PACTware With SM100-C(III) HART Modem - Configuration for PACTware, DeviceCare

This is a follow-up instructable that will detail the steps to get it the SM100-C(III) HART Modem to work with PACTware and E&H Device care.

General overview:

PACTware is a free software that converts HART information into something that the user can read and configure. There are three parts of this puzzle that you need to get started. (note - I'm guessing as to what each part does, but if you follow the instructions you will have a functioning interface).

The HART modem device driver - This allows your PC to talk to talk to the serial device in the HART Modem.

The COMM DTM - This is what the PC uses to talk with the HART Modem and I think defines the parameters of the HART Modem. Once you install the correct one, it will not need to be changed.

The DEVICE DTM - This is instrument specific, but you can usually get by with a generic for simple configurations such as pressure. Some manufacturers (such as E&H) encode their serial numbers in a way that generic DTMs don't always read it correctly. In that case, or if you have something more intricate, such as a flow meter, you will need the device specific DTM . Fortunately these are all readily available and free from the manufacturer.

4-20mA HART device

PACTware 6.x (other versions probably also work)

Generic HART COMM DTM

Generic HART DEVICE DTM

Process steps:

1. Install the HART modem driver that can on the USB. (Step 1 from here)
2. Install PACTware 6.x from here
3. You'll notice that there are several different distributions to choose from. They all have the same base program, but include the manufacturers DEVICE DTM library. Some of these downloads are enormous as a result. Personally, I'd rather download the smallest one and add DEVICE DTMs as needed. Regardless of which flavor you choose, you can add any manufacturers DTM later.

5. https://www.fieldcommgroup.org/pactware
6. After installation you will see that two PACTwares appear; a normal PACTware and a PACTware DC (direct connect). The DC version has more of an intuitive interface and certainly easier to understand the process, but I don't belive you can build a device library. I'd recommend starting there.
7. The FieldComm PACTware version comes with a generic COMM DTM. If not:
8. Download a generic COMM DTM
9. If I find a link to a COMM DTM standalone I will post it here.
10. Download a Device DTM
11. I typically search something like "E&H t-mass 65 device DTM"
12. DTMs are usually in the DOWNLOAD section
13. Scroll through until you find the HART DTM.
14. Note - there are DTMs for other communication standards, you need the HART one.
15. Double-click the download and install. It doesn't seem to matter where, PACTware finds it somehow each time.

In the following sections I will cover navigating PACTware and PACTware DC.

1. Connect your HART modem
2. Open windows device manager and navigate to Ports.
3. Make note of which COM port the modem is in
4. Open PACTware DC
5. Click Search Device
6. Select the previously installed generic COMM DTM
7. Mine happens to be CodeWrights HART communications DTM
8. On "Parameter" you should have see your COM port # in the Serial Interface field listed along with "Yokogawa/VIT USB HART Modem." If not, use the dropdown to find the com port you identified in step 2.
9. Click OK on the bottom right.
10. This will start the device search. If you are not connected to an instrument nothing will happen.
11. By default, it takes you to "online parameterization," occasionally the information shown is not accurate. I don't know why, but I found it best to click "Read from device" to be sure it's pulling over the current device information.
12. Depending on the Device, things tend to vary from here. However, if you want changes to stick (such as range), you have to click "Write to device."

1. Click new project
2. Click the + next to the HART Communications DTM
3. Click the + next to the device DTM you want to use
4. Click the three dots next to the device DTM that you just added
5. Click "Connect"
6. The dot next to the COMM DTM and Device DTM should now be green
7. click the three dots again
8. click "Load from device." This pulls over information from the device. *You still wont see any information yet*
9. Click on the three dots again and select Parameters -> Parameterization
10. Now you should see device identification information.
11. You will also see a new menu to select Input, Output, Hart, etc.
12. To close out, disconnect the Device DTM first (3 dots) and then the COMM DTM (three dots).
