CLICK PLC communication problems

[jsathern]

I am trying to network an advanced HMI on a Raspberry pi via modbus TCP. In experimenting in trying to network them I accidently changed the CLICK plc ip address to 127.0.0.2 . Now when I go to the connect to a plc page it cannot find the plc. It doesnt even put in on the list for an option. By the way I am trying to connect directly to the plc through ethernet. It tells me my IP address on the laptop is 169.254.6.182 subnet mask 255.255.0.0 . Now my question is how to i get the plc even to populate on the list of options OR how can I get the plc back to factory settings ie. wipe the memory without laptop. I do not care if the program gets deleted as i have backups.

Thanks for any help. If you need more info let me know and ill provide it if i can.

Hello,

127.0.0.2 is a loop back address.
If the PLC has a serial port for configuration use it and change the address. Or a reset to factory defaults normally sets the IP to something valid.

I dont know how to restore to default settings without hooking up.

Which model PLC?

I found below for an ECOM.

If you can't connect to an existing/unknown ECOM100 in a network, and the card is likely newer than 2007, by powering-down and putting dip switch 6 ON, then powering up, the IP address will be reset to all 0's.... You must power down and turn this dip back OFF for card to be able to operate properly.

Mark the ecom is for the DL0x plc not the Click series.

jsathern, I would think you could set your PC to a static address of 127.0.0.3 and then change the PLC back or get a D2-DSCBL and change it back via the serial port

Pretty sure the only way to fix this is the serial port route.

Yeah, I thought, perhaps it had some dips and the data would give him an idea.

From what I know, 127.0.0.1,2,3,4,5... are all loop back addresses. The problem will be a Windows PC will not put a packet on the wire if the destination address is 127.0.0.2. I could be wrong and a method does exist.

I think this would be the quickest route ill give it a shot. I think i tried to do this and it said i cannot use 127.*.*.* but i can try again.

PLC MODEL NUMBER:C0-12DD2E-D

Here is the pinout of the cable you will need... if you have a RJ11/RJ12 (phone connector 6p6c) you can make it yourself

https://cdn.automationdirect.com/static/specs/directsoftcables.pdf

AD sells it https://www.automationdirect.com/adc/shopping/catalog/cables/plc_programming_-a-_expansion/d2-dscbl

And we also sell it USB version https://www.plccable.com/automation-direct-koyo-usb-d2-dscbl-and-click-plcs/

We both offer overnight shipping but its a easy cable to make

Yes I tried to change to static ip of 127 and as soon as you put the 7 in it pops op an error and says 127 is reserved for loopback... I guess I will have to get a rj12 to usb cable and try that route. I do not know the settings for using serial though. I had a cable yesterday and tried to autoconfigure and it took too long (about an hour and it only tried 30/247 something ports). I was running it at work when i had access to the cable.

Also another question regarding hooking up using rs-232: If I am hooking up to the CLICK plc with a cable that is rj12 to USB, what port type do i use? The options for hooking up are Ethernet Serial and USB.

Leave everything default but the COM port number, check your device manager for the COM number

The settings below is what I use

Thanks I will give it a try when i get the cable.

I'm sure i have a phone cord somewhere. My laptop doesn't have a serial so i would have to do the rj12 to usb. I do not need the converter in the cable? i can just make a rj12 to usb cord?

No you need a RS232 to USB adapter, do you have one? if yes then make a RJ12 to DB9 and try using your adapter

I will have to purchase one. Thanks for your help! I will update when I figure it out. Do you think this cord would work? https://www.amazon.com/gp/product/B01M10UIVQ/ref=ox_sc_act_title_1?smid=A3QKIGWODAS59O&psc=1
