HA-CS31 Library - Overview Diagram¶
The following table gives an overview which function blocks and functions run on CPU and on CM574 (slot 2 to 4). In this example slot 1 is used for CM577-ETH for program download. Function blocks marked in italic font are only available from HA-CS31 library version V2.4.0. In another case if a user has a PLC with more than one onboard ETH (Example: PM595, PM591-2ETH) the user can use ETH2 port for downloading e.g. the program, webserver, OPC server communication etc.
