Application-Specific FAQ
Q: Is the 6ES7312-1AE13-0AB0 compatible with TIA Portal?
A: Yes. CPU 312 (AE13) is supported in TIA Portal V13 SP2 and later via the STEP 7 Professional add-on. Full programming is also available in STEP 7 V5.6.
Q: Can this CPU communicate with PROFIBUS DP slaves?
A: The base CPU 312 does not include an integrated PROFIBUS DP interface. Add a CP 342-5 communication processor (6GK7342-5DA02-0XE0) to the rack for PROFIBUS DP master functionality.
Q: What is the maximum program size?
A: Work memory is 32 KB. With an MMC card, load memory can be extended up to 4 MB for data blocks and program storage.
Q: Is this a new or refurbished unit?
A: Konmask supplies both new-in-box and professionally refurbished units. Product condition is clearly stated at checkout. Contact us to confirm availability of new stock.
Q: What warranty is provided?
A: All units carry a 12-month warranty against manufacturing defects. Replacement or full refund is offered for DOA (dead-on-arrival) units confirmed within 7 days of receipt.
