18.2.7 Modifying I/O Registers
WARNING
MODIFYING I/O REGISTERS MAY AFFECT THE OPERATION OF CONTROLLED
MACHINERY. IT IS THE RESPONSIBILITY OF THE USER TO DETERMINE THE
POTENTIAL HAZARDS INVOLVED. FAILURE TO OBSERVE THESE
PRECAUTIONS COULD RESULT IN BODILY INJURY.
The modify option is used to change the value of a register. The
register you want to modify does not need to be in the screen display
for you to modify it. Recall that if application tasks are running, the
value that you write to a register using this option may be overwritten
by one of those application tasks.
You must be familiar with how the registers on the module you are
working with are organized in order to use this option. Refer to the
documentation for the individual module for any questions on
register organization.
Follow the directions in 18.2.7.1 for modifying local I/O and in
18.2.7.2 for modifying remote I/O.
