GEK-113000-AFF650 DIGITAL BAY CONTROLLER 7-1 F650 Digital Bay Controller Chapter 7: Frequently asked questions GE Grid Solutions FREQUENTLY ASKED QUESTIONS 7.1 Communications Q1. Does the F650 support DNP and ModBus over the Ethernet port? A1. F650 units support both protocol s over both the asynchronous serial ports and the Ethernet LAN synchronous port using TCP/IP and UDP/IP la yers over the Ethernet. Q2. Does this equipment support dual IP access? A2. Yes, it supports two independent IP addresses in aliasi n g mode. Those address go in the communications settings Network0 and Network1. Q3. Is the protocol IEC 870-103 supported by the F650? A3. Yes, IEC 870-103 is supported by the F650 in f irmware version 5.00 and higher. Q4. Can the F650 be used as a DNP master station? A4. Not at this moment . It works as a slave IED station for all protocols. Q5. How many communication ports are included in the F650? A5. The equipment has 2 different boards, one for asynchronous serial ports and another for a high-speed synchronous E thernet port . The f irst board has 2 comm ports, COM1 and CO M2. COM2 is multiplexed with the front serial RS232 port , whereas the COM1 port is comp letely independent from COM2. The synchronous LAN port is ETH_1/ETH2 or ETH_E/ETH_A/ETH_B (Depending on model. Q6. Are there one or two Ethernet ports? A6. The equipment has only 1 Ethernet port . For redundant f iber op ti c versions, redundancy is done at the physical level (f iber optic) but there is just one port .
7-2F650 DIGITAL BAY CONTROLLER GEK-113000-AF 7.1 COMMUNICATIONS CHAPTER 7: FREQUENTLY ASKED QUESTIONS Q7. How many different communication Ethernet sessions can be opened through the LAN port? A7. ModBus TCP/IP:4 sockets DNP TCP/IP:3 sessions (from version 1.72 on) Q8. May I use the cooper 10/100 BaseTX connection included in the basic model with all protocols? A8. Yes, it may be used with all protocols. In noisy substation en vironments and/or long distances, it is recommended to use f iber optic options due to much better EMC performance and immu nity. For f iber optic models, it is necessary to adjust an internal jumper to use the copper port . Q9. Remote I/O CAN bus. Does it suppor t DeviceNet protocol? A9. No it does not support DeviceNet . Q10. Which functions are available in the relay web server? A10. Currently, it includes several functions fo r viewing measures and retrieving information. Q11. Q11 May I use URPC to program the relay? A11. Only oscillography records may be viewed with URPC once downloaded to a f ile using the ENERVISTA 650 Setup software. Q12. May I connect URs and F650s to the same Ethernet? A12. Yes, either in cable as in f iber, or even mix them. Q13. How do I connect with f iber 10-BASE-FL UR relays with 100-BASE-FX F650 relays? A13. Take into account that an UR is never connected directly to a F650 (neither two UR nor two F650 with each other) but they ar e always connected through a hub or switch. The hub or switch where the URs are connected must be 10-BASE-FL and the hub or switch for the F650 must be 100-BASE-FX. Q14. How do I connect with cable 10_BASE-T UR relays with 10/100-BASE-TX F650 relays? A14. The answer to this question is as described before but also in this case there is an advantage added, because the hub 10- BASE-TX port is able to understand a 10-BASE-T port . This means that a hub 10-BASE-T port may be connected to an UR or a F650, and a hub 10/100-BASE-TX port may be connected either to an UR or F650. Q15. What happens with f iber optic connectors compatibility, b ecause the hub that I have has a different connector to the one of the F650, although both are 100-BASE-FX? A15. Just buy f iber cables with the appropriate male connectors . For the UR and F650 side we need the same connectors, ST type, for the hub side, the correspondent ones. And in what concer ns to the f iber type, it is used the same for 10 as for 100, it is the 50/125 or 62.5/125 multimode, this last one allows longer distances. Q16. What is the difference between a hub and a switch? A16. In a repeater type hub (shared hub), one unit talks and the rest listen. If all the units are talking at the same time ther e may be collisions in the messages, what may produce certain communication delays. The switch (switched hub) has very powerful processors and a lot of memory and it is much more expensive than the hub. It directs messages to the proper destination avoiding collisions and allowing a much more efficient communication. Q17. Why do we have 10/100 compatibility for cable but not for f iber?
CHAPTER 7: FREQUENTLY ASKED QUESTIONS7.2 PROTECTION GEK-113000-AFF650 DIGITAL BAY CONTROLLER 7-3 A17. The cable has some advantages that the f iber does not have, and it is that the signal attenuation in short and medium distances, is worthless and this is truth for low and high frequency signals. By the contrary, the light in one f iber optic is highly attenuated, being much worse in case of high frequenc ies than in the low ones. The 10-BASE-FL f iber transmission is performed in a wavelength of 850nm, what allows a less expensive electronic than the 1300 nm used in 100-BASE-FX f iber transmission. Using, in both cases, the same glass multimode f iber type, the attenuation to 1300 nm is lower than the 850 nm ones, this way the greater attenuation of the 100 Mbit s is compensated. There is another f iber standard, the 100- BASE-SX, which uses 850 nm to 100 Mbits, being compatible with the 10-BASE-FL one, although it sacrif ices the maximum distance to 300 m. Nowadays, this standard has not had success among Ethernet equipment manufacturers and suppliers. 7.2 Protection Q1. Does the F650 support IRIG-B signals? Which type and accuracy? How many units may be connected to the same source? A1. Yes, the F650 includes an IRIG-B input for all models, including the basic ones. It uses DC level format B. Form ats used are B0000, B0002 and B0003. Actual accuracy is 1 millisecond. Internal sampling rate allows true 1 ms accuracy time tagging. The input burden is very low. The maximum number of units that may be connected to a generator depends on its output driving capability. Up to 60 units have been successfully connected with equipments commonly used in the market. Q2. Does the equipment work with dry inputs in both AC and DC? A2. The equipment works only with DC inputs. Inputs should be driven with externally generated DC curren t. No special 48 Vdc or other outputs are included in the equipment to drive these inputs; therefore, contacts connect ed to the equipment should be connected to a DC source. Q3. Is it oscillography programmable? A3. Yes, the sampling rate is programmable (4, 8, 16, 32 or 64 samples per input). The depth depends on the sampling rate. Q4. Do I have to select a different model for 1 or 5 A? A4. No. The same model is able to work with either /1 A or /5 A rated secondary currents. There are high accuracy sensing transformers that allow the use of any current input through th e same terminals to reduce the spares and simplify wiring. Q5. In my installation, several digital inputs become active whe n I energize the transformer. How can I reduce sensitivity? A5. By selecting debounce time and/or voltage threshold, the relay may adapt its sensitivity to different applications. Select th e maximum voltage threshold and debounce time (recommended 15 ms) to minimize AC coupling effects.
7-4F650 DIGITAL BAY CONTROLLER GEK-113000-AF 7.3 CONTROL & HMI CHAPTER 7: FREQUENTLY ASKED QUESTIONS 7.3 Control & HMI Q1. What is the difference between Get/Send info from/to relay and Upload/Download info files to/from relay? A1. Get/Send are used for settings and configuration storage that al though both are in a unique file, are sent separately in two times. Upload/Download are used for projec t or PLC files group storage. These files are the setting_configuration file source. To operate, the F650 does not need the source files; the Upload/Download tool is destined to serve as historic file. Q2. can I program interlocks? A2. Yes, via ENERVISTA 650 Setup interlocks may be programmed from very simple to advanced schemes. Q3. Can we rotate the display 90 degrees to show feeders vertically? A3. No. The product has been designed to view it in ho rizo ntal mode (landscape) due to the following reasons: It is easier to read the LCD display because it has been designed for horizontal positions. Compatibility between text display (4x20 characters) and LCD displa y (16x40 characters or 128x240 pixels). Refresh speed is better in horizontal than vertical format. Q4. Do I need a laptop or handheld to program the unit? A4. No, all main operations can easily be performed with just t he incorporated HMI. Handheld or laptops may be required to download large quantities of information (such as oscillograms, etc.) but they are not mandatory for a conventional user that just needs to change settin gs, view measurements, states, etc. Q5. Is there password security for protection and control? A5. Yes, there are two passwords. An independent password for protection changes and control operations is available since ver sion 1.44 Q6. Is it possible to have a remote HMI installed in the fron t of the panel with the rest of the relay in the rear side? A6. Not in the present version. Q7. Is it possible to program a default screen for the HMI? A7. In graphic display versions the user may program a custom scr een with the single-line diagram, measurements, etc. In text display models, there is a choice of logo, measurements, or scrolling both screens. Q8. May I force inputs and outputs to ease commissioning and testing? A8. Yes. Q9. How can I disable the rotary knob buzzer? A9. Press ESC key more than 3 seconds and then press the knob during a short pulse. Q10. Why do appear strange texts on the display when switching on the relay? A10. You have pressed any button and the HMI has entered test mode. The display messages are updated after a few minutes, on ce the relay has completed the starting sequence.
