Honeywell TDC and Experion

I have inherited an existing Honeywell Experion DCS with TDC2000 (3000?) hardware based on MFC controllers. I am trying to understand the correlation between the physical address and the addresses I can see in Quick Builder?

My background is with PCS7, DeltaV and I am trying to build an accurate I/O list for a system I have inherited. Honeywell TDC doesn't seem to relate to anything I am familiar with.

I can see physically where everything is connecting in the panel and I can, after some digging around, identify tags (points) in Experion. What I cannot understand is how these relate to each other.

Nowhere in the Quick Builder configuration can I see where tags or devices are mapped to physical addresses but this must be happening somewhere. E.g. Analogue tags always seem to be associated with "slots" 23 and 24 however my physical cards are normally in slots 17/18. I can't see where this is mapped or if the PLC register is automatically assigned based on the card location? One of my "Boxes" has two bases and the analogue cards are all within the second base?

I am familiar with Experion PKS since we upgraded our Utility Plant from Fisher PROVOX to PKS.

Control Builder is for the SCADA part of PKS not the Experion controllers and I/O.

So perhaps the TDC PLC interface boxes are publishing TDC I/O as Modbus addresses for the Experion SCADA?

Are you using Experion as the HMI, alarming and historian for the TDC system?

Or do you have 2 separate DCS's; TDC and Experion.

What is your topology like?

I do know that Honeywell has a modernization path where LCN devices can be upgraded to Ethernet and can coexist with Experion using Fault Tolerant Ethernet (FTE).

good luck

Honeywell Experion DCS with TDC2000 (3000?) hardware based on MFC controllers: Trying to understand the correlation between the physical address and the addresses I can see in Quick Builder.

There are four MSC10 controllers.
The IO is from this range:
https://www.westernprocess.com/group/5

The front end was originally one of these
https://www.westernprocess.com/Operator-Stations
but was replaced with Experion PKS in the early 00s.

Looking at Quick Builder I can identify points and addresses for example BOX_5 PV2301 or BOX_5 DO2807 but I can't find how this relates to a physical IO address on the controller.

Thanks for your assistance.

We use Honeywell's TDC scan task for our Experion SCADA system on extended controllers and HLPIUs. They had this in the early days of Experion as an option for those that did not have the TD3000 LCN infrastructure. The addressing above is similar to the HLPIU. The analog input above would be associated with box 5, Slot 23 subslot/input 1. The card would be in a specific slot in a specific rack.

I did not work on our Multifunction controller but took a look at some literature. The pictures for your IO is advance multifunction controller which was the next in series. When they put this out it was newer hardware but they look like they kept some of the configuration rules. And made some new ones.

If I am reading the manual right, the MFC had the following rules.
The controller file had logical slots 1-16 that could handle up to 16 analog inputs, 8 real analog outputs and 8 soft outputs. The 16 slots is the key. This is similar to the extended controller hardware. It could also have a point card file with eight slots. The logical slots for the point cards would be slots 17-24. A placement rule was that you could have 2 analog input cards in a point file cards but they had to be in the 7 and 8 position. I believe this where the Experion slot 23 and 24 is coming from.

The A-MC followed the software of the MFC. The physical cards changed to a more compact style and higher density. The two 8 point cards analog cards in the MFC now was one 16 point card but it still had to go in a specific slot that they addressed as 7/8 from the MFC. That kept the same logical slot 23/24. I had a degree with twelve slot card racks. If non-redundant, the point card analog module that configs as if it was in point card slot 7/8 went to slot 4 of the base rack. And if the controller was redundant, the analog card would go in the slot 2 of the base rack.

This does not add up to your comment that you have analog cards in slot 17-18.

The A-MC combined two of the MFC cards as well. Your DO point in logical slot 28 could be paired with logical slot 27 corresponding to a MFC slot 11 and 12. In a twelve card non redundant A-MC rack this card would in slot 6 of the base rack. In a redundant setup the DO cards would be in the 7 and 8 slots in the A-MC rack.

Sorry for the rambling. Some of this is guesswork since I have not had to configure this model. A set of the old system manuals site planning and configuration forms may help. There usually is a set hiding in an engineering file room or technican's office in your plant. Hopefully it will shed some light for you.

Thanks for the help BR.

Does this make sense to you?

The documention I have does not list modules 17/18 19/20 but the cards are laid out similar.

There is an additional resource that should be on your system that can help. On the Quick Builder application a help file was installed when the original project first configured the TDC boxes in Quick Builder. It always felt a bit hidden. It has been there since at least R300 release and most likely before.

In Quick Builder, look at the menu bar. There should be a drop down HELP > CONTROLLERS > TDC. It is on our systems. There is a section on MFC and A-MC. Search for IO definition or multifunction controller addressing. It did say that the IO slots are "shifted" to start at an logical slot 17 to avoid confusion with the modulating slots that are 1-16.

Below would be what I would expect the logical experion slot addresses to be for your layout. Hope this might match some of what you have.
