Fixed Scan Communication Setting/Inter-Module Synchronization Setting - Mitsubishi Electric R32MTCPU Programming Manual

Fixed scan communication setting/inter-module synchronization
setting
For Motion CPUs that constitute Multiple CPU advanced synchronous control, fixed scan communication function, or inter-
module synchronization function between CPUs must be enabled. If neither fixed scan communication function nor inter-
module synchronization function are set, a moderate error (error code: 30F5H) occurs after the Multiple CPU system power
supply is turned ON.
Refer to the following for details on fixed scan communication function and inter-module synchronization function.

• For Motion CPUs that constitute Multiple CPU advanced synchronous control, be sure to set "Synchronize"
for all CPUs in [System Parameter]  [Multiple CPU Setting]  "Operation Mode Setting"  "Synchronous
Startup Setting" in GX Works3. If "Do not Synchronize" is set, the startup timing of the CPUs differs, and a
moderate error (error code: 30F6H) may occur.
• For Motion CPUs that constitute Multiple CPU advanced synchronous control, when fixed scan
communication function is set to "Not Used", and inter-module synchronization function is set to "Use", be
sure to set "Synchronize" for all modules in [System Parameter]  [Synchronization Setting within the
Modules]  "Synchronization Setting within the Modules"  "Select Synchronous Target Unit between
Unit" in GX Works3. If "Do not Synchronize" is set, a moderate error (error code: 30F5H) occurs.
