Program sequence or test routine execution/documentation device, has variable that maintains specific value, when value of variable is equal to certain value and external control signal having initial signal level is re-applied

摘要

The device has a control input which received the external control signal. The device (1) has a variable (10) which can be altered depending on the external control signal, and assumes a specific value which is different from a certain value, when an external control signal has an initial signal level. The variable maintains the specific value, when the value of the variable is equal to the certain value and an external control signal having a first signal level is re-applied.
