Hi, If V350 installed on OEM machine - in most case it is not possible to upload project from PLC. Possible solution: 1) Contact with machine manufaturer for project download to new PLC or get new PLC with preinstalled project. 2) Find new PLC with the same model # and install mainboard and I/O board from old PLC to new PLC. 3) Find V350 with working screen and use only screen as replacment. If only screen (not touch) is in bad condition - and machine program is operational - solution 2 and 3 - is reasonable. P/S. You do not specify V350 model #. You can use solutions 2 and 3 only at your own risk. You must understand that solution 1 is correct. However, if it is not possible to implement it, you must involve a specialist with appropriate qualifications to implement solution 2 or 3.

Please try to set PLC to STOP mode via PLC INFO Mode screen. Please post PLC model #, used USB cable and (or if used ) USB to RS232 dongle type.

Hi, you must enable modbus on this sensor before try to read it via PLC. Original software do not use Modbus for talk with sensor. This text from your manual. 1) Under RS-485 serial link mode, enable Modbus protocol: 5A 05 15 01 75 // Enable Modbus protocol 5A 04 11 6F // Save setting

Please use Modbus master software for PC, USB to RS485 dongle and test sensor connection. In your R.H.R config i see strange start address 10. Maybe 0 (or 1) is correct for read sensor distance.

Please post your sensor model # or pdf manual (modbus communication manual). Please post your com port configuration. Please note some sensor provide non standard modbus

Hi, unitronics forum is not official support. Please send message to support@unitronics.com If it is new panel - it covered by the warranty. Please note V700 spec below: Power Supply Input voltage 12 or 24VDC Permissible range 10.2-28.8VDC Max. current consumption 630mA@12V 320mA@24V Exceeding the upper voltage limit can cause critical permanent damage. No fuse and user servisable parts inside. All actions related to examination and diagnosis should be performed only by qualified specialists.

In my opinion, such a connection is possible. After considering the scheme of the input circuits of the VFD, we can come to the conclusion that the output current of the PNP is sufficient to turn on the IF inputs. However, you should understand that the VFD is a source of interference. Therefore, you must pay attention to grounding the VFD and minimizing the length of conductors that can cause interference. If the distance from the PLC to the VFD is significant, then you should use the relay circuit and isolate the PLC from interference that can come through the long cable to the VFD.

Please describe how you check the connection. V350 has only one RS232 port, which is also RS485 and is used to communicate with Visilogic. If Visilogic is connected, the modbus is physically disabled (PCOM protocol used). You need, at least temporarily, an additional RS232 card or ethernet card. Accordingly, as I wrote above, by adding an ethernet card, you can connect to unistream via an ethernet cable.

I recommend that you take a PLC that has a communication problem with the new firmware and downgrade the firmware version to the previous one for the test. Use an older program accordingly. If everything works properly, you need to contact support to identify problems in the environment or new firmware. If problems in the controller with a reduced version of the firmware remain, the problem is in the PLC and you should contact the distributor about the warranty. P.S. The only question is whether your machine has any new sources of electromagnetic noise, grounding or power issues with the software update. Sometimes an imperceptible design change fuels our desire to wrestle with firmwares and programs.

In this document https://downloads.unitronicsplc.com/Sites/plc/Unilogic/UniLogic_1.34.192_November_2023.pdf on p.5 - info about new firmware and new IO with specific #. Maybe I/O module firmware update needed. Please send request to support@unitronics.com.

Please send message to support@unitronics.com The old firmware needs to be updated step by step, a gradual transition to newer versions is required. Support will provide this information.

Please post display model # or pdf for this display. It is possible that display protocol is not compatible with used PLC.

V280 - standard Vision. This table must be used Then ML9 ----5109 in decimal format

ML0 ----7000hex ML9-----7009hex But you must know about different address table for Standard or Enhanced Vision PLC. Please post your PLC model

You can find modbus address table in Visilogic Help

Please read Help topic and find PTO function error code. Note error codes is different for different PTO FB. Main problem with PTO - correct configuration. Please select correct Unit and Pulses per Unit numbers. Some combination do not work - play with different numbers and different stepper driver divider (2,4,16,32,64 ...ect). It is good if you try to use the same for both channel for test. Also check Ranges, if it is not in correct ranges - no move possible. Note the minimum and maximum ranges for your motion profile. Range Minimum Maximum 1 5 Hz 15 kHz 2 10 Hz 20 kHz 3 305 Hz 133 kHz 4 610 Hz 200 kHz If it possible post your project with PTO configuration to this topic.

Try simple solution - add net with Compare FB If MI2 < 204 then MI3=0; If MI2 >=204 and MI2<=1023 then use Linearization FB (you use it in net4) ; If MI2>1023 then MI3=200 Last net MI3 stored to DW1

In this screenshot, the ratio of the number of likes for two messages is interesting. I wonder how many users who liked the first post also liked the second

Yes PLC needed No. Please find and read topic on forum with the same quastion.

You must configure machine - write needed parameters to part of project DT columns (maybe different data type column needed. Save DT to PLC write data to DT. Then configure 'Restore default' button on some settings display and create rung with restore contact -|P| - and needed DT read function. Data from DT must overwrite losted data in PLC.

You have probably not seen how many times a dead battery leads to the failure of modern equipment. This cannot be avoided because a forgetful person has to take care of it. The best day - "dead battery day" is the first day of the week after a long weekend... The most important thing for the consumer is the ability to restore the application through the SD card as mentioned above. When performing an important project, I always make an autocorrector subroutine for parameters that are critical, they are constants in the code or are pulled from the data table stored in flash. If the battery goes down, as indicated by Joe above, when the machine is turned on and an automatic warning window appears and "Confirm" button must be used. If the parameters have skyrocketed (at least one of them went beyond the allowed limits and the battery died SB8=1), then their automatic correction also generates a window that says that the battery has already died and the standard parameters are used. There is a warning about this in the user manual that I provide for the machine operator. P.S. However, one user exceeded all my expectations. After the battery failed, he did not replace it, but only entered the parameters manually (in info mode) with operands printed on paper every time the machine was turned on at the beginning of the week. This was his solution to the problem - because he was afraid to disassemble the PLC case to replace the battery.
