Intelligent Modules Configuration 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 Sequence. The BIU rejects any Write Configuration message for an intelligent
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, Bytes 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.
