Appendix C
System Setup, Auxiliary Area Allocations,
and Built-in I/O Allocations
Overview of System Setups
A System Setup contains software settings that the user can change to customize FQM1 operation. Module
functions are set using its System Setup.
The Coordinator Module and Motion Control Modules all have System Setups, which are set from the CX-Pro-
grammer to customize operation for the following types of applications.
The addresses given for the settings in the System Setup are not required for actually making the settings. Use
the menus of the CX-Programmer Ver. 5.0@.
System Setup in the Coordinator Module
Sync Settings between Modules (CX-Programmer: Module Settings Tab Page)
Allow Writing to User Memory
Prohibit System Interrupt of the Sync Mode
Cases when settings must be changed Setting(s) to be changed
• When programming the FQM1 for the first time and the Motion Control
Modules are being programmed before the Coordinator Module.
• When editing or debugging the program in a specific Motion Control Mod-
ule.
Sync Mode
• When you want the FQM1 to go into RUN mode or MONITOR mode and
start operating immediately after startup.
• When you want the operating mode to be other than RUN mode when the
power is turned ON.
Startup Mode
When the peripheral port will not be used with the CX-Programmer (periph-
eral bus) communications speed auto-detection and will not be used with the
default Host Link communications settings, such as 9,600 bps.
Peripheral Port Settings
When the RS-232C port will not be used with the CX-Programmer (periph-
eral bus) communications speed auto-detection and will not be used with the
default Host Link communications settings, such as 9,600 bps.
Host Link Port Settings
When you want to communicate with a PT via an NT Link. Peripheral Port Settings or Host Link Port Settings
You want a constant (minimum) cycle time setting to create a consistent I/O
refresh cycle or cycle time.
Cycle Time
You want to set a maximum cycle time other than 50 ms (1 ms to 100 ms). Watch Cycle Time
You want to extend peripheral servicing time because peripheral services
are being executed over several cycles, delaying completion of servicing
(want to set a specific time rather than a percent of the cycle time).
