7.6.3 Frame Field Types
Each transaction consists of frame fields which makes up the serial telegram frame.
Each frame field specifies how the Communicator shall interpret or generate a particular part of
the telegram.
The following frame fields are available:
Node address
Frame field representing the Node address of the Node.
A constant byte that holds a copy of the nodes address when the transaction is used by a node.
Constant
Constant frame fields are handled differently depending on the direction of the transaction:
Produce/Request Transactions
The Communicator sends the value as it is without processing it.
Consume/Response Transactions The Communicator checks if the received byte/word/dword matches the specified
value. If the message does not fit, it is discarded.
Limit
Limit is not available for the Transaction Type Produce.
Consume/Response Transactions The Communicator checks if the received byte/word/dword fits inside the specified
boundaries. If the message does not fit, it is discarded.
Data
Data frame fields are used to represent raw data as follows:
Produce/Request Transactions
The specified data block is forwarded from the higher level network to the sub-
network.
Consume/Response Transactions
The specified data block is forwarded from the sub-network to the high level
network.
Variable data
Produce/Request Transactions:
The specified data block will be forwarded from the higher level network to the sub-network.
The control system must supply an End or Length character in order for the Communicator to know the size of the data
block.
The End- or Length-character itself may either be forwarded to the sub-network or discarded.
Consume/Response Transactions:
The specified data block is forwarded from the sub-network to the higher level network.
The End- or Length-character will be generated by the Communicator automatically (if applicable).
The End- or Length-character itself may either be forwarded to the higher level network or discarded.
