Im in the process of integrating our monitoring system with a Caterpillar PL1000E, I'm having a heck of a time getting information on MODBUS TCP/IP Holding register addresses to available engine parameters in a document format. I'm hoping someone can attach that here. Thanks!

The PL1000E is configured using CatET. Under "Utilities" select "Parameter Translation Editor". After making all the configurations, a Parameter List Report can be generated with the Modbus register information.

We want to collect modbus data from caterpillar G3516A3 engine mated to a compressor ariel JGT / 4, the control system is A3.
The caterpillar panel is composed of an advisor display which displays the data around locally and the data compressor is displayed with two devices Murphy TDXM and TTD both have RS485 serial port. All this we want to lead the control room which is located about 60 meters. In total there are two compressors units that are close to each other. What do you recommend?

A PL1000E can provide Modus RS485 or TCP output of your engine data. A single unit can also provide connection to both engines. There are also third party devices that can provide this data like www.monicoinc.com

Good morning know the approximate price? required to hire a CAT technician and pay annual subscription for the use of software? PL1000E will have a manual to see how complicated it is, I only found the datasheet.

I also have one of these units that is questionable. Here are the details.
I had one installed on a yacht (C18 engines). This unit functioned fine for a while and eventually lost the PCL file. Lost, as in lost. Not there. Gone. Yeah, wierd. Had a hell of a time trying to get another one back on. It eventually took the PCL file and everyone was happy for a while. Eventually, the PL1000E lost the file again. Ok, so there is something wrong with it. CAT replaces it. The new one is a bit different on the web interface. The previous one had the ability to set the CAT data link address. We require 55 as an address. The new one does not have the section for CAT data link on the modbus configuration. So, contact CAT to find out what's up. CAT sends a tech to the boat. Tech gets there and runs the Electronic Technician connected to his serial port. He downloads the configuration as an XML file and the CAT data link address is set to 55 and the software shows data.
OK, cool. So I go to my system and check to see Data. Everything as far as configuration is the same as previous. The old PCL file has been loaded. So everything should be good, right? Nope. I have data for the STBD engine, but no data for the Port engine. I have a program that reads the data that my system should see and the first 10 registers (port side) are zeros. I get Port Trans temp and pressure, but that is it on the Port side.
One could assume that the TCP transmission of data for Modbus registers is working based on the fact that I am seeing STBD side data, correct?
One could also assume that if you change the request of data to less than the total of 26 registers, as long as the request is within that range, you would see the data returned and not all 26 registers, correct?
Or is my PL1000E unit just a pile of pretty black metal now?

Can anyone advise on how to read active event and alarm registers from the generated parameter list report in "Parameter Translation Editor" page ? I am having difficulty to read alarm and active event from PL1000E via PLC touch screen panel as master modbus poll. As, there is no direct alarm/event registers defined in parameter list report generated in *.csv file.
In the order hand, I had aslo encountered some very huge values output from PL1000E modbus data despite all the slave ID, ECM address and baudrate are correctly configured.
