The operating instructions contain the information necessary for installation, operation and maintenance. Those tasks not requiring special knowledge or skills were not included in the instructions. Repair instructions above and beyond the regular maintenance tasks to be performed are not provided in the instructions. Important notes • • • • • Receiving Inspection Immediately upon receipt, perform a visual inspection of the control unit as defined by the delivery contract. Storage If the control unit will not immediately be installed in its final destination, store it in a protected location to prevent damage from the elements and foreign material. Installation All installation specifications delivered along with the control unit must be followed during installation. Model types Should the documentation provided with the control unit describe other versions of the unit, only that information which pertains to the version of the control unit that was delivered to the recipient shall apply. All features and specifications are subject to technical modification without notice prior to shipment. Duty of instruction The unit may only be operated and maintained by trained and qualified personnel. Prior to initial operation, all personnel that will be operating the unit must familiarise themselves with the documentation provided. Note: These operating instructions apply as of program version DC_SCALE V17A (MEAG) DC_ROLLER V15A (MDDR/T) MEAG-MDDR-MDDT-66499-4-en-1008 © Copyright 2010 Bühler AG Profibus-DP Protocol Table of

The control unit may only be operated by instructed and trained personnel. Repair or replace defective installations or devices immediately. Immediately replace any illegible warning and instruction plates. • Check the operating voltage and frequency with respect to the information provided on the identification plate and in the control cabinet. Note: Warning and instruction plates must be kept clean and must not be removed or covered. It is not intended for any other use.1 Intended use Profibus DP is part of the basic print for MEAG and MDDR/T electronics. 1.Profibus-DP Protocol 1 Safety Note: The operating instructions must be kept near the control unit. • Connect the control unit power supply according to the connection diagram. operation or maintenance of the control unit must have read and understood these operating instructions. For this reason. 1. 1. • Observe regulations issued by local safety authorities. 1. please observe all accident prevention and safety regulations that are contained in these operating instructions and that apply locally. 1.3 Accident prevention The control unit complies with the international safety standard. • Secure the supply lines according to local regulations. • When connecting up or repairing the control unit. Personnel must be familiar with all display and control elements. • • © Copyright 2010 Bühler AG Check the electrical installation on a regular basis. Operating personnel responsible for the installation.2 Duty of instruction The operator is responsible for the training and safety of the operating personnel. For your own safety. MEAG-MDDR-MDDT-66499-4-en-1008 . make sure that the power supply is interrupted by disconnecting all poles and that it cannot be restarted. it is very important that these operating instructions are distributed to these persons.5 Electrical installation Have authorised personnel perform the installation procedures. The SIEMENS SPC3 Profibus controller is used as the communication module according to standard EN 50170. the file BDC_AEE0.1 Technical data Profibus controller SIEMENS SPC3 Protocol Profibus DP built to EN 50170 The protocol consists of 24 bytes of transmitted and received data respectively. the GSD file BUZ_AEE0.

The relevant diagnostic data are set in the Profibus protocol and can be evaluated.DIB is used for the device symbol. the device can therefore be swapped without the need for configuration. Certain devices stop in the event of a timeout for safety reasons. In these devices. Deadlock If the device switches to an invalid state / deadlock. in the event of a master failure or connection problems. Profibus DP is integrated on the basic print and is therefore available at all times. The monitoring time is set at parameter PBDP. The device automatically adapts to the configured baud rate. the corresponding diagnostic flags are set in the protocol. MEAG-MDDR-MDDT-66499-4-en-1008 © Copyright 2010 Bühler AG . 2.
