Section 6 PROFINET Telegram composition
The format of the PROFINET tags can be integer (2 bytes), unsigned integer (2 bytes) or float
(4 bytes).
The data transmission between the SC4500 controller and the PLC can have a maximum of 7 slots,
where each slot has a quantity of bytes used in the Telegram.
The size of data sent from the SC4500 controller to PLC is calculated with the input modules. The
size of data sent from PLC to SC4500 is calculated with the output modules.
The algorithm in the PROFINET module uses the rules that follow:
• The minimal number of slots are used.
• The byte modules are used from higher to lower without repetition. The modules available are
128 bytes, 64 bytes, 32 bytes, 16 bytes, 8 bytes, 4 bytes and 2 bytes.
• Because the module cannot be higher than 128 bytes and it cannot be repeated, there is one
module of 128 bytes for each slot.
• The maximum capacity of the Telegram is 768 bytes for input data and 128 bytes for output data.
