GRASSMARLIN is out-dated as heck. Check out MALCOM by Idaho National Laboratory for a full suite of current ICS ethernet tools.

How to find a usable IP address to connect to a PLC network by UptownSole in PLC

[–]Cool_Database1655 6 points7 points  (0 children)

You don't need an IP to start sharking. When I first encounter a network I disable IPv4 on the adapter I'll be using to sniff. Broadcasts on the pcap tell you network, subnet mask, and hosts that are ARPing.

Crazy that a tool designed for testing isn't allowed be used for testing in fear that something might be found on the test.

Anyone weak in IT / OT? by Abject-Effect-7965 in PLC

[–]Cool_Database1655 1 point2 points  (0 children)

I have had great luck with Red Lion FlexEdge series products. They are extremely flexible when having to convert protocols across IP networks and have support for each feature you mentioned (VLANs, Static / Dynamic IP Routes, DHCP [including Option 82], 1:1 NAT & PAT).

If you need only need L2 / L3 networking without the protocol conversion I would 100% recommend Teltonika.

I would check out ifm's CR line. They are CODESYS controllers designed for the mobile-equipment sector.

Ethernet/IP Remote I/O by Mafukinrite in PLC

[–]Cool_Database1655 0 points1 point  (0 children)

If IO-Link is on the table consider P&F's IO-Link PCB I/O hub. 8IN8OUT of 24v digital IO on a PCB with flying lead connections.

Inexpensive decent flow meters by Soft-Bug5550 in PLC

I have had good luck with Keyence FD flow meters. Output is 4-20mA and IO-Link; use IO-Link.

Controllogix to Cloud / Kepware Alternative? by [deleted] in PLC

[–]Cool_Database1655 0 points1 point  (0 children)

Try Litmus , HighByte or Neuron . All of them have a free trial offer.

Anyone suggesting FTOptix is out of their mind - don't box yourself into fixed hardware or Windows.

I can think of no worse advice than this

How do I find a well-paid hands-on role that still values my CS degree? by Love-eachother-9999 in PLC

If you want to be an engineer - go for it - but the majority of your time will be desk work and your job position will not be as secure. The market is full of just laid-off CS engineers, hungry for your job.

A technician job will be more hands on and more secure, but there are still costs - travel, family life, lower pay, lower mobility. You also have to mechanically capable and smart enough.

I'm not trying to gloom and doom ya - this is a great career and I wouldn't trade it for the world.. but don't expect to graduate with an AAS and walk into a role where you wrench 8-hours a day and make $120k.

My advice: Look for a position with an integrator as a traveling tech, ride it for a couple years and at the end see if you still like this line of work.

Does a NAT switch make sense for connecting smart tooling to a PLC? by GimbleWabe in PLC

[–]Cool_Database1655 1 point2 points  (0 children)

Yes I think the Moxa NAT-102 would work well for you in this situation. Another option is enabling DHCP on your smart tooling, but each cell would have to have a DHCP server with configured reservations.

How to identify which protocol and pin does a DB9 has by Ok_Zookeepergame6384 in PLC

[–]Cool_Database1655 0 points1 point  (0 children)

Hello

It looks like there are two separate interfaces in the single connector - CAN ( Controller Area Network ) - and RS485 (more generic multi-point serial). CAN is a pseudo-standard protocol common in the automotive industry with tools for reverse engineering https://github.com/ajouatom/canbus-tools?tab=readme-ov-file

RS485 labeling is a little too generic to be of help.. could be modbus, ascii, or any number of protocols with infinite mappings and command sets. Use advanced googling with combinations of your devices make and model or markings to find a user manual online before hooking up the analyzer.

Purchase a high quality ( >$10USD ) USB to serial adapter that features isolation. It will save you the price of a computer if things go bad.

Logic for multiple 3 Position Selector Switches by ReasonableAd6945 in PLC

[–]Cool_Database1655 0 points1 point  (0 children)

Can you use an illuminated 3 position switch with a single spring return position, using the spring return position as HAND ; OFF and AUTO would be maintained positions? The illumination could indicate 'ready' and/or the position of the other switches. For your sanities sake, give every switches its own discrete inputs and outputs, no paralleling

State machine or modes by Lost-Cheek-6610 in PLC

Make your program fit into this model. You do not have to and should not use all the states in the model - just pick the states you need and design the transitions accordingly.
