About Anybus Communicator
Frame fields are low level entities used to compose transactions.
A frame field can represent a:
fixed value, a constant
range of values, limit objects
block of data or a calculated checksum
Transaction Templates
The Transaction templates are available when either the Custom Request/Response or Custom
Produce/Consume serial protocol is enabled.
A transaction represents a complete serial telegram, and consists of a number of frame fields.
Each frame field is associated with a set of parameters controlling what is transmitted on the
subnetwork.
The transaction templates are stored in the Communicator and can be reused multiple times.
