HMI CP6xx with one/two ETHERNET Ports

HMI CP6xx with One/Two ETHERNET ports on HMI with standard ETHERNET switch (unmanaged switch):

Recommended high availability connection. Option 4.

If application requires only CPU redundancy and no ETHERNET redundancy, the users can use standard ETHERNET switch (unmanaged switch) with CP6xx HMI.

HA example application program (Example_AC500_HA_CS31_V242.project) provides a sample application program for CP620 HMI. It has the required scripts to read the data from the primary PLC. Also it provides an option for the user to select one of the two PLCs to read data. This is done using the IP override functionality. With minor modifications the HMI application program can be made application specific.

Note

Data writing from HMI to PLC is not recommended as it will write data only to the primary CPU.
