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.
Parameter name RECORD VALID Replies as to whether the action was valid. BUSY Replies as to whether the unit is busy. ERROR Replies as to whether there is an error. STATUS Replies with status information (including error information). LEN Point Description A value is input when reading. Inputs a value when writing. Replies the length of the reply data. To input the ID number for the DL-PN1 into ID, refer to the instruction manual for each PLC.
