Cyclic Send

Description
The "Cyclic Send" function blocks allow you to specify the information to be
transferred cyclically to the automation system via PROFIBUS DP .
"Cyclic Send" function blocks consist of:
• Eight bits each (two bytes, byte 0 and byte 1 for binary information)
• Four words (= eight bytes, byte 2 to 9 for four analog values, freely
parameterizable)
• One output to PROFIBUS DP each.
Overall there are three "Cyclic Send" function blocks (0, 1, 2/9).
