1. General The LMC J 0050 3 is an opto electronic distance measuring module for industrial applications. Equipped with a Profibus® DP interface, the LMC J 0050 3 can easily be integrated into any fieldbus driven process controller. The additional SSI interface provides another convenient option for controlled operation of the measuring module.
2.3 Electric Supply Use only 10 V to 30 V direct voltage for LMCJ00503 operation. Use only the specially designated connector terminal for voltage supply. Specified signal levels must not be exceeded, in order to guarantee correct data communication. 2.
3. INTENDED & CONFORMING USE 3.1 General Product Description The LMC J 0050 3 is a laser distance measuring module to determine distances from 0.1 m to 30 m, using natural surfaces, or to measure distances up to 150 m with a target reflector. Providing a red laser sighting point, the LMCJ0050 3 allows you to unequivocally mark a particular target. Its effective operating range depends on the reflectance and surface qualities of the targets being sighted.
3.2 Conforming Use Measurement of distances and output of measured data to the Profibus. Special measuring functions. Compliance with prescribed temperatures for operation and storage. Operation at correct voltage level. Application of specified signal levels to the appropriate data lines. 3.3 Nonconforming Use Do not operate the LMC J 0050 3 in any other way than described under “Intended & Conforming Use“ above and only in a proper working condition.

4.5.4 Slave Address A Profibus address can be assigned, with due consideration of other participants in bus communications, to any number from 0 to 125. The setting of an address can be achieved by triggering an SSA command via the Profibus. For details on how to change a previously set slave address via the configuring tool, you should consult the special tool documentation. In as delivered state, the slave is set to the address “4”. A currently set slave address is permanently stored in the EEPROM.

4.5.9 Description of the ProfiBus Interface 4.5.9.1. General Information The Profibus Interface for LMC J 0050 3 operation control is identical with the Standard DP V0 Profibus (with peripherals decentralized) where V0 designates the version. Telegrams are byte oriented. A byte is also referred to as an Octet in Standard Profibus terminology.
4.5.9.4. Configuration Data For input and output data, the following configurations are available: mandantory class 1 class 2 D1 hex F1 hex 2 words inputs consistency 2 words of input data, 2 words of output data for preset value, consistency optional class 1 class 2 D0 hex F0 hex Not implemented in LMCJ0043 Not implemented in LMCJ0043 4.5.9.5.

4.6 SSI Interface Parameter settings for SSI interface operation can be made via the Profibus. Default state set on initial product delivery: DT Mode. The LMC J 0050 3 has a SSI data interface (SSI = synchronous serial interface). At the request of a SSI clock generator, the LMCJ0050 3 triggers a distance measurement cycle, sending the data bit by bit to a controller for processing in the same order as it arrives at the shift register.
For SSI interface operation, the wiring diagram is as follows: white brown PLC green yellow gray orange blue Power Supply red black violet white/brown white/black Fig. 5: Wiring for SSI interface operation 4.7 Alarm Outputs Parameter settings for alarm outputs can be made via Profibus. This function is only available with the Profibus in active state. Each of the two alarm outputs allows a given object or state to be monitored for positive or negative excession of its limit values.
Distance Distance Fig. 6: Digital switching output behaviour for positive and negative hysteresis. LOW corresponds to a voltage level < 2 V. HIGH corresponds to a voltage level of VCC 2 V. Each alarm output is short circuit proof and rated for a maximum current load of 0.5 A. Parameter settings for alarm outputs can be made with the Profibus master, using the Encoder profile with Class 1 functionality.

This function is only enabled with the Profibus in active state.
The following parameters are available for configuration (refer to GSD File): ExtUserPrmData = 20 “Trigger Mode” for trigger mode ExtUserPrmData = 21 “Trigger Level” for trigger level ExtUserPrmData = 25 “Trigger Delay (31 16)” for trigger delay ExtUserPrmData = 26 “Trigger Delay (15 0)” for trigger delay For detection of a clock edge, the following voltage signals are required: 24 V > HIGH > 11 V 0 V < LOW < 6.
4. Start-Up The table below proposes a sample procedure that may be followed for LMC J 0050 3 start up. It does not purport to provide complete information or exhausting details on all possible applications. For this description, it is assumed that the user will match cabling to his/her specific requirements.
5. LMC-J-0050-3 Operation 6.1 Measuring Modes The various measuring modes are distinguished by the algorithms they use for calculation. The LMC J 0050 3 relies on the phase comparison method for normal operation. In order to obtain a precise measured value, the user should perform an appropriate number of single distance shots at different frequencies of a fixed number.
Desired settings for the Measuring Time, the trigger edge (“Trigger Level”) and the delay in triggering (“Trigger Delay”) can be made in the Master’s configuring tool, using the Encoder profile and Class 2 encoder functionality. Trigger mode must be active. 6.2 Parameters Settings can be made for each parameter in the Master configuration tool, using the Encoder profile and Class 2 encoder functionality. For a description, you should refer to the special configuring tool documentation.
6.2.7 Error Reaction Error Reaction defines how the alarm outputs will react if a measurement cycle is found to have been unsuccessful. Different setting options are available in order to cause error messages to trigger different kinds of response as appropriate for a particular environment in which the LMC J 0040 3 operates.
6.2.10 Switching Point Output 1 or 2 Switching Point Output 1 or 2 corresponds to the trigger threshold of alarm output 1 or 2 respectively. The trigger threshold behaviour is user-definable. For settings of this kind, a switching hysteresis parameter is provided (refer to section 6.2.11). 6.2.11 Hysteresis Output 1 or 2 Hysteresis Output 1 or 2 corresponds to the switching hysteresis of alarm output 1 and 2 respectively.
6.2.13 Average Average allows a floating mean value to be calculated from one to twenty measured single values. Calculation is based on this formula: Mean value x = x1 + x2 + x3 + ... + xn (20) n 6.2.
6. Preventive Care & Maintenance Please note: To remove dust from optical glass surfaces (of transmitter or receiver optics), you may use a pneumatic brush. Do not use solvent containing cleaners to wipe optical surfaces down. You are advised to contact the Manufacturer if there is contamination of a more obstinate nature. Refrain from the use of solvents for cleaning work. You are prohibited from opening the LMC J 0050 3. Do not release any screws of the LMC J 0050 3.
