With this response, the sequence will start depending on two parameters:
•
Lookup Table yz Input X-Axis Source
Object 3yz0h and;
•
Lookup Table yz Auto Repeat
Object 3yz2h
By default, the “Auto Repeat” object is set to FALSE (0). In this case, the lookup table will
react in the following way:
The X-Axis control source is treated as a digital input. When the control input is ON,
the output will be changed over a period of time based on the profile in the lookup
table. Once the profile has finished (i.e. reached index 11, or an
‘Ignored’ response),
the output will remain at the last output at the end of the profile until the control input
turns OFF.
However
, when the
“Auto Repeat” object is set to TRUE (1), the lookup table will react in
the following way:
When the control input is ON, the output will be changed over a period of time
based on the profile in the lookup table. Once the profile has finished (i.e. reached
index 11, or an ‘Ignored’ response), the lookup table will revert back to the first
point in the table and Auto Repeat the sequence. This will continue for as long as
the input remains ON. Once the input turns OFF, the lookup table sequence will
stop and the output of the lookup table is zero.
Note:
When the control input is OFF, the output is always at zero. When the input comes
ON, the profile will
ALWAYS
start at position (X
1
, Y
1
) which is 0 output for 0ms.
In a time response, the data in object 3yz8h
LTyz Point X-Axis PV
is measured in
milliseconds, and object 3yz3h
LTyz X-Axis Decimal Digits PV
is automatically set to 0.
A minimum value of 1ms must be selected for all points other than sub-index 1 which is
automatically set to [0,0]. The interval time between each point on the X-axis can be set
anywhere from 1ms to 24 hours. [86,400,000 ms]
