Intelligent Modules Con figuration Data Format

Configuration files of intelligent modules may exceed the 128-byte maximum length of a Genius

message. Therefore, any Write Configuration to an intelligent module must be contained within a

Begin/End Packet Sequ en ce. The BIU rejects any Writ e C onfi guration message for an int elligent

module that does not follow a Begin Packet message.

Write Configuration for an intelligent module may be packetized by using the upper nibble of the

slot byte to indicate a packet number. Data for packets greater than zero is assumed to have an

offset with a slot configuration of (packet_number*128). Therefore, all packets except the last must

have 128 bytes.

Note that all reserved or unused bits must be 0.

Configuration Data for Intelligent Modules, B ytes 0 to 13

The first 13 bytes of configuration data for intelligent modules have the content shown below. Each

intelligent module has additional configuration data listed on the following pages.
