The new functionality of C37.94 for SWT 3000 supports only the standalone device. The feature is implemented in PowerSys versions ≥ P3.4.120, except for P3.5.100. 1.2 Short Description of the New Feature . The SWT 3000 is operating via optical fiber with multiplexer or data converter that supports IEEE C37.94. For each transmission direction, a separate fiber is necessary. Figure 1-1 SWT 3000 Configuration with C37.94 Table 1-1 Specification of the Fiber-Optic-Module FOS-3 Fiber type Multi-mode with modules using 850 nm-wavelength Wavelength 830 nm Optical connector LC connector Range Approx. 2 km at 850 nm (depending on the fiber used) 2 x LED TX and RX-Alarm Clock FOM_C37.94 is DTE (for test purpose, a switchover to DCE is possible) Note For more information, refer to the Equipment Manual, Chapter Technical Data. Note 1. Both SWT 3000 have the same FOM C37.94 module and the same configuration (that means the same data rate). 2. FOM C37.94 can be used as primary or secondary path and in any combination with other digital or analog interfaces on another path. 6 Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 SWT 3000 Stand-Alone Device with C37.94 1.2 Short Description of the New Feature CAUTION Exercise caution with laser beams of the optical plug-in modules. The laser beams can damage your eyes. If you do not comply with the safety notes, this will result in medium severe or slight injuries. ✧ Do not look directly into the optical fiber terminals of the active optical plug-in modules, not even with optical devices. Note Laser class 1 is adhered to in compliance with EN 60825-1 and EN 60825-2, in the case of ≤ 62.5 μm/125 μm optical fibers.

This connection is used only for testing the connection and functionality of the FOM_C37.94. In normal operation, the mode C37.94-DTE is used and the clock source is the external multiplexer or data converter. 8 Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 SWT 3000 Stand-Alone Device with C37.94 1.3 Configuration of the Digital Line with C37.94 Configuration of the Data Rate If C37.94 has been selected in both digital interfaces boxes, the data rate 1 corresponds to the digital interface 1 and the data rate 2 corresponds to the digital interface 2 (refer to the following figure). Figure 1-3 Configuring Both Digital Interfaces Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 9 SWT 3000 Stand-Alone Device with C37.94 1.3 Configuration of the Digital Line with C37.94 If only one interface has been selected, only the corresponding data-rate field is enabled. The other one is disabled (refer to the following figure). According to IEEE C37.94, the data rate must be 1 to 12 x 64 kbps. It can be selected via the list box of data rate 1 or data rate 2 in tab System of the SWT 3000 – Configuration. Figure 1-4 10 Configuring the Data Rate Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 SWT 3000 Stand-Alone Device with C37.94 1.3 Configuration of the Digital Line with C37.94 For the standard configuration C37.94 DTE, it is also possible to detect automatically the data rate of the DCE device by selecting Auto in the data-rate field. Figure 1-5 Configuring the Data Rate by Selecting the Option Auto Note For the setting of the Tx and Rx address, Siemens recommends using a pair of 2 different address numbers as stated in the following table. Table 1-2 Example of TX and RX Addresses Device A Device B TX-add. = 1 RX-add. = 1 RX-add. = 2 TX-add. = 2 Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 11 SWT 3000 Stand-Alone Device with C37.94 1.3 Configuration of the Digital Line with C37.94 1.3.2 FOM Type Information . The FOM type that was plugged into the slot can be read in the field Firmware-overview. The type must be C37.94 (refer to the following figure). Figure 1-6 12 Firmware-overview with C37.94 Type Communication Solutions Teleprotection Signalling, Application Notes C53000-X6076-C237-1, Edition 03.2012 SWT 3000 Stand-Alone Device with C37.94 1.3 Configuration of the Digital Line with C37.94 If a FOM board type other than FOS-3 is plugged into the slot and the FOM board is configured with the C37.94, the hardware alarm and configuration alarm are issued. The type of FOM board appearing in the field must be FOM (refer to the following figure).
