what are the various possible way of communication with OP27. how to check transfer setting as unable to enter transfer settings??


1. Power OFF.
2. Keep pressed ESC+Aroow UP
3. Power ON.
4. System switches to Download Mode. (you will see a message).
5. Release the buttons.








I am using   Siemens PLC (S7-200 CPU  .Micro Win V4.0  SP 8, and for communication  am using ppi adapter.the plc can not communicate with the computer .it gives me
  "The port cannot be opened, or  is being used by by another application.


Shutdown all applicatons, look in your startup folder for applications that might use the same (pc) port.
Restart PC.
Start microwin and select right pc/pg interface.
Put CPU in stop mode and try again.

  TIA Project Migration Project will be automatically migrated to TIA V17, if it is prepared in TIA V13 SP1 or higher. The option packages needed for the project must be installed on your system in current version. TIA project with version less then TIA V13 SP1 is to be firstly compiled in TIA V13 SP1 and then can be opened in higher version. Compile can be done as below: Compile -------> Hardware rebuild all Compile-------> Software rebuild all In case of opening lower version project in TIA V17, you may get below error "upgrade project (0025:000219) TIA V14 and higher no longer support S7-1200 CPU with firmware V1.0 In case if we have to work then we have to configure CPU with firmware 4.0 offline or while opening project of S7-1200 CPU with firmware V1.0 below error will occur.

S7-1500 Memory Concepts

-
Image
  Below is the memory area overview:  Load Memory Non volatile memory for User program, data blocks, technical object, recipe and data logs. We can copy additional data to load memory through a web server or explorer. An inserted Memory card is required for operating the CPU. For CPU 1518, extra load memory is required for : Linux runtime which runs in parallel with CPU runtime C/C++ runtime application CPU function libraries. Linux runtime is the environment required for execution of a runtime application and CPU runtime is required for applications requiring CPU runtime application. Work Memory Work memory contains executable code and data blocks. It is integrated in the CPU and cannot be extended. For CPU 1528-4PN/DP additional work memory is required for CPU function libraries and C/C++ runtime applications. Retentive Memory It is a non volatile memory for saving limited amount of data in case of power failure. It can be deleted with memory reset or reset to factory setting. Additi
