Kepware has some Toshiba drivers in there KepServerEX product. You can download a demo of it and see what you can do with it.
We have several Nissei vertical molding machines with the TACT controller and we have a project to interface with the machines and collect data. Thus far, we have been told that they dump a text file to a share folder, but that will not work for us.
There are, however, a few notable downsides to using polycarbonate. It yellows after prolonged exposure to UV rays, doesn't perform well around hydrocarbons, and can degrade in water hotter than 160 degrees Fahrenheit.
Hola Gabriel! Unfortunately, no. The file dump and GW script is about best you can get to interface with these machines. One improvement would be to skip the Gateway Script and have something on the file server side that can parse the file and push the data to OPCUA or MQTT. Cheers! Oscar.
Oscar, Thank you for sharing the information on how you were abele to get data from the Nissei TACT controllers. We have a similar project pending and this was very helpful insight. It sounds like we should be able to get started with basic process monitoring without the custom code similar to that which you had Nissei Japan developed, but if you could point me to where I can find information on configuring the TACT file dump that would be a huge help. If you prefer to contact me directly, I sent a request for connection via linked-in or my contact information is under the Gold Level integrator listing (InteCraft Automation).
I was wondering if you had any luck with this request that I found on the Inductive website? I have a couple of Nissei machines and have been trying to get the data from them.[/quote]
I don’t have the process documented, but I would gladly assist you with it over teamviewer/remote desktop support if you can get on the RPi console. PM if you’d be interested.
The biggest drawback is that it breaks down in the presence of certain solvents, cleaners, and alcohols. Recently, we had to rule out ABS for process rollers in a printer because the solvent used to clean the printing ink would have degraded the parts over time.
PTFE, more commonly known as Teflon, has made a name for itself thanks to its non-stick properties. It's often used to coat kitchenware but is also found in the medical and technical industries. In addition to its coveted anti-adhesion characteristics, PTFE is resistant to chemicals, high temperatures, UV rays, weather, light, and water.
For example: the share folder on server PC is: \192.168.1.100\ShareFolder\Machine111 Then how can you make Machine 111 spit out response file right at the path above when I send request file (in this case Kepware send)?
We are still working on this project for our Toshiba machines. I can only save those text files with machine data to a thumb drive, but I cannot get real time data. Are you sending the files to a network folder?
We just hooked up to Stulz (Air control system) all that had to be done was add the Modbus Module to their controller and setup the addressing and now we can control/monitor the whole air control system at one of our “POT” plants and this also allows remote connection/control.
Polypropylene is a cost-effective plastic for CNC machining or waterjet cutting services. Benefits include its chemical resistance, slippery surface, and electrical insulation capability.

I was wondering if anyone has connected Ignition to any of the following injection molding machines: Toshiba Model: EC180NV21-4 Toshiba Model: EC310NIIV30-8 Toshiba Model: EC390SXV50-17AT Toshiba Model: EC380SXV50-8 CINCINNATI Model: A07B-1530-B 003#U01 CINCINNATI Model: ROBO 110I-138 NISSEI Model FN4000 NISSEI Model FN6000 Engel Model: E-MOTION 440/200US Engel Model: TG650/300 US Engel Model: ES330-250 Engel Model: ES1300/300 SODICK PLUSTECH Model: LS180R SODICK PLUSTECH Model: LSR180EH2 SODICK PLUSTECH Model: LS180R FANUC ROBOSHOT 110I-138
I was told that Toshiba doesn’t have an OPC driver for the presses. They have the Ipaqet software to collect data from/to the Injection Molding Machines.
Acrylic has a low impact strength, causing it to chip and crack easily during waterjet cutting and CNC machining services—and, more importantly, in the part’s end-use environment. For these reasons, it’s our least favorite plastic to work with.
You help me a lot with this information. Do you have another solution (2021)? If this is correct, I am doing a similar project but I would appreciate if you could send me updated information.
Every plastic is unique, but some universal considerations should always be taken into account when precision machining plastic. Here's the quick list of rules we follow:
While most plastics are generally quicker to machine than aluminum or steel, achieving tight tolerances can be tricky. If, for example, a plastic part calls for a bearing bore with a tight tolerance, we may need to let the material rest and stabilize between cuts, slowing us down. When machining acetal, however, the material is more likely to retain its size.
ABS is high on our list for its excellent machinability and strength. It has 60% of the overall strength of the number-one plastic but surpasses our top choice in impact strength. We’ve been known to slam ABS parts on the ground to demonstrate the material’s superior impact strength to customers and colleagues!
Customers like acetal because it's wear-resistant, naturally slippery, and doesn’t expand when exposed to heat and moisture. While not ideal for parts requiring acid resistance, it's an excellent material for many other uses, including bushings, gears, bearings, and more.
Allow for stabilization and cooling when using cutting methods that generate heat, especially with tight tolerance parts
When you need plastic machining, consider one of these six materials, ranked from good to better to best. Let the countdown begin!
Hi @joseut76! I am not sure if you were able to figure out how to connect Ignition to the Nissei Molding machines; we worked with Nissei to provide an text-based interface (they would not go the OPCUA route, unfortunately) Our custom code on the TACT controller will spit out a status file to a shared folder (to track uptime/downtime and reasons, mainly for OEE) and another file with process data (Flows, pressure, etc.) We then run a GW script to parse that data and put it into tags. Not the ideal solution, but it works!
No, I have not. There are a number of third party systems for Injection Molding, but I’ve found nothing that can connect directly with Ignition. We also have a couple of Nissei machines (same issue), seems like the injection molding industry likes to keep its data to itself. Good Luck!
There is a gateway timer script connecting to the shared folders that opens the file, parses the values and writes them to tags on Ignition. Also important, is that the shared folders need to be mapped from the Gateway (inside ignition.conf), instead of Windows. There is documentation on how this works here: https://docs.inductiveautomation.com/display/DOC79/Mapping+a+Network+Drive
these signal is use the communication euromap63(file based communication ) or higher version EUROMAP77 (base on opc-ua)?
Use high-precision waterjet with HPX sharp garnet to avoid the introduction of heat and achieve precise finishes and tolerances
ABS is affordable, stable over time, and a good insulator. You'll often see it in electrical applications, rapid prototyping, electronic enclosures, and consumer goods.
We'll always choose the best material for your part, and if acrylic is the right choice, then we won't think twice about using it. However, the problem is that acrylic is commonly used for clear viewing panels when polycarbonate is likely a better option.
You would expect that of any vendor, right? No, these machines do not provide any output other than a file-based output to USB or a shared folder. They aren’t even old machines really, the manufacturer simply does not offer any standard industrial protocol options.
We are working on a solution to have the Raspberry Pi push the file contents out to MQTT directly, since we are moving our environment to MQTT altogether.
This plastic is great for many applications and is commonly found in parts for the packaging industry and electrical and equipment manufacturing. Its resistance to swelling when submerged in water makes polypropylene ideal for end-use environments like labs, kitchens, and medical settings.
Hello from 2024, I want to know you can make the machine spit out folder at the right share folder? Do you have any documents about that?
Plastics have many benefits. They're widely available, strong relative to their weight, and compatible with many modern manufacturing methods, including CNC machining, high-precision waterjet cutting, and 3D printing.
(*) We initially tried to host the shared folders on our Windows file servers, but there were some crazy file-locking issues that we couldn’t afford to spend too much time fixing…
Acetal (also known as Delrin) is our top plastic choice thanks to its machinability, high strength, and ability to hold size better than other plastics.
PTFE isn't appropriate for every application, however, as it has low abrasion resistance and is susceptible to creep, which causes dimensional changes in the material over time.
The polymers that make up plastics combine in various ways to yield numerous different materials, each with unique properties and uses. While some applications have requirements that necessitate a specific type of plastic, there are times when you may have flexibility with the plastic you choose—and there are certain plastics that are better for manufacturing than others.
Polycarbonate (PC) is a naturally transparent, pliable, heat and impact-resistant plastic commonly used in eyewear, medical devices, automotive components, greenhouses, and more. Clear PC can transmit light as effectively as glass and is a better choice for clear-viewing window applications because of its high impact strength, especially when compared to other transparent plastics like acrylic. If transparency isn't a concern, PC can also be purchased with added colors.
Machining PEEK is expensive. Due to the high cost, you may want to opt for another plastic option for your application. Still, when you need it, it's a great recyclable and biocompatible replacement for metal, and it’s compatible with CNC machining.
Coming in at number six is PEEK, a high-performance plastic often used for medical applications. This material has an operating temperature of up to 480 degrees Fahrenheit and tends to tolerate all common solvents. While PEEK is incredibly strong and possesses high chemical and heat resistance, it's susceptible to UV light and doesn’t do well with halogens, sodium, and some acids.
Hi Jose! Yes, we finally had to settle for using the file on a network shared folder. It’s not the cleanest solution, but it works, for the most part. What we did was setup a Raspberry Pi(*) to act as the file server (using Samba); we created a shared folder for each machine, and configured the Nissei TACT controllers to dump the process data (MONDAT files) to the shared folder. We also had NISSEI Japan modify the software on the TACT to spit out a “machine status” file that would allow us to detect machine up/down and error codes for OEE measurement.
Thank you for sharing the information on how you were abele to get data from the Nissei TACT controllers. We have a similar project pending and this was very helpful insight. It sounds like we should be able to get started with basic process monitoring without the custom code similar to that which you had Nissei Japan developed, but if you could point me to where I can find information on configuring the TACT file dump that would be a huge help.

Any chance of a handy-dandy tutorial for your Raspi setup? We have several Nissei presses in-house, and this may alleviate the effort of reinventing the wheel. Plus, I’m lazy… heh.
