FEC AFC1500 - Manual (Page 50)

ANYBUS-S Reference
AnyBus S Initialization
FEC incorporates the ANYBUS module as the interface to various fieldbus
communication devices. (manufactured by HMS, www.hms.se) It is intialized
by the AFC 1500 Multi Unit which sets certain parameters including the size
of the Input / Output tables to be used for the particular fieldbus. All
fieldbus’s except for the Allen Bradley Remote I/O use the “-S” type of
AnyBus Card. This provides interchangeability between the cards while
minimizing software changes. This also allows FEC to set parameters to all
the different types of fieldbus cards with the same parameter set-up software.
The AFC User Console has the function included to set the parameters, mainly
Input / Output size, to the Anybus card. Below is an example of the
command structure. The “Message Data” area near the bottom is where the
I/O size is set.
NOTE: FEC sets this at the Factory, and does not recommend setting this
by the end user. This information is provided for reference only.

In the AFC User console Multi-fieldbus setup, the (S Type) setup menu is
used to input/download this data. Other commands are required to transfer
this data, but the command “000A” is the command which sets the I/O size.
