Setting
Parameters
Ladder Logic
Explanation
Rung #0
Does an initial read of the M1 file. This is
necessary to get the sequence number for
future writes.
Rung #1
Loads data into the write location ready to
write. The data required is:
a.
Sequence Number
b.
Command Number
c.
Parameter Offset
d.
Parameter Value
Rung #2
Checks to see if the data was loaded from
the previous rung, then writes to the M0
file.
Rung #3
Reads the M1 file for the response.
Rung #4
Checks the results of the read to make sure
that the sequence number was incremented
(write complete) and that the status is zero
(no error). If the check is good, it latches a
bit for the next parameter.
Rung #5
Checks the results of the read and if the
status is not zero (error occurred) restarts
the process of writing this parameter.
Rungs #6-30
Duplicate the same process as rungs
#1 to #5 for the remaining parameters.
a.
Rungs #1-5 - Units
b.
Rungs #6-10 - Number of Averages
c.
Rungs #11-15 - WAVERSAVER Set-
ting
d.
Rungs #16-20 - Zero Tolerance
e.
Rungs #21-25 - Auto Zero Tolerance
f.
Rungs #26-30 - Motion Tolerance
