The "Manual mode" mode represents the simplest way of inserting
tabular values into a configured software package. However, it is
comparatively time consuming as data has to be manually entered or
taught-in from the program.
After the TAB or TAB_D has been correctly configured, the tabular values
can be entered one after another. To start off with, the table size, i.e. the
number of value pairs (=points) should be specified at input NP. If the
table is to be saved in the SAVE area, then input SAV of the must be 1.
The tabular values can then be subsequently entered. In this case, to
start, the index point i should be specified at input IP of the value pair to
be entered. The X and Y value of the point should then be entered at
inputs XP and YP. In order to accept the entered value, after entering
each value pair, input WR should be set from 0 to 1. Before entering the
next point, the index at input IP should be incremented. The values for
this point should then be entered. This procedure is repeated until all of
the values have been entered.
A specific sequence does not have to be observed when entering the
individual points.
The number of entered points must match the data at input NP.
All of the entries during this procedure are transferred into the inactive
table of the and are only available after being activated in the configured
software. In order to activate the inactive table with the entered values,
input TVL should be set to 1.
After the TVL input has been set to 1, the inactive table was activated
and all table values are copied into the new, inactive table so that both
tables have the same contents. This can take some time depending on
the size of the table.
Additional changes can then be again made in the inactive table and are
only available after this has been re-activated again.
In order to output the entered tabular values, after entering the data at
input IP, the index of the point i, to be displayed is specified, and input
RD is set from 0 to 1. The tabular values of point i are then displayed at
the outputs YXP (X value) and YYP (Y value). The index of point i is
output at output YIP.
