Hi 

For the redundancy CPU's. The Modbus TCP client, do we need to use “ MB_RED_CLIENT” block. Please advise with the sample program 

Which port to configure as the modbus tcp client for the H-system in TIA portal.

I'm using the CPU 1515R-2 PN. Part No : 6ES7 515-2RM00-0AB0.

with regards,

Hi,

I just set up the two CPU’s 1515R-2 PN and downloaded the program. It downloading on PLC-1, but not sync with PLC-2.

Also for the testing I assigned IP address for the X2 port – 10.176.3.21 and later I changed to the original IP address 10.176.3.20 in the device configuration for the X2 port and downloaded. It’s not changing on the backup CPU.

After downloading the hardware configuration, I turn the CPU’s to RUN. Only primary CPU goes to RUN mode and backup CPU is still in STOP mode.

When I check on it, the project only downloading to the primary CPU and not loading to the backup CPU.

Please advise. Thanks

Hi there, 

Did anyone solved this problem? 

Shall We consider S7-1500 in redundancy application?
