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.

The PROFINET communication for the DL-PN1 series supports the PROFINET I/O communication, which transmits data between I/O controllers (PLC etc.) and I/O devices, and complies with Conformance Class A.

The PROFINET I/O communication offers the following two types of communication methods for cyclic data: Real-time communication (RT) and isochronous real-time communication (IRT). Real-time communication provides similar communication performance as the existing field bus, such as the device control in normal factory automation, using Ethernet. The isochronous real-time communication is capable of meeting stringent real-time requirements, including synchronized motion control.

The real-time communications offer the following two types of communications: Data I/O communication for sending and receiving data periodically, and record data communication for sending and receiving commands/responses at arbitrary timings. In the data I/O communication, you can set the Update time (Communication cycle) based on the priority of the data to be sent/received, enabling sending/receiving of data with adjusted overall communication load. The record data communication is used for communication applications that require little punctuality (unlike the data I/O communication).

The DL-PN1 Series supports real-time data I/O communication and record data communication.

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.).

If the IP address of the I/O device will be set by the I/O controller, the I/O device name must match the name in the config of the I/O controller.

The DL-PN1 can connect to multiple sensor amplifiers (a single main unit and multiple expansion units) which support D-bus. "D-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers. Different types of sensor amplifiers with D-bus support can be connected to a single DL-PN1 unit.

How many and what types of sensor amplifiers can be connected depends on the sensor amplifiers or units to be connected. Please inquire for details.

Assigning ID Numbers and Slot Numbers

Several sensor amplifiers can be connected to the DL-PN1. ID numbers and slot numbers for data identification are assigned to each sensor amplifier. The method for assigning ID numbers and slot numbers is as follows:

• The numbers are assigned in order, starting from the sensor amplifier that is the main unit. (Optional numbers cannot be assigned.)

• 00 is assigned as the ID number and slot number of the DL-PN1.

• You cannot change the ID numbers and slot numbers assigned to the sensor amplifiers.

• In this manual, ID number 00 to ID number 04 are denoted as ID00 to ID04, and slot number 00 to slot number 04 are denoted as Slot0 to Slot04 respectively.

Data I/O Communication

 What is data I/O communication?

This function enables cyclic (i.e. in fixed intervals) data communications with the PROFINET devices. This function provides high-speed control with several to several tens of milliseconds. The communication can be controlled by referencing and updating the variables in the PLC, making it easy to control the programs on the PLC side.

page

• Communication settings for the data I/O communication, such as Update time (communication cycle) and the data size, will be configured on the PLC side.

• In a network with many connected devices (including the PROFINET devices), a network delay and/or packet loss may occur when there is a heavy load on the network. Conduct a thorough verification before the operation.

(2)

This example shows how to read the comparator values (P.V.values) from the sensor amplifiers ID01, ID02, and ID03.

(1) When the comparator value of a sensor amplifier is updated, the value of the input

address is also updated via data I/O communication. If the judgment value is correct, the parameter range is

- from - 999.99 to +999.99 (percent mode).

- from - 99.999 to +99.999 (size mode). If the comparator value is over range, under range, or invalid, the previous value is retained without updating the comparator value. To confirm whether the current value is correct, use the comparator value property.

(2) The comparator value invalid, comparator value over range, or comparator value

under range is entered. If the comparator value of a sensor amplifier is "invalid", "over", or "under", the bit corresponding to the ID number of that sensor amplifier flips to 1.
