller with Dns enabled and a single PROFINET port. It supports MRP (MRP Automanager per IEC 62439-2 Edition 2.0, MRP Manager, MRP Client), Modbus TCP, and an RS-485 interface on X3, making it suited for mixed-protocol plant networks.
Function & operation
The CPU 1517-3 PN/DP runs the user program with a 32 kbyte input process image and 32 kbyte output process image, handling all I/O within the process image for deterministic scan cycles. The single PROFINET port operates at 100 Mbps and supports MRP for media redundancy, MRP Automanager according to IEC 62439-2 Edition 2.0, and MRP Client roles — critical for ring topologies where a single cable break must not drop the network. On-board Modbus TCP and RS-485 (X3) provide direct connectivity to legacy serial drives, meters, and Modbus devices without an external gateway. The controller also supports CFC, DCP, DHCP, LLDP, SNMP, HTTP/HTTPS (standard and user pages), and optional encryption — a full suite for plant-wide integration and remote diagnostics.
Integration & mounting
A maximum of 8 communication modules (CMs/CPs) for PROFIBUS, PROFINET, or Ethernet can be inserted in total. The module size is 16 kbyte, and the key count is 6.
Lifecycle & compliance
The 6ES7517-3AP00-0AB0 carries a RoHS compliance date of 21-07-14, confirming it meets the EU RoHS directive as of that date. No end-of-life or phase-out notice is recorded in the evidence; the part is assumed active in Siemens' current portfolio. For the most current lifecycle status and any PCN notifications, a firm RFQ will confirm availability.
