There are the methods below.
|
|
1. |
In order
to change to [Enable I/O (*1)]
on the logic program, turn on the 7th Bit of the system variable, [#command].
Then the state will change to [Enable
I/O]. |
2. |
Go to the
menu on the LT Editor side,
[Controller] ->[Setup] and on the
setting screen, check [Enable I/O]
and download the logic program to the
LT again to enable it. When
the LT Editor is in Monitoring
Mode, on the setting screen the check
box of [Enable I/O] is not displayed.
Set it in Programming Mode. |

|
|
*1 [Enable
I/O] |
This function
enables the inputs/outputs to the LT main
unit and external I/O of the I/O unit. In
normal operations, the input/output of the
external I/O is disabled when the LT is set
to the RUN mode after performing a Logic
Program download. For safty reasons, this
function prevents the possibility of accidental
startups of machines caused by errors in
operation and logic programs.
Therefore, in order to perform the input/output of the external I/O, it's
necessary to make the state [Enable I/O] with the following two methods.
|
(1)
Set [Enable I/O] every download of a
logic program.
*Downloading
the logic program again returns the setting
to the original.
