Description
Note
I2
Analog value 2 for storage
I3
Analog value 3 for storage
I4
Analog value 4 for storage
If too many log entries are made in a short amount of time,
some of the entries may be lost. An important factor to con-
sider within this context is the speed of the memory card being
used. If logging is triggered via function block inputs T1 through
T4, this problem can be avoided by only having one save oper-
ation be triggered if the function block is not in the "logging dis-
abled" state.
Assigning operands
You can assign the following operands to the function block inputs that are numeric
inputs.
