hello,

i have CPU 1212C and i want to communicate with an power recloser that supports the following protocols (DNP3.0, DNP3.0 over TCP/IP, IEC60870-5-101/104). do i need a special communication card to support any of these protocols by the CPU, or the PLC already supports one of them?

Thanks in advance

Thank you.

so the proposed communication module will support both DNP 3.0 and IEC.

I have a good experience with programming modbus RTU using MB_MASTER and so on.

So, my question what blocks needed for either DNP 3.0 and IEC and which one is better?

Thanks

Hi again,

the proposed DNP: 6GK7243-1JX30-0XE0 CP 1243-1 DNP3 module is designed to communicate only to SCADA systems? Or also i can connect it to a third party power recloser that supports DNP

from the recloser data sheet:

Multi-port, multi-protocol communication support (DNP3.0, DNP3.0 over TCP/IP, IEC60870-5-101/104), modem control & dial-up function for SCADA.

l DNP3.0 subset level 3 with information index mapping & class assignment.

my topology:

Recloser (communication protocol: DNP3.0) --> S7-1212c PLC. and this PLC is GPRS direct connect to another PLC to HMI.

Thanks
