4.10.4 Time Range
Variable values as time setpoint (analog inputs I7, I8, I11, I12, actual value T1
to T16, C1 to C16).
4.10.4.1 Variable time setpoints
When using variable values, such as the actual value of a different timing
relay, easy will only accept its output value with the conversion. The time
range selected for this timing relay is ignored.
The following conversion rules apply:
For "s" time base
With the time base “s” the value is accepted as a “value in ms”. The last
position is rounded up to a zero or five.
Equation: Time setpoint = ( Value x 10) in [ms]
Parameters Time range and setpoint time Resolution
S 00.000
Seconds: 0.00 to 99,990 s 10 ms
M:S 00:00
Minutes: Seconds 00:00 to 99:59 1 s
H:M 00:00
Hours: Minutes, 00:00 to 99:59 1 min.
￫
Minimum time setting:
If a time value is less than the logic relay's cycle time, the
elapsed time will not be recognized until the next cycle. This
may cause unforeseeable switching states.
￫
If the value of the variable is greater than the maximum
permissible value of the configured time range, the maximum
value of the time range will be used as the setpoint.
￫
If you are using analog values as time setpoints, ensure that the
value of the analog input is stable. Oscillating analog values
deteriorate the reproducibility of the time value.
Value, e.g. Analog input Time setpoint in [s]
0 00.00
100 01.00
300 03.00
500 05.00
