The same procedure applies to all types of peripheral devices (printer, auxiliary display, etc. In the example, the first S means that its a weight and the second S means that it is stable. First step is to connect the RS232 convertor into the scales and connect it to your computer (Im using a windows based PC but this will work on a Mac or Linux machine as well). Repeat this for the ReadWeightImmediateRepeat tag and place something onto your scales and you will see the Weight tag increase in value. If your scale does not have a Print button, it does not necessarily mean that you cannot send weight data to a PC. Now to explain what all the tags are and how to use them , the list of tags available are: When you send a message to the scales it responds with a coded series of characters eg. Another Question: I I were to use 10 scales would each one input its values into a separate excel sheet or could I make them put all of the data in one sheet? 2 I am using Mike O Brien's HID Library to connect to digital scale, Device opens successfully then displays device attached & removed messages perfectly. RS232 cables come in two varieties called "Modem Cables" and "Null Modem Cables". Please note that some BT devices require authentication via a PIN code before communicating the services available from them.

Weigh scales often have a computer located close to them so this option is to connect a RS232 to USB adapter between the scales and the computer (PC / MAC / Raspberry PI) and use software to convert the MT-SICS commands into something that DMC will understand. 0000033913 00000 n 0000152245 00000 n If everything is working correctly, you should see the weight value appear in Excel. These statements are incorrect:" Serial ports found on the back of a PC will always be either 9-Pin Male or 25-Pin female. Writing a 1 (or true) to this tag will send a command to the scales to Zero the scales. 0000005584 00000 n Run SerialPortToKeyboard.exe and configure as follows (your COM port may be different). Note: You do not have to change any serial communications parameters in the Windows Device Manager. Writing a 1 (or true) to this tag will send a command to the scales to continuously read the Immediate weight regardless if it is stable or not. Shown above are the most common USB ports found on most scales and balances along with pictures of the connectors that fit the ports. Place cursor in entry cell for weight. Cost I really struggled to come up with a negative about this approach based on the documentation but out of the 3 options it will be the most expensive. You would need WinWedge for multiple scales. for example the weight displayed is 1203kg but its send 88,863,90 etc. Now we need to create an application that converts the MT-SICS commands and responses into an OPC UA server. Almost all PCs built in the past 10 years that have serial ports will have 9-Pin male ports and usually only very old PCs will have 25-Pin serial ports. 0000006522 00000 n 0000148102 00000 n 0000006411 00000 n PDF Setting up the OPOS Driver for Retail Ariva Scales - Mettler Toledo 0000007495 00000 n Connect a Mettler Toledo 8213 - Plugable Support Mettler Toledo Balances that support the "METTLER TOLEDO Standard Interface Command Set" (MT-SICS) are able to enter results into a Custom Data Entry cell via Mettler Toledo's Serial Port to Keyboard Software.

Now configure the scales so that the interface is in "Dialog" mode and not "Print" mode . Integrating Mettler Toledo Weigh Scales to SAP Digital Manufacturing Mettler toledo MS204S Manuals | ManualsLib For example at 19200 bits/s the maximum cable length is 15M, at 9600 bits/s its 30M. 0000085254 00000 n Tip: The Scale Type box may also list additional scale types that you have added. One stretches a spring and the other bends a load cell. 0000101814 00000 n 0000129584 00000 n Writing a 1 (or true) to this tag will send a command to the scales to reset the scales, the scales will reply with the serial number of the scales. Modem cables have the wires in the cable running straight through and Null Modem cables have the transmit and receive lines crossed in the cable. In my case it was node mtserver com5 19200 as my serial port was com5 and the baud I set the scales to was 19200. 0000009323 00000 n Step 3: RS232 to USB Converter Cables If your scale has a RS232 port but your PC only has USB ports, you can purchase a RS232 to USB converter cable at any computer or office supply store for under $25.00. I already set the parity to even, data bits to 7 and changing baud rate but still the data it send to pc is different from the weight displayed in scale. Thanks for reading this blog, the next one will be released soon. Now configure the Baud rate (Speed) of the RS232 to be as fast as possible (19200 in my case) Please note that the length of the RS232 cable effects the reliable speed of communication. So the first challenge is how do I get the data from the scales into the corporate network so that it can be passed to DMC, so far I can see 3 hardware options. I have also contacted the appropriate product owners in SAP and support will be added to the development back log so watch this space. This will download the finished server from my github repository into your directory. In this example, we will use a product called BC-Wedge from TAL Technologies, Inc.. 0000004485 00000 n But only runs OnReport for about 20 times initially After Inital approx 20 runs on OnReport it never runs again, unless I remove usb cable and re-connect.
