Q1: Is the 6ES7317-2EK14-0AB0 still in production?
Yes. This product has lifecycle status PM300 (Active Product) and is still in standard production. It remains available for new designs and replacements.
Q2: What software is required to configure this CPU?
The CPU is configured using STEP 7 V5.5 or higher. It is also supported in TIA Portal (STEP 7 Professional) for programming and configuration.
Q3: What is the difference between this CPU and the earlier version 6ES7317-2EK13-0AB0?
The -2EK14-0AB0 is the successor to the -2EK13-0AB0 version. The newer version offers improved performance and enhanced PROFINET functionality. The official release in February 2010 marked a significant upgrade with faster processing speeds (25 ns bit operations) and increased memory.
Q4: What is the 1 MB work memory equivalent to in S7-1500 terms?
Not directly equivalent. S7-300 uses unified work memory (program + data combined), while S7-1500 separates these into distinct program and data memory allocations. For practical purposes, the 317-2 PN/DP's 1 MB capacity corresponds approximately to the CPU 1510SP-1 PN (200 KB program + 1 MB data).
Q5: Is a Micro Memory Card (MMC) required for this CPU?
Yes. The CPU requires a Micro Memory Card for program and data storage. The MMC serves as both load memory and retentive memory, ensuring data retention without battery backup.
