39 1. Installation 1.5 Optical-fibre waveguide connection for PROFIBUS-DP Optical-fibre waveguide technology is to be recommended when transmission is affected by heavy interference, as well as for extending the transmission range when high baud rates are used. This also offers the following advantages: high EMC compatibility, ESD protection due to the optical transmission of signals protection against lightning potential isolation of the individual DP slaves. The PROFIBUS-DP interface of the CPX terminal has been designed in accordance with specification EN Volume 2, and can therefore be used for controlling network components for optical-fibre waveguides. Example of optical-fibre waveguide network components: Siemens Optical Link Module (OLM) for PROFIBUS plus Siemens Optical Link Plug (OLM) for PROFIBUS (IP20) HartingHan-InduNet Media converter IP65 in combination with adapter cable for Festo valve terminals (optical data transmission in DESINA installation concept). 1-25

40 1. Installation 1.6 Pin assignment of power supply Warning Use only power units which guarantee reliable isolation of the operating voltages as per IEC 742/EN 60742/VDE 0551 with at least 4 kv isolation resistance (Protected Extra Low Voltage PELV). Switch power packs are permitted, providing they guarantee reliable isolation in accordance with EN 60950/VDE By the use of PELV power units, protection against electric shock (protection against direct and indirect contact) is guaranteed in accordance with EN /IEC 204. Safety transformers with the adjacent symbol must be used for supplying PELV networks. The CPX terminal must be earthed to ensure that it functions correctly (e.g. EMC). The current consumption of a CPX terminal depends on the number and type of integrated modules and components. Read the information on power supply as well as on the earthing measures to be carried out in the CPX system manual. 1-26

98 3. Diagnosis Siemens SIMATIC S5/S7 With these controllers, you have the possibility of determining the reaction of the CPX terminal to the faults named (details see controller manual). Almost all configuration programs contain the function Response monitoring. For the operating modes named, the time specified corresponds to the drop-off time of the valves and electric outputs. Further details on response monitoring can be found in the relevant manuals. 3-24

99 3. Diagnosis You can set two ways in which the control system reacts to faults: when a fault occurs, the controller switches to the operating mode STOP (hard fault reaction) or when a fault occurs, the controller remains in the operating mode RUN (soft fault reaction).

108 A. Technical appendix A.2 Operation with the general DP master The Festo CPX terminal can be controlled from any PLC, PC or industrial PC with a PROFIBUS-DP module in accordance with EN (DIN 19245). Information on the functions FREEZE, SYNC and the DP identifiers can be found in section A.2.1 Bus start In order to commission the CPX terminal correctly, the DP master must carry out the following functions in the sequence specified: 1. Request diagnosis. 2. Send parametrizing data. In the case of the start parametrizing, the parameter set will be loaded into the field bus node by the master. The node distributes the parameters to the modules. 3. Send configuration data. 4. Diagnosis request before data exchange. 5. Start cyclic exchange of data. The composition and contents of the individual telegrams are described in the following sections. Please note After each interruption of the field bus system (e.g. after interruption of the power supply to the field bus node), the parameter set will be sent again by the PROFIBUS master to the field bus node. An exchange of individual CPX modules is therefore possible without the need for manual parametrizing. A-4

114 A. Technical appendix A.2.4 Error treatment With the function Set_Prm you have the possibility of determining the watchdog time (WD_Fact_1, Octet 2, WD_Fact_2, Octet 3). The reaction of the CPX terminal to a fault (e.g. bus failure) depends on the parametrizing. Further information can be found in chapter 3.6. A.2.5 Request diagnostic information Slave_Diag The diagnostic data are requested by the CPX terminal with the function Slave_Diag. A description of this function can be found in section 3.5.3, Diagnosis via PROFIBUS-DP. A.2.6 Start cyclic exchange of data Data_Exchange The cyclic exchange of data is accomplished with the function Data_Exchange. With this function the output data for CPX terminals are transmitted as an octet string of length x. The octet string length depends on the number of identifier bytes. Please note With the function Data_Exchange, the CPX terminal expects the output information for the valves and electric outputs. The input information is sent to the master as a reply telegram.
