Function
Via the connection actively established by the SIMATIC S5, data are sent
bidirectionally with a count value to the S7-1500 every second. From there, this
count value is mirrored and sent back. After the data have been received, this
count value is increased by +1 and sent again.
In case of the SIMATIC S5 CPU being restarted, a deletion identifier is sent to the
S7-1500 and the count value is reset.
