Operating principle (reading):
w Enter the index number into ‘Index OUT’ (Read).
w After the index number is mirror-inverted in ‘Index IN’ (Read), the read value is stored in
‘Read Value’ .
Operating principle (writing):
w Enter the index number into ‘Index OUT’ (Write)
w Enter the value to be written into ‘Write Value’.
w After the index number is mirror-inverted in ‘Index IN’ (Write), the value was transmitted.
g
To ensure consistent data transmission, ‘Index OUT’ (Write) and ‘Write Value’ must have been updated
safely before a PROFIBUS data cycle. If this cannot be ensured, proceed as follows: ‘0’ in ‘Index OUT’
(Write), write the value to be transmitted into ‘Write Value’ and write the index number into ‘Index OUT’
(Write). With entry ‘0’ in ‘Index OUT’ (Read) / ‘Index OUT’ (Write), no data are transmitted.
