  1. TLB have internal CONTINUOUS FAST WEIGHT TRANSMISSION PROTOCOL 300Hz weight data with minimum baud rate 38400 baud over RS485 provided. I think - you can apply Protocol FB and read weight in 1 read per scan rate. As you use Ethernet for visilogc connection - you have free PORT1 on V430. It is simple and fast solution. Another net solution has faster transmition (CANopen for example), but comm command not possible to place inside interrupt routine. Than real rate not faster than 1 per scan. I test CAN open servo drive position readout - 1read per scan works - faster maybe possible but i cannot test CANopen readout with interrupt.
  2. Is it all speed of 90VDC motor needed in application? Maybe 48VDC or 24VDC operation is possible without any problem with approx 1/2 or 1/4 speed. Than standard PS can be used.
  3. You need small power supply. But CBC-801 is non isolated triac rectifire with fixed output voltage. Then user must to use well isolated selector switch for motor or use isolation transformer (if moisture present near system). Is it isolation transformer present in original diagram for power DC motor?
  4. It is small 1.5x2mm bga chip. It is not possible to simple replace chip . Reworking hardware and some expirience needed. Than maybe you can ask local distributor for base board replacement (if it possible).
  5. As for me - you must use two 48VDC standard AC/DC power supply. On standard PS present voltage correction pot. Then you can easly set 45VDC on both. Then (45VDC)+(45VDC)=90VDC. But max current of PS must be sutable for used motor. Retrofitting with standard component - best solution. https://www.amazon.com/MEAN-WELL-LRS-350-48-350-4W-Switchable/dp/B013EU4KNK/ref=pd_day0_60_1/145-3497793-0204455?_encoding=UTF8&pd_rd_i=B013EU4KNK&pd_rd_r=9fdb6611-0c8e-4ee6-a25e-acc2717c9e2d&pd_rd_w=54shm&pd_rd_wg=InXWl&pf_rd_p=ecf748b5-e796-4a0d-9a46-406a973ba8da&pf_rd_r=NEYJ49BF0DF7CC8FMJ0T&psc=1&refRID=NEYJ49BF0DF7CC8FMJ0T Or you can use DIN rail mount PS.
  6. This is probably not possible without changing the screen. However, I usually select a place at the top or bottom of the screen - where with the help of a list of pictures or a list of texts i implement tips for the operator. If this tips are not active then this place either has a background color or is hidden by the Hide command. It's fast and convenient.
  7. As follows from my observations - the main problem is the appearance of condensation in the panel due to lack of temperature control in the control box. Also, a person in such productions very often washes everything around and water gets into incorrectly installed panels. Sometimes I see that the panel when turning on in the morning has fogging in the middle - this is the first sign that there will be problems in the future if you do not take appropriate measures. I only got one panel 7' with a faulty board (faulty touch panel controller). Unfortunately, I could not establish the reasons why it stopped working. The touch panel itself was not damaged (tested by connecting to a working board).
  8. You can masure this time via Utils/Debug/Interval (Start-Stop).
  9. There is no button inside. https://www.shanpu.com.tw/en/product/tags/1/Rotary-Encoder-switch But only 10VDC sample present...
  10. This type of encoder has no electronic part inside - then only 2 contact with common wire for AB signal and NO contact for button. 10mA 5V signal provided. As we see in US5-B5-TA30 - Input work with 24V 8mA max signal. Then you can use it for US5-B5-TA30 PLC but contact life is hard to predict. As for me - this type of encoder used inside of device mounted on pcb with minimum wire length to 5V powered MCU. Then better solution - use industrial grade encoder 24VDC rated and IP65-67 design.
  11. The main problem with Ehternet card after installation - insert Ehternet cable to Ehternet connector! Many times i found some installations where Ethernet cable connected to Expansion connector by mistake. And no connection.... V700 - is the champion in this type of mistake.
  12. I use two timer (0.5-1sec and 3-5sec) powered by button contacts. Increment block is operated by: -|P|- for button -----> one increment, -| |- for button and -|P|- for SB3 (1sec pulse) and -| |- for timer 1 (0.5-1sec) ------> 1sec increment, -| |- for button and -|P|- for SB7 (0.1sec pulse) and -| |- for timer 2 (3-5ec) --------> 0.1sec increment. Than single tick, slow and fast increment with ajustable changover possible. If use -|P|- and -|N|- for SB3 - increment time is 0.5sec. If user need to change many values - this method is use only two timers for all increment-decrement operations. User only must to operate this timers via needed buttons.
  13. In CNC machine external hardware WatchDog is used for power off machine if something wrong happend. In your case you can write some code for generate cyclic watchdog reset signal on some Unistream output if MQTT is OK. This signal can reset external 24v powered NC timer (best way to use timer with two setpoint that generate power off and power on to Unistream +24V power supply) . You can also use another output to bypass external watchdog timer if user do not use MQTT and do not need to restart. Or if restart happend to many times. One problem - set timer setpoint correctly - Unistream must have time to restart MQTT and generate watchdog reset signal.
  14. Then, on power off state,check - is the IC output shorted. If not, You can try to replace IC.
  15. It follows from your story - the legs are the main enemy of the brain. Anticipating a 4 hour walk, the brain found a solution. The PLC developers had the same opinion and therefore made automatic address switching in case of a conflict. Today I saw how remotely Unitronics support can fix the Unistream brain and it also made an unforgettable impression on me. The main thing is that as a result everything worked. Therefore, I congratulate you on a reasonable solution to a complex remote task.
  16. Unitronics support help to solve issue via remote connection. After that, according to the recommendations i download blank project and panel restart to normal mode. Thanks to the Unitronics support for a quick solution!
  17. Please check 24V voltage power supply on broken analog output installation. I case great overvoltage (5-6year power supply can do little joke) >>>28V - linear power IC (78M15) in smd package can desolder himself....
  18. I don't know how experienced you are in electronics. However, if you have a digital voltmeter, the only thing you can check is the 15V supply voltage of the analog output chips. There is a 78M15G chip on the I/ O board. Find the instruction for this chip and measure the power supply at its input (should be 24V) and 15V at the output. (Any quastion in PM). It is clear that all actions you take at your own risk. Probably the only thing that can be advised in your situation. In my experience, there have been cases of failure of just such a chip in different device. However, a qualified electronics technician must repair and change something in the circuit (even such "big" chip). The best way is to replace the PLC with a new one.

And p.102 about write. Please check registers that you mark in your previos topic. Some of them may disable external request to slave. SIemens use system of binector for configure signal flow inside the device. Please check via Siemens software signal flow from Inputs and to outputs. Sometimes user must to define control sorce...
  20. No, screen react only for 0.2-0.5sec. and i can only change System, Network, Utilites menu but no information prsent. Connecting frame run on screen. UniApps start not posible. All touch is interrupted by Connecting frame. Also try with mouse... no result.
  21. USP -070-B10 panel used as VNC client started with black screen. I prepare recovery DOK with 1.28.58 firmware as this version it used for program PLC with the same panel+CPU as server. After sucessfull recovery - USP -070-B10 show Connecting frame and do not connect with server PLC. I try to disable VNC client mode but as i see it is not possible. Connecting frame still on screen. I can select System, Network, Utilites at time approx 0.5 sec after start and Connecting screen lock all function. Machine work with server PLC but remote panel do not work now. Maybe something wrong with settings now but i can't chane it. Unilogic say Download and Online mode are not supported for USL and Unistream PLC's acting as ones. Any idea? Maybe i lost something in manual or help? How to disable VNC on USP? P/S Change firmware for another version do not change panel behavior.
  22. Maybe fastest way to build this type of application is using FB Drum sequencer. Please read help topic about this FB and try to run this idea in Samba. Simple place checkbox for needed MB and run outputs via this MB. Please open Drum example projects in visilogic Help menu - you can easly implement one of them for your hardware.
  23. Hi, try this checklist: - wire swap A & B; - check - is it V700 and Energy Analyzer correct in master-slave mode; - configure com port and disable all modbus send net. Connect V700 A&B wires to PC - Energy Analyzer RS485net. Go to info mode and try monitor RS485 packets via V700 com port. If you see something correct than port and speed connection is OK. - try to activate Modbus and check via Info mode - what is go from V700 and from Energy Analyzer; - try to use single Modbus command activated by button and check Modbus status. As i see you try to read MF 44 direct via modbus. On forum is present topics with Energy Meters float read via Modbus issue - maybe in your case some tips and tricks with two MI to MF convertion needed. Please post Energy Analyzer model.
  24. I have 1210 with the same behavior (but via standard connection). After some time (approx half year) PLC start with black screen and beeps. After some investigation (with Unitronics support) found problem in grafic chip soldering. After resolder chip - all ok. Maybe it is not the same issue... If Ldr 0x000001B0 code is the same in all Stop Mode cases - please check it via Visilogic Find Subroutine By Ladder error code in Edit menu.
