PUT Instruction

I'm using two CPUs 1214C and I'm trying comunicate these PLCs but unsuccessfully. My question is: if these PLCs are able to write data (PUT) or just read data (GET) from an other CPU that's is able to write.

Thanks,

Hello,

sry but for first it is needed post exact order number of your CPUs, because with versions and firmware are some implementation of protection/access. So look to your CPU properties and check some option like: allow communication with PUT/GET. This must be enabled by you and downloaded to both CPU, of course due versions of your CPUs.

hi MCeCiM,

Put and Get should be possible.

Maybe an application sample is helpful for you

How do you program the "GET" and "PUT" instructions in the user program of the SIMATIC S7-1200 CPU in order to transfer more than 160 bytes of data?

What are the differences between the PUT and GET instructions for S7 communication and S7 basic communication?

hope this helps,

regards,

Hello,

Sounds good👍,

Now while getting error bit move the status of GET or PUT block in some other memory location of PLC and post it here.

GET/PUT instructions are used in single side , not in both PLC.

Either you can use DB for Reading / Writing  or you can use memory address directly.

Eg P#DB1.DBX0.0 WORD 10 at local address and P#DB1.DBX0.0 WORD 10 at remote address.

Or P#M100.0 Word 10 at local and remote address.

If it is DB then you need to create DB  with same number at remote PLC which is defined as Remote data adddress In either GET or PUT block.

Hi, another option is to use the TSEND_C and TRCV_C. Here´s the manual of how to use it.

Hope this helps.

Hello,

See the attached video for GET/PUT communication.
