Set up the LevelMaster request blocks files
In order for a Totalflow device to poll a LevelMaster and retrieve its data, there must be a MODBUS
®
request block file for each
tank. This procedure creates a file to hold the data for each tank.
To set up the LevelMaster request block files:
1. Select the Request Blocks tab (Figure 49).
Figure 49: LevelMaster application request block files
2. Select Add and enter a file name for the tank this file will be associated with. If multiple tanks are being set up, assign a
unique name for each tank.
3. Click OK .
4. Modify the application, if required, to reflect the application slot instantiated previously. In this instance, the application
number is set to
51 .
5. Select the first tank number associated with the Tank Application.
6. Set Tank Number to 1 , in this instance. Additional tanks will follow incrementally after this number. In repeating instances
for multiple tanks, change the tank number and ID for each new tank.
7. Set the correct number of sensors for this tank. In this instance, a Dual Level sensor is being used.
8. Modify the ID to match the unit ID. In this instance, set ID to 1 . Additional tanks will follow incrementally after this ID
number.
9. Set the interval to the time desired between data requests. Typically, this is set to poll every 15 minutes.
10. Click Send to save the file on the flow computer or remote controller.
11. After adding each tank, click Save to save this file in PCCU to keep a copy for backup. In the Save Request File screen,
the path may read like this: “C:/PCCU32/LMBlockRequest/TankReq1.TRB”.
12. It may be necessary to create the LMBlockRequest folder shown in this example. In repeating instances, append the file
name with the tank number. For example, change 1 to 2, etc.
13. Repeat steps 2 through 12 if setting up more than one tank. Rename the file for each tank set up in step 2.
14. When files for all tanks are created and saved, proceed to configure the LCD display.
