1 OVERVIEW
(9) Easy settings using the utility package
A utility package is sold separately (GX Configurator-DA).
The utility package is not a required item, however, it is useful for on-screen
setting of the intelligent function module parameters (initial setting/auto refresh
setting). In addition, FB
1
can be generated automatically from the intelligent
function module parameters that have been set up and used in a sequence
program.
1 FB is the function for making a circuit block used in a sequence program
repeatedly a part (FB) to use it in the sequence program.
This function can improve the efficiency of program development and
minimize program bugs to improve program qualities.
For the details of FB, refer to "GX Developer Version 8 Operating Manual
(Function Block)."

Chapter 7
Using the mode switching setting (buffer memory addresses 158, 159:
Un\G158, Un\G159) and operation condition setting request (Y9), the
module is switched between the normal mode and offset/gain setting
mode without the PLC CPU being reset.
Section 3.4.12
Using the dedicated instruction (G.OFFGAN), the module is switched
between the normal mode and offset/gain setting mode without the
PLC CPU being reset.
Appendix 3.1
Mode switching that does
not require PLC CPU to be
reset
Using GX Configurator-DA, the module is switched between the normal
mode and offset/gain setting mode without the PLC CPU being reset.
