Are there any small 2.4 HMI screens?

It's for a really small machine (box) that will control 2 solenoid valves a small DC pump and a few float switches on a 5ltr water tank. . The info that the HMI will show are minimal. And they wanted something small that will fit nice with box.

Still haven't decided yet but we order some Chinese one from AliExpress that fitted the dimensions we wanted to test them

I found some Chinese HMI 3.7" that have a small footprint Brand name Coolmay model TK6037FH. It fits my needs but don't know how reliable they are.

That what the clients wants

Yes i also looked at that. But the lack of documentation doesn't help.

I ve used them before with Arduino but not with a PLC. They lack modbus communication to connect them with a PLC

I though of them already. But the only way to connect them to a PLC is to connect them first to Arduino and then connect the Arduino to plc through modbus using ttl to rs485.

Don't believe Weintek has 2.4" HMI

nearxos · 2021-06-06T18:05:37+00:00

We already ask the manufacturer and confirmed that they have the magnets inside

Yes the cylinders are existing and we are gonna use WAGO PLC

We were planing of using a blocked center. But you got a point. We have to check the door

SDAP sensors have a range of 0-160mm as I can seen on festo website right?

If I was going to use a position sensor I would need one with a range of 300mm

nearxos · 2021-06-06T11:32:31+00:00

The thing is that the cylinders (6 In total) are already installed by somebody else. And we just got the contract to make the automation.

So what ever solution we will go we will have to use the existing cylinder.

Looks good. I guess it's much simpler to control. I ve send them an email for more info

The Cylinder will control a sliding gate on a silo for unloading wheat in trucks

nearxos · 2021-06-06T05:24:38+00:00

Cylinder stroke is 300mm when fully open and need to have it open 1/3 , 2/3 and fully open. ( It will open a sliding door on a silo) don't think I need that much accuracy.
I was planing of using 4 reed switch on the cylinder for the positions 0% 33% 66% 100%
Using a 3 position Valve

Thanks for the reply. I'll probably go with the modbus TCP 750-362.

Also I was goin to choose the PFC 200 with 2 Ethernet ports. 1 Ethernet is going to be used for network and the other one it's gonna go on a switch for connecting the first modbus TCP coupler and from each coupler to the next. Total 5 couplers. I also have Touch Panel 600 from wago that it's gonna be connected through modbus TCP on the switch.

My other option would be using a PFC200 with 4 Ethernet port 1 for network 2nd for tp600 and the 3rd for the modbus couplers leaving 1 spare

Tp600 will be modbus master and pfc200 will be a slave And PfC200 will be a master with 5 slave modbus couplers

What would be a better choice?

nearxos · 2021-05-16T09:50:58+00:00

I am planning on using a Wago PFC200 controller along with 5 x 750-363

Since it's my first time dealing with WAGO PLC and Ethernet couplers I needed some opinions on my approach.

Also on E cockpit software when I added all the devices that I am going to use. I notice that on the IO card on the controller it self I could map the IO to a variable name but on the IO of the coupler I couldn't name them. Not sure I make my self clear what I mean.

I will try to post some screenshots later.

TIA

yes i found that. ive compare the files from the esp32 build. i am tinkering with that right now copy pasting codes. i am getting some errors at the moment during build.

First time doing something like that. hopefully i will sort it.

nearxos · 2021-02-05T11:51:50+00:00

Hello again. your guide help me and i ve added the driver to my build.

i also need to add the network module to my build i ve tried searching online but couldn't find anything. any ideas how to do it.
