You need to establish a working serial connection between the HMI and the VFD regardless of the equipment’s brand. That means correct interface and protocol settings. HMI and VFD communication ports should have same settings (but different addresses) in order to communicate each other. Each VFD capable of RS-485 control has a set of control registers. By writing pre-determined values to those registers, VFD starts, accelerates, decelerates, stops and other functions. All control registers, their addresses and possible values are described in the manufacturers’ manuals. You should create screen objects that write and read those values to/from the control registers of the VFD. Some registers are writable and readable (for RUN and STOP commands for example) while others are read-only (for status and alarms for example). Steps are identical regardless of the brands. I don’t work with Weintek but it is all the same.

As long as I know any actions related to passwords breakdowns are not allowed here at the forum. If there is a password on the PLC that means there is a copyright on the program inside. That is the main purpose of the password. I suppose the site admin could take a stand on the matter, but I think it is forbidden. Anyway the problem that started your topic was solved.

You’re welcome! Working equipment (the correct software and adapter and the proper PLC) should establish the connection at once. PC to PLC RS-232 or RS-485 connection is the most easiest thing when the proper equipment is held.

I don’t work with LS but I could suggest you to work only with the brand’s original equipment. I have had the same problems with my brand and solved them by using an original adapter. As far as I can see, the converter from the link is universal and there is no guarantee that it can work with your controller. It could be possible that pin arrangement of the USB to RS-232 converter is different than the PLC’s port. If there is not an autodetect function of the software you may not coonect as well. There may be other reasons related to a wrong converter.

DELTA PLC - not support for current model type or firmware version
IvanBratanov replied to pjw's topic in Other PLCs
In case everything with the RS-232 or RS-485 converters used is OK, you should also check the firmware version of the PLC. If there is an older PLC you should find an older version of WPL for example. -
DELTA PLC - not support for current model type or firmware version
IvanBratanov replied to pjw's topic in Other PLCs
You should check if the communication settings of the software are correct (model type in particular). Other reason could be wrong PLC MPU inside the package (aftermarket PLC board inside an DVP12SА package). I have had such cases. You may also have such problem if using improper USB<->RS-485 converter. -
pturmel liked a post in a topic: thumb wheel switch

Its widely used even today when for example large quantity of 7-seg numbers have to be driven by limitd number of PLC outputs. Each number is illuminated for a fraction of second with its value, then the next etc. When the last digit is illuminated it starts back with the first one. Because of the high switching speed all the digits seem to be illuminated at the same time for the eye.

What is this Delta AS2 PLC? Never heard of it. Do you mean AS200? Perhaps the first network is Modbus?! If so then both networks communicate in different languages. The modbus master is the Delta HMI. Moreover there is no way for the modbus slave (the Delta PLC) to send data to the Siemens PLC through the same modbus network because as slave it should only respond to the Delta HMI master. So you have to use another COM port of the Delta PLC for the communication with the Siemens (i.e. to create another network). Furthermore you should use some kind of a gateway to translate data to the Profibus. I don’t work with Siemens and I’m not familiar with Profibus, but I think that there are a lot of obstacles. You should do hardware changes anyway. There is something else. First you are talking about Profibus, then about Profinet. As long as I know Profinet is Ethernet-based and Profibus is serial communication. Furthermore I’ve never heard about Delta HMI with a Profinet interface.

IvanBratanov started following thumb wheel switch
-
First you have to find out the thumbwheel switch output’s coding system (binary, decimal, hexadecimal). Then you have to find the output’s polarity (common anode or common cathode) in order to connect it proper to the PLC’s inputs. Each digit of the thumbwheel switch has 4 outputs. So you have to use inputs X0-X3 of the PLC for the first digit, X4-X7 for the second digit etc. For the first digit (if the thumbwheel switch has binary outputs) you may use MOV instruction in format with Kn value to modify the input values: LD M1000 MOV K1X0 D0 The instructions above will continuously convert the states of the X0-X3 inputs and store the result in D0. So D0 will contain the first digit of the thumbwheel switch (if the first digit of the switch is 1, the value in D0 will be 1 as well). The situation for the other digits will be similarly.

In order to have a working HMI<->PLC serial communication you should have: 1) 2 Modbus nodes supporting same communication interfaces, formats and baudrates 2) correct interface cable (Delta is selling communication cables). I personally make the cables myself, but I have a lot of experience with Delta. 3) correct settings of both nodes (If HMI is set to RS-232, ASCII mode, 7, E, 1, 9600BPS for example, the PLC has to be set the same way) 4) different communication addresses (if HMI is 1, PLC should be for example 2) 5) correct screen object target register address set in the HMI To do that you should set correct both devices. In DOPsoft still when choosing the HMI model the Project wizard is opened where you can choose which port at which interface and communication format to set. The communication addresses of both devices could be set there too. If you're working with WPLsoft, there is an option to set both COM ports of the PLC with the Communication program wizard. I don't use ISPsoft, but as long as I know the COMMGR is used there for the communication settings. Every HMI screen object target register address (write or read) should point to proper register address from the memory of the PLC. For example if you want to turn on PLC Y0 output from the HMI you should use Set to on button which target address should point to the Y0 thru the communication link. Setting a working serial communication between DOP-107BV and DVP-SS2 is the most easiest thing when all conditions above are met. I'm using the DVP RS-232 port only for program upload/download/monitor/online edit actions. The RS-485 of the PLC is much suitable for HMI<->PLC communications.

Hello, I'm using Delta DVP in my projects but never heard about recipes there. Recipes are available in Delta DOP HMIs, but not in DVP. Perhaps there are some in AS series but I don't use AS.

DopSoft-Delta hmi- screen changing without button
IvanBratanov replied to SHAY's topic in Other PLCs
You might first check the screen change method you've selected in DOPsoft. If you choosed a control block register for the screens to be changed by, then the problem is in the PLC's program. -
[Solved] Inovance IT5070T HMI - unable to upload project.
IvanBratanov replied to IvanBratanov's topic in Other PLCs
I contacted the manufacturer. It seems that the program is banned from uploading at all. That's why it doesn't want a password. -
Hello! I'm unable to upload project file from an Inovance IT5070T HMI: The software used is Inovance InoTouch. Connection is USB. When I try to upload the upload the project file from the device the result is this: Certainly there is a project file in the HMI. Why does the software say that file does not exist? Thank you!

Take look at this manual. I'm not familiar with Panasonic, but E45 is described here.
