Page 51: Commissioning And Configuration
In order to be able to establish an UDP communication with the PC, the IP address of your PC and the IP address of the LPS must lie in the same address range. The LPS has no built- in DHCP client, so that you need to set the address manually. This is done the easiest way via the PC. -

Close the configuration dialog by confirming all windows using OK Connect the interface X2 of the LPS directly to the LAN port of your PC. Use a KB ET-…-SA-RJ45 cable for the connection, see Table 14.10 The PC first tries to establish a network connection via the automatic configuration. This takes a few seconds, after which the alternate configuration, which you just set, is activated. -

Page 74: Protocol Structure
Integrating the LPS in the process control (Ethernet) Protocol structure The protocol consists of the Header (30 bytes) followed by the User data. The protocol is used both in command mode when transmitting commands and when acknowledging sensor commands as well as in measure mode. -
Page 75: 10.2.2 Packet Number
Integrating the LPS in the process control (Ethernet) 10.2.2 Packet number The packet number serves internal maintenance purposes of the manufacturer. 10.2.3 Transaction number In measure mode, 0x0000 is always displayed here. In command mode, the command acknowledgment of the sensor contains the command number of the command that is answered. -
Page 76: 10.2.5 Encoder High / Low
X-data (command number 0x5858), each with 376 values of 2 bytes, are transmitted. With the LPS 36HI/EN, values 241 … 376 are set to 0 (compatibility). The resolution is 1/10mm. The Z- and X-data packets have the same scan number; this should be checked in the control. - Page 77 -7000 … +7000 range. Invalid measurement values have a Z- and X-value of 0. If an LPS 36HI/EN is used in a system instead of an LPS 36 without the establishment of connection being changed (Standard-Connect), it behaves compatibly to the stan- dard LPS 36.
-
Page 78: Ethernet Commands
The response of the LPS also corresponds to the "little-endian" standard. For further information, see the note in Chapter 10.2. Note! If the LPS is operated in command mode, the LPS transmits no data (useful for operation with PLC controls). In measure mode, commands Connect to Sensor, Disconnect from Sensor, Enter Command mode, Ethernet Trigger and Ethernet Activation can be processed (is acknowledged with 'Ack'=0x4141). -
Page 79: 10.3.1 Elementary Commands
Command syntax (header/user data), see Chapter 10.2 Using the Connect to sensor and Disconnect from sensor commands, a connection between control and sensor is established or terminated.
