We’re currently working on a SIMATIC S5 system and looking for the function block (FB) library for the Ethernet communication card CP535 (part number 6ES5535-3LB12 – CP 535 for SINEC H1, without the 15V voltage module, available as exchange only).
Specifically, we need the following blocks used for HTB (High-speed Transfer Block) communication:
If anyone has this library or knows where it might be found (any documentation, download, or archive), I’d really appreciate your help.
Thanks in advance!
