Features:
- PLC execution and integrated technology functions share one CPU 317T-3 PN/DP.
- Dedicated interfaces separate general MPI/DP traffic, drive PROFIBUS, and PROFINET.
- Four technology inputs and eight high-speed outputs connect time-critical field signals directly.
Siemens 6ES7317-7TK10-0AB0 combines controller memory, technology processing, and communication resources in one S7-300 module.
The drive DP master has a narrower role than the first MPI/DP port, while the Ethernet interface adds PROFINET controller, device, and open communication services.
Project storage depends on the required Micro Memory Card, and online commissioning uses STEP 7 with the S7-Technology package.
The Siemens 6ES7317-7TK10-0AB0 SIMATIC S7-300 CPU 317T-3 PN/DP Technology CPU may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Direct signal paths for coordinated functions
- Fast inputs: Four 24 V DC digital inputs feed the integrated technology functions.
- Fast outputs: Eight 24 V DC outputs provide the high-speed switching path used by functions such as cam signals.
- Field isolation: The input and output circuits are isolated from the backplane bus.
- Shared processor: Technology events and the standard PLC program execute inside the same CPU.
Why the three communication paths are not interchangeable
- MPI/DP port: The first RS 485 interface supports programming, operator, routing, and general PROFIBUS DP services.
- Drive port: The second RS 485 interface operates as the dedicated PROFIBUS DP drive master and omits PG/OP routing.
- Ethernet pair: Two switched RJ45 ports form the physical PROFINET connection.
- Open communication: TCP/IP, ISO-on-TCP, and UDP services use the integrated Ethernet interface with supported blocks.
Choosing one isochronous process domain
- DP option: OB 61 can synchronize a supported PROFIBUS DP process.
- PROFINET option: The same isochronous task can instead use PROFINET IO.
- Selection rule: PROFIBUS DP and PROFINET IO cannot provide isochronous mode simultaneously.
- Time source: The CPU can synchronize by MPI, DP, automation-system time, or Ethernet NTP according to the configured role.
How the engineering project reaches retained memory
- Required card: The CPU requires an 8 MB Micro Memory Card for load memory.
- Work area: The integrated 1 MB work memory holds the executing program and process data.
- Engineering tools: STEP 7 V5.5 SP2 or higher works with S7-Technology V4.2 SP3.
- Commissioning evidence: Online status, forcing, service data, and the diagnostic buffer support project verification.
