Description
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.
Operands
Constant, timer constant
MD, MW, MB - Markers
NB, NW, ND - NET markers
nNB, nND, nND- NET markers
NET stations n
IA - Analog input
QA - Analog output
QV - QV - Numeric output of a FB
You can assign the following operands to the function block inputs that are bit inputs:
Operands

M – Markers
RN - Input bit via NET
SN - Output bit via NET (send)
N - Net marker bit
nN - NET marker bit NET station n
ID: Diagnostic alarm
LE - Output backlight
P buttons
I - Bit input
Q - Bit output
Q - Bit output of a FB
