Sampling intervals
The table opposite shows the sampling intervals for conversion
of the input signals into internal values and conversion of the
internal values into output signals (hardware conversion).
The sampling interval for software calculation of function
blocks AINP1, AINP3...AINP6, DINPUT, STATUS, CONST, LED,
INFO, OUT1...OUT5 and DIGOUT is 100 ms.
Input or output
Sampling interval
INP1
at intervals of 200 ms
INP3 / INP4
at intervals of 100 ms
INP5
at intervals of 800 ms
INP6
at intervals of 400 ms
di1...di12
at intervals of 100 ms
OUT1...OUT5 / do1...do6 at intervals of 100 ms
Calculation of the other
function blocks is at equal
intervals according to their alloca-
tion to the 8 time slots of 100 ms
each.
Allocation of a block to one or
several time slots (at intervals of
100, 200, 400 or 800 ms) is in the
engineering. For each block, the en-
gineering tool provides an identifi-
cation (ts) which can be used to
determine the allocation from the
table opposite.
The total of calculation times of all
required function blocks must be <
100 % for each time slot.
30.3
EEPROM data
Data are stored in non-volatile EEPROM. The manufacturers specify approx. 100 000 permissible write/read cycles per
EEPROM address, in reality, however, this value can mostly be exceeded by a multiple. If parameters and configura-
tions are changed exclusively manually, exceeding the max. number of write/read cycles is almost precluded. With dig-
ital interface or automatic parameter changes, however, taking the maximum number of write/read cycles into account
is indispensable, and measures against excessively frequent parameter writing must be take
