Chapter 4: Parameter passing
61
In SG2, almost all the function block can use other function block’s current value as its preset
value. This process we called data transmission. This chapter will describe some regulation about
data transmission.
SG2 inner data type
All the data stored in SG2 inner system are integer. Even through some parameter likes “A01
= 9.99V” display in LED, in fact “9.99” stored in SG2 inner system is “999”. Only in display
stage, the decimal point of “9.99” added according to its physical significance.
When analog
variable and other function block current value passed to other function block or analog
output as preset value, essentially just integers passed. When need to display those passed
integer preset value in LED, decimal point will be added according to physical significance.
Example1:
A05 current value passing to other function block as preset value:
When A05=2.34V, A05’s inner value 234 is passed to other function block as preset value.
Passing to AQ01 automatically as 2.34V, Passing to B001 (G01) automatically as 2.34V, Passing
to B002(T01 time base is 0.01s) automatically as 2.34s, Passing to B003(T02 time base is 0.1s)
automatically as 23.4s, Passing to B004(T03 time base is 1s) automatically as 234s, Passing to
B005(C01) automatically as 234:
