Hi all,

I have an 315-2 DP (315-2AF01-0AB0) which I would like to replace to a newer model, what would be the replacement for this PLC as its around 20 years old. 

Thanks for help.

Hello,

Kindly have a look at the following topics:

1-6ES7315-2AF01-0AB0

Successor product:

6ES7315-2AF03-0AB0

2-What should you watch out for when changing from one S7-300 CPU to another?

Changing from one S7-300 CPU to another CPU with an almost identical order number:

If the only difference between the order numbers is the last digit of the middle block, for example a CPU with the order number 6ES7315-2AF01-0AB0 is to be replaced by a CPU with the order number 6ES7315-2AF03-0AB0, then compatibility of spare parts is ensured.

Changing from a standard CPU (S7-300) to another or larger CPU:

For the following group of CPUs (discontinued products)

Designation	Order number
CPU 313, 12 KB	6ES7313-1AD03-0AB0

Hello,

you have original project?

If no = 2AF03 (Big blue MC card)

If yes = 2AG10 (MMC card) I think is possible also with 2AH14

Hi all,

Would any of below be suitable for replacement of 6ES7315-2AF01-0AB0 ?

Hello Boost34,

.....

Would any of below be suitable for replacement of 6ES7315-2AF01-0AB0 ?

• 6ES7315-2EG10-0AB0 - yes
• 6ES7315-2EH13-0AB0 - yes
• 6ES7315-2EG14-0AB0 - you mean EH14? - yes

It should work with all this 3 types.
The difference are better performance and more working memory.
