Hi all,

I have a Siemens PLC Test rack IM 151-8 PN/DP CPU (ET200s) with a DP-master interface connected to a CPU 315-2 PN/DP via profibus connection. IM 151-8 is my Master and CPU 315-2 PN/DP is my slave/remote plc.

My question is, How can I get the address of the input tag of my CPU 315-2 PN/DP (Slave/remote plc) to IM 151-8 PN/DP (Master)? My program should be loaded only in my master cpu.

I'm using TIA Portal V14 with this set-up and I'm new with it. Thanks for the help.

Hello,

is the 315 PLC already loaded and configured in the Slave mode?
If no then you must load both devices , master and slave.

are both PLC in the same project?
If not you must insert the GSD for the Slave to the project of the Master and configure the defined I/O Slots from the slave as mirror in the Masterproject.

Which input tag you mean exactly?

Regards

Christoph

 Hi ChristophD, thanks for answering.

Yes it is already loaded and configured. And yes it is on the same project file. I just want to see the Digital Input tag of the remote plc in my master plc.

For example, there is a push button connected in my slave plc (315 pn/dp) that when it's activated I can see it activated also in my master plc (im 151-8).

Hi ChristophD,

What program can I use for that?

Thanks and regards,

your TIA Portal?

 I'm using TIA Portal V14. And I don't know what program should I use to copy local I/O.
