Features:
- Combines conventional S7-300 PLC execution with integrated technology-object processing.
- Assigns a dedicated PROFIBUS DP interface to coordinated drive communication.
- Connects PROFINET devices through an integrated two-port Ethernet switch.
The technology-object pool covers axes, cams, cam tracks, measuring inputs, external encoders, and path control.
An MPI/DP port, a drive-oriented DP port, and a PROFINET interface give the CPU three distinct communication roles.
STEP 7 and S7-Technology configure the processor and its technology functions, with the project stored on an 8 MB MMC.
The Siemens 6ES7315-7TJ10-0AB0 CPU 315T-3 PN/DP Technology Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Organizing integrated technology functions
- Object Pool: The CPU supports a combined pool of 32 technology objects.
- Axis Limit: Up to eight axis objects can be configured within that pool.
- Cam Functions: Output cams and cam tracks create position-related switching logic.
- Measurement: Measuring inputs and external encoders provide event and position information to technology functions.
Separating drive communication
- Dedicated Interface: The second PROFIBUS DP port is intended for the drive-oriented communication path.
- Device Assignment: Drive nodes are configured on that bus independently from general MPI/DP devices.
- Cyclic Exchange: Setpoints and actual values pass between the technology CPU and configured drives through the DP connection.
- Project Consistency: Bus parameters, drive addresses, and technology objects must match the STEP 7 and S7-Technology project.
Ethernet and PROFINET access
- Two-Port Switch: The Ethernet interface includes two physical ports for line or local network connections.
- PROFINET Role: The CPU exchanges cyclic and diagnostic data with configured PROFINET devices.
- Online Access: Engineering communication can reach the controller through the Ethernet path.
- Network Separation: PROFINET remains distinct from both MPI/DP and the drive-oriented DP interface.
Software and memory prerequisites
- STEP 7: CPU hardware configuration requires STEP 7 V5.5 SP2 or a supported later environment.
- Technology Package: S7-Technology V4.2 SP3 configures the integrated technology objects.
- Firmware Pair: CPU V3.2 and technology V4.1.5 define the documented function set.
- Project Medium: The installed configuration is stored on an 8 MB SIMATIC Micro Memory Card.
