READ_SETUP
The Profibus Master sets this bit to a 1 to instruct the I/O
Module to read the current configuration settings from the
attached LaserSpeed gauge.
WRITE_SETUP
The Profibus Master sets this bit to 1 to instruct the I/O
Module to transmit the configuration settings transmitted in
the Profibus Data Exchange message to the attached
LaserSpeed gauge.
READ_STATUS
The I/O Module sets this bit in its output Profibus message
in response to the Profibus master setting the
READ_SETUP bit. When this bit is set to 1, the I/O Module
has completed reading the configuration settings from the
LaserSpeed gauge, and has copied them into the Data
Exchange message. When this bit is 1, the settings in the
Data Exchange message contain valid data.
WRITE_STATUS
The I/O Module sets this bit to 1 in its output Profibus
message to acknowledge that is has received the
WRITE_SETUP command. The I/O module clears this bit to
0 after the configuration settings have been transmitted to
the LaserSpeed gauge and verified.
