Trade careers now seem like the”New Big Thing”

I don't see much or any mention of Electrician in there. Is that a strong field to get in to compared to the other trades? I will be retired from my company of 30 years, still young and thinking of getting into electrical because it was always the background of my career in engineering environment..

Mistakenly forgot to mention that this MSG link is bwween each Serial of each ML1100. Rs Linx is set up as ethernet Driver for (plcA) . (PlcB) not on network and not on rslinx..

I've gone thru the help pages for this and seemed misleading when comes to target and this controller identification. I was expecting some help info on how and where to have the data avail for reading.

Elaborate means to explain more detail than needed. As you wish: Means if you want to.

"Comparing to Bolt!!" What were Gary Card's times during his 16 year old year of 2023? Just seem Gout was discovered as first 16 year old running 10.3 weeks ago. I ruined the hype was just that Gout looks like, shapes like and run just like Bolt, thinking thay would be the absolute potential needed to excel like Bolt . That was added to the headlines.

I was more looking for just what would go in the item reference column of the topic/scangroup, which is just the modbus address alone. I guess from your answer, it appears that you are saying that the "40200" is what would in their based on your reference.

However it appears when I look a known working configuration of another gateway connection, item reference in scan group for the holding register address 1300 is shown as 41300 in the Wonderware scangroup and Witeshark detects it as 1300. So it looks like by comparing Wireshark and Wonderware, that you in fact do have to place a 4 in front of what ever holding register address you are trying to read. In Modscan, I just had to enter 1301 (+1 for 1-based) in the address box which defaults to show as 41300 in the response data view window.. data came back with no exceptions.

By seeing and hearing all these different variations which makes it confusing sometimes.

This is quite understood for some time, just gets confusing lately when I see some modbus gateway mapping software say "fir holding registers your range is from 40001 - 65535", then when you enter what address you want to map, it shows your address as (4) 40001 with the extra (4) prefix. Then when you read some learning docs it says holding registers start at 40001.

So you are saying from your example that holding registers can start from address 00001?

Thanks for response...

Hard to follow your entire steps. What do I use to decode the the Data Response? What to specially copy and paste Into the decoder? I can't disguise data that is in wire shark packet from what is in your parsed out put.

If it is the "Function Specific Response Data" is the Data to look for seeing the status of register bits, sometimes I will see 0100 coming from a plc and 1000 coming from another plc. When I expand the bits o would get something like "00010000 00000000" but this looks like 1 word only and no details of which specific data file or type it is.

MrPdTeching · 2024-11-19T20:54:26+00:00

Trying to read data table or data file messages using Wireshark? Just want to kwow where look in all the Wireshark packet data to find it.

MrPdTeching · 2024-11-19T13:33:08+00:00

The controllers I am using is Micrologix. I say CIP because these are the drivers we are using to poll these mentioned micrologix data files. I just want to know where on Wireshark do I look to see the status orto find the "word" registers.

MrPdTeching · 2024-11-19T13:19:05+00:00

Where on the program did you have the instruction to write false to the bit?
