Overview of PROFINET What is PROFINET? PROFINET is an open industrial networking standard developed and maintained by the PI (PROFINET International). All supported devices can use the communication network regardless of the vendor. PROFINET allows easy integration with the currently used field bus (such as PROFIBUS), enabling you to protect the existing assets without modifying the legacy system.
Specifying the IP address using the DCP protocol In the PROFINET communication, you can specify the IP address of I/O devices using the DCP protocol (Discovery and Configuration Protocol). The DCP protocol offers two methods for setting the IP address. (1) The IP address can be set by the I/O controller based on the device name information of the I/O device. (2) The IP address and device name of the I/O device can be set by the I/O supervisor (PC, etc.).

Record Data Communication What is record data communication? Record data communication is a function that performs communication by issuing commands when desired. It is used for applications which do not require the punctuality of data I/O communication, such as reading and writing I/O device settings.

In % mode: +999.99: The value is above the upper limit of the display range. -999.
*10 The result of the "initial reset request" motion command is included in this item. Regarding Data No. 53 (EEPROM writing result), a "0: writing in progress" status is maintained for 2 seconds after completion of the final write command transmission to the nonvolatile memory (EEPROM). Writing begins 2 seconds later, and if completed normally, the result is "1: successfully completed". Example: After every-second write command transmissions, a "0: writing in progress" status is established for 2 seconds.
*13 This command reads the execution result of the "tolerance tuning request", "2-point tuning HIGH side 2nd request", or "2-point tuning LOW side 2nd request" motion command whichever was last issued. *14 This parameter works if "Bank switching method" is set to "button." *15 These parameters are OFF only if data "0" is written and the wiring is configured to turn off external input.
