HELLO GUYSS.....

I TRY SET CONNECTION WITH MY 2 PLC CONNECTED CPU

I'M USING TWO OF S7 1200 CPU 1214 DC/DC/DC

I TRY TO CONNECT VIA ETHERNET

BUT MY S7 CONNECTION DID NOT CONNECTED AND SEND ME THE MESSAGES IN THE DIAGNOSTIC

ONLINE STATUS : DISCONNECTED

"FAULTY: CONFIGURED STATIC ISO -ON-TCP CONNECTION. CONNECTION IS DISCONNECTED (EITHER BECAUSE NO CONNECTION ATTEMPT WAS EVER MEET OR AFTER DISCONNECTING)"

HERIE IS THE PIC..

HERE IS MY PUT INSTRUCTION AND DIALOG SETTING

Hello UHARZA,

Please explain how you establish the connection?

Do you get any Status on blocks you use?

Best regards,

Wizard

i've checked the Status and Error Parameter

when the req is true, the error sends bit low (zero)

when the req is false, the error sends bit high (one), and the status is 0001 in HEX, then change to 0019 hex it means 25 in decimal, i've read the description about the error = 1 and status = 25

im sure my connection is uninterrupted and in run mode

and also ive checked the memory area at the partner cpu it gives 0000 value in hex

and this pic is about memory area on the partner cpu output

Hello.

From the first picture I see there are conflicts / issues.

My suggestion:

• go offline with your project
  
  
• delete any connection mentioned in
  "devices and networks" > "connections"
  that has anything to do with the PUT action
  
  
• go to the PUT instruction and again choose the partner to link to
  
  
• make sure the security settings of the PLCs allow PUT and GET functions
  
  
• The data blocks used in data exchange should NOT be optimized.
  
  
• Do a complete hardware and software compile of both PLC projects
  
  
• Download & test
  

im using one second timer pulse input to the req,

if i wrong, what should i use to fill the req input ?
