Product details

CPU 1518-4 PN/DP – what it is

The Siemens 6ES7518-4AP00-3AB0 is a SIMATIC S7-1500 CPU 1518-4 PN/DP with a process image of 32 kbyte each for inputs and outputs, a 175 mm width (ten slot width), and an ambient temperature range of -40 to 70 °C. It supports LAD, FBD, SCL, STL, and GRAPH programming, and includes integrated PROFINET with MRP and MRPD (IRT is not present on this CPU, so MRPD cannot be used).

Mounting and communication

The CPU occupies one slot in an S7-1500 rack; dimensions are 175 mm wide, 147 mm high, and 129 mm deep. Network services include DCP and DNS for discovery and naming, MODBUS TCP, SNMP, HTTP/HTTPS with user pages, and LLDP.

Sourcing

Specify the 6ES7518-4AP00-3AB0 into your BOM as the controller for S7-1500 systems requiring a large process image and wide temperature range. Availability is quoted to order; submit an RFQ for current lead time.
