OTHER F110-A VARIABLES FOR COMMUNICATION
TOTAL
- variable number 566 (236h) – 6 bytes
Read total:
The value of total read using RS communications might differ from the value that
appears on the display. This is due to the fact that the display can only display up to
seven digits ( for example when two decimals are selected for total and total has a
value of 123456,78 the display will show 23456,78 while communication will read a
“total” of 12345678 and a “total decimals” of 2).
Write total:
total can only be cleared. This means writing a value different from 0 will result in
the reply of an error message. Only writing 6 bytes of zero’s to total will be
accepted.
ACCUMULATED TOTAL
- variable number 560 (230h) – 6 bytes
Read acc. total:
A difference between the read value and the display value, as explained for
“Read total”, might appear here too.
Write acc. total:
Not possible.
When reading or writing total or accumulated total it should be noted that the used values are given
including the decimals. This means that a read/write to one of these variables should be
accompanied with a read/write to the variable that holds the number of decimals for this variable:
Example: read var. 566 for total:
Read var. 33 for total decimals and calculate the real value of total by multiplying total with
10
-(total decimals)
FLOWRATE
- variable number 572 (23Ch) – 4 bytes
Read flowrate:
The value difference as mentioned with total/acc. total might appear here
too.
Write flowrate:
Not possible.
