  1. What type of input: npn or pnp is used? Is it n/p pin connected acording to the manual? It is the 4, 6 status led - it must show the input pulse on/off. Where is connected 5,7 pin?
  2. I recently met with a PLC that had a power supply with supercapacitors UPS to keep it running when the power went out. Like this: https://www.neousys-tech.com/Resource/Product_Document/PB-9250J-SA/pb-9250j-sa-industrial-intelligent-supercapacitor-power-backup-ups-module.pdf?20190523
  3. One of the app note http://apps.geindustrial.com/publibrary/checkout/AN18-001?TNR=Application and Technical|AN18-001|PDF&filename=AN18_001_Connecting power supplies in parallel.pdf Sample https://www.power-supplies-australia.com.au/blog/connecting-mean-well-power-supplies-parallel
  4. Second one is universal Bluetooth access point with standard classic 2.1 and 4.0 mode.
  5. this is maybe industrial https://www.anybus.com/docs/librariesprovider7/default-document-library/brochures-datasheets/anybus-wireless-bridge-serial---datasheet.pdf?sfvrsn=2 or https://www.anybus.com/docs/librariesprovider7/default-document-library/brochures-datasheets/Anybus-Wireless-Bridge-II.pdf
  6. find doc in french http://www.pl-systems.fr/wa_files/bluetoothinstallation_022016.pdf but no com module with BT on Unitronics site :(
  7. I try to compare V200-18-E46B 24VDC I/O module and a Siemens 24VAC input I/O module. It is interesting that the input electrical schematic diagram of both modules are actually the same since the PS2705 optical converter is used. In V200-18-E46B PS2705 it is used for switching PNP or NPN logic. It seems to me that the difference is only in the response time - 10ms for Unitronics 24VDC I/O and 25ms for 24VAC siemens I/O. So I think that to work with a 24VAC one diode (or 4diode bridge) and a small (0.1-0.47mF) capacitor are enough. However, keep in mind that AC experiments should be done
  8. Some sensors work as an antenna. If the frequency converter is turned on, they catch its signal and generate a false signal at the output. In this case, it is advisable to try to activate the sensor with the disconnected VFD.
  9. Is it this VFD settings correct? P00.01 Run command channel = 2, P00.06 or P00.07 Frequency command selection = 8
  10. If it possible please explain MB38. MB1 has different action.
  11. MF1 - mm/imp - how many mm will go raw material when encoder weel run = 1 imp See image MF1 calculation: rung4 240 = 4*60sec 4 = 4x encoder mode
  12. You must do some math ..... FREQ to RPM.... in my project example i need to calc m/min from ML5 FREQ
  13. I try to post some solution from my project Please try to do something like that: ML5 is used for FREQ SPEED calc from ML5 FREQ MESURE
  14. Is it possible to post the name plate of servo and motor?
  15. Please explain is it 100 sensor need to connect to one panel or 25 panel with 4 sensor on V200-18-E3/4XB? Maybe modbus version of current sensor is cheapest variant. Even if you use something like that http://www.loreme.fr/fichtech/HCM d33_eng.pdf Analog version need 100 analog input... and minimum 25pcs V200-18-E3/4XB. Modbus has more than 100 address and do not need V200-18-E3/4XB. But as Joe explain, this task is not simple in both - analog or modbus version.
  16. Something like this with Modbus https://www.aliexpress.com/item/32977623982.html?spm=a2g0o.productlist.0.0.29fd4687btW6qC&algo_pvid=40fea82f-c7a6-4431-b668-0b2e8cd0c535&algo_expid=40fea82f-c7a6-4431-b668-0b2e8cd0c535-33&btsid=60263821-ef36-474f-97f1-b2fdc5c9830c&ws_ab_test=searchweb0_0,searchweb201602_8,searchweb201603_52
  17. It is impossible for SM35 J R20. You need to use SM35 J RA22 or SM35 J TA22.
  18. SI 101 TCP/IP retries base time out Legal values are 1 to 10, units of 100 msec (1 stands for 100 msec etc.) Default value is 200 msec. Same value is for ALL 4 sockets Requires CARD INIT Illegal value request will be rejected (no change)
  19. I would add the following points: 1.1 Set the type of input signals PNP, NPN or ANALOG MODE (if input present or installed); 1.2 Set the mode of operation for ANALOG inputs (if confiured in p.1.1) 1.3 Setup communication RS232/RS485 or(and) CAN card and determine their mode of operation and termination. 1.4 Make foto for all components that is not in original factory configuration and foto of PLC and IO nameplate. 11 Setup NEW password for program or (and) info mode if needed (type this passwords in project with comment). 12. Fix on paper SN of panel and IO module, passwords,
  20. You do not need a special program to test. Please setup the connection to the pre-configured V430 PNP input. Use only 3 wires. A - HSC0, B - HSC1, GND - V0 ... The ecoder must be connected to the V350 and to the original system at the same time. +24V encoder wire connected only to original system. Please place on the screen the ML that is connected to the HSC 4x Shaft encoder input. After that, please place the Reset button on screen and the program one rung for clear ML to "0". Testing -> clear the ML, start the machine, wait for the stop in the programmed position, read the ca
  21. In manual for this controller (P8721) https://www.process-controls.com/Hirotronix/pdf/elgo/P85_P87_P88.pdf i see encoder monitoring function. In this case your test program calculated the same numbers as original controller. Now you try to program length on P8721 and this controller display needed length when metal stopped. But real length is not OK. Is it true? Maybe mecanical problem in metal sheet transportation present. Please check all motor, pulley, belts, coupling.
  22. In my opinion, the HMI controller term slightly reduces the concept of the OPLC. Now on the market, there are controllers (named HMI controller) that exclusively show on the big screen what PLC is doing now, however, they have nothing to do with the concept All in one. I would use the term OPLC to explain students the difference between the classic HMI connected to PLC and the concept All-in-One. For me Virtual HMI controller is sutable for new Unitronics product (Unistream without real HMI).
  23. Panel V430 has single ended 24VDC encoder input. Your encoder use two wire for "A", "B", "Z" signal == A, A- ; B, B; Z,Z-. This signal in standard encoder offer +5VDC level. Encoder nameplate parameter(model numbers) needed for correct answer what type of encoder output present. If outputs offer 24VDC level you can do the program and test encoder properly to see if A and B channels are working ok. If 5VDC - you must use encoder interface converter like https://www.kuebler.com/en/products/transmission/signal-converters/product-details/PW_1D-1D
  24. I'm not sure that it will be useful. But after an experiment on measuring temperature by SI 14 noticed that the SI 13 also reacts to temperature changes. however, it shows somewhat higher values. Maybe this is undocumented temperature channel (run on V1040) In order to get the temperature, it is necessary to operate with a SB14 bit. Therefore, the recalculation C into a F with one rung should not be a problem.
