Notes for using a customizable logic
A customizable logic performs processing every 2 ms in the following sequence.
(1) At the beginning of the process, latch the external input signals to all customizable logics in step 1 to 10
to ensure simultaneity.
(2) Logical operations are performed in an order of steps 1 to 10.
(3) In case the output of one step becomes the input of the next step, the step output, of which output is
highly prioritized, can be used in the same process.
(4) The customizable logic updates all of the five output signals simultaneously.
Fig. 5.4-128
When configuring the logic circuit, be sure to consider the processing order of the customizable logic.
Otherwise, signal delay due to slow processing of the logic calculation occurs, causing failure of obtaining
expected output, delayed operation, or output of hazard signals.
When the function code (ex. U code) relating to the customizable logic is changed, or when the
customizable logic cancel signal
CLC is turned on, the operation sequence may change in some settings,
and the operation unexpectedly and suddenly starts, causing danger. Secure sufficient safety before
executing the process.
An accident or injuries could occur.
Customizable logic timer monitor (Step selection) (U91)
To monitor the timer operation status in the customizable logic, the monitor function codes and keypad can
be used.
