Timer variable settings using PLC drivers
The user can set variable timers of user’s PLC logics using settings of PLC drivers (FB:
PLC_DRV 230302). The LCD screen menu provides settings [
UTM1
] ~ [
UTM24
], and the user
can set those timer values through the LCD screen.
Figure 7.4-1 shows that a delay timer “TON1” has been set 500ms in the PLC logic, but the
user can set new value using the setting [
UTM1
] (e.g., the user can change 500ms to 200ms on
the LCD). Since an internal IED memory is able to access the [
UTM1
], the IED can operate
with new value of the [
UTM1
] when new one is set.
