SINGLETURN ABSOLUTE ENCODER SINGLETURN ABSOLUTE ENCODERS PRESENTATION The Eltra singleturn Proﬁbus encoder series (Identiﬁcation Number 0x0599) is complying to the Proﬁbus DP standard as described on the European Standard EN 50170 Volume 2. Particularly, Eltra Proﬁbus encoders are according to “PROFIBUS-Proﬁle for Encoders, Order No. 3.062”. The Proﬁbus DP interface maintains the same maximum resolution and characteristics (8192 ppr) of the stand-alone version and adds the plus of the Proﬁbus DP network. By the Proﬁbus DP network is possible: · During the periodic data exchange, getting the indication of the angular position from the encoder. · During the set up, setting the resolution as number positions within the single turn. · During the set up, changing the default increase direction count. · To perform the PRESET operation (set the encoder to read a speciﬁc position). · Reading the diagnostic operating mode. · Getting info about the code supplied by the device. Directly from the device it is possible: · To display the ON/OFF status. · To display the device activity on the bus. · Setting the device address. · If requested, inserting in the bus the termination resistance. · Inverting the counting direction. HARDWARE INSTALLATION DEVICE Installing the Eltra Proﬁbus encoder in a network requires the execution of the standard steps necessary for conﬁguring any Proﬁbus DP slave. The sequence of steps is as follow: 1. Commisioning the slave on the master (see corresponding paragraph). 2. Wiring the encoder into the Proﬁbus network using or not terminations depending on the physical position the devices has in the bus. 3. Directly set the address (which must be unique in the network and the same as the one chosen in point 1) for the slave. 4. Preparing the master side application/s and setting up the Proﬁbus network. On the back cover of the encoder (see picture) there is a led inspection window. The device operating status can be controlled by the two led through the window. The green one shows the power presence and must be permanently switched on. The red led switches off only during the periodic data exchange between the Proﬁbus master and the encoder. In the section plan along side the 2 dip-switches of termination line and the 8 dip switches of device address are shown. In the particular shown conﬁguration, the 2 termination line contacts are set to OFF so the termination of the bus in not expected to occur on the encoder. Only seven out of the eight available dip-switches are used to address the slave because the maximum number of devices that can be connected to a Proﬁbus network is 126. For addressing the device, only the ﬁrst seven dip switches out of the eight available are used. The contact number 8 is the LSB while the number 2 is the MSB. The eight

CONNECTION TO THE NETWORK For connecting Profibus encoders to the network, cables within the device can be accessed by the three skintop (in any event only two of them can be used). Usually, a skintop is used for the connection to the bus, a second one to continue the network and the last one to eventually supply the power to the encoder (if the power supply is not available by the network in addition to the RS-485 twin wire). TERMINAL BLOCK ACCESS To access the terminal block, unscrew the two screws on the rear plug and release the rear case from the main one by sliding it out from...
