Function Code 9 – Analog Transfer
GENERAL DESCRIPTION
This function selects one of two inputs depending on Boolean input . The output of
function code 9 equals the input determined by the state of input . There are two
time constants to provide smooth transfer in both directions.
UTILIZATION
The MOD 30ML/MODCELL compound FC9 used here has a combination of EX
function blocks (Expression block) and Timer (TM) blocks.
Figure 9 .1.
Function Code 9
The Expression block S1/S2 has input called S1,S2 and S3. The two inputs for the analog
transfer are connected to the S1 and S2 inputs. The transfer signal or the select signal
(Boolean) is connected to the S3 input. The result of the EX block FC9 is the final result.
In the TM block (timer) S4, enter the transfer time for the input S1 and in the TM block
(timer) S5, enter the transfer time for the input S2 in milli-second time units.
