OK, notice a few things.
1) They're mixing floating point values with INTs, but when a value is floating point, it does take 4 bytes or 2 words like I mentioned in the other post. You'll have to read what BRX will see as two consecutive registers, then view them as a real, like V0:R, or use SUBSCRIB or PUBLISH or whatever.
2) It looks as if all those registers are for you to write settings, although since they're set up as holding registers, you can probably read as well as write, and perhaps if the pump has a setup keypad or something, and those values are input there, you can read them from the PLC. But, if they're intended for writes, the pump may not honor reads, slight possibility. I don't see any real time monitoring type data, at least with the labels described. Note the upper table on page 3 is labeled "Basic Parameters Setting" and FN 2 says "When working mode is dispensing, set up register 1002 1004 invalid.", which makes those registers sound like setpoints.
3) Their word and byte orders appear to be normal. (0x426b3333 == 58.8; Page 6 Item 3)
