Support of multiple passive connections per port by communication processors of S7-1500 and ET 200SP
Contrary to the information in the function description and in the interoperability list no guarantee can be given for the "Multiport" function (support of multiple passive connections per port) for the following modules.
|CM 1542-1||6GK7 542-1AX00-0XE0|
|CP 1543-1||6GK7 543-1AX00-0XE0|
|CP 1542SP-1||6GK7 542-6UX00-0XE0|
|CP 1543SP-1||6GK7 543-6WX00-0XE0|
The listed modules only support the function if the property "Support of multiple passive connections per port" is specified with "Yes" in the technical data of the modules.
Alternatively the following solutions are available:
- Use of different port numbers (2404 and 2405, for example).
- Use of the active instead of passive established connection.
- Distribution of the passive connections to multiple CM/CP modules.
- Use of the local PLC interface(s), because the PLC support the "Multiport" function.
