QUESTION:
What must I watch out for when using FTP client blocks (FC 40-44)
for the CP343-1 IT module?
ANSWER:
The FC40 - FC44 (FTP_CONNECT, FTP_STORE, FTP_RETRIEVE, FTP_DELETE,
FTP_QUIT) blocks call the FC5 block internally. So this block must
be available along with blocks FC40-44. It is assumed that the FC5
block called is the AG_SEND block from the SIMATIC_NET_CP library
for CP 300s in version V4.1 (or higher). Version V4.1 of the
AG_SEND block is available with STEP 7 V5.1 SP 2 or higher, while
the FTP client blocks FC 40-44 are available with STEP 7 V5.1 SP 3
or higher.
- If you have a different FC5 in your block folder, you cannot
use the FTP client blocks.
- This solution has been chosen to reduce the size of blocks
FC40-44 and so allow FTP blocks to be used with smaller CPU31x
too.
