General information 2. General information The KRP absolute multiturn rotary encoders are designed for direct connection to the Industrial Ethernet System Ethernet/IP. The Ethernet/IP interface is integrated according to the following specifications: Volume 1: Common Industrial Protocol (CIP™) and Volume 2: Ethernet/IP Adaptation of CIP The specifications can be obtained from the DeviceNet/Ethernet IP user organisation ODVA ( Depending on configuration, the KRP delivers a 24- or 25-bit position value and also a 16-bit wide velocity signal in the unit of steps/gate time via I/O...

SUPREME SENSORING 3.1 General information • On installation, note the data on the physical layer according to Volume 2: Ethernet/IP Adaptation of CIP • Hubs are not permissible. • The cable length between two subscribers may be max. 100 m. • The TWK rotary encoder KRP is equipped with an integrated switch. This not only enables tree and star topologies but also the linear topology. • The setting of addresses, the baud rate or terminating resistors on the device is not necessary. 3.2 Electrical connection The " ...MP01" type rotary encoders have separate connectors for the supply and the...

SUPREME SENSORING Installation • The encoder is then informed of its IP address in the next BOOTP query. • Then save your settings. • If you now mark the encoder in the lower window and click onto Disable BOOTP/DHCP, no further new BOOTP queries are transmitted after the voltage is next switched off/on and the encoder retains its last IP address. Otherwise, a BOOTP server must always be active in the network to supply the encoder with the IP address each time the supply voltage is switched on. • A BOOTP that has been switched off can be switched on again using the Relation List. 3.4 Status...

Project planning with the Logix Designer 4. Project planning with the Logix Designer This chapter explains the procedure for integrating the TWK KRP rotary encoder into the Ethernet/IP network of a Compact/Control Logix control system. The documentation is based on Logix Designer Version 21.03. 4.1 Prerequisites You have created a project (here, KRP_Test) in accordance with your control system structure, including Ethernet network. (Shown here using the example of a CompactLogix 1769) 4.2 Installation of the EDS file • Under Tools, select EDS Hardware Installation Tool. • In the dialogue...

Project planning with the Logix Designer 4.3 Installing the rotary encoder Right-clicking onto the Ethernet system and selecting New Module takes you to the device catalogue (Fig. 8) In the right window, select TWK-Elektronik GmbH. The KRP rotary encoder installed using the EDS file is then shown in the bottom section. Mark this and click onto Create. This then opens the KRP properties dialogue (Fig. 9).

SUPREME SENSORING Project planning with the Logix Designer 4.6 Setting the preset (reference value) It is possible to set a reference value to align a machine position value with the absolute position of the rotary encoder. On setting the reference value, an offset is generated and stored in the encoder, where it is protected against zero voltage. The reference value is set by writing the Preset Value parameter in the Position Sensor Object. This can be carried out e.g. via RSNetworx (see Fig. 13) or from the application programme (as of Fig. 14). ■ Class Instance Editor - [Node...
