Number of basic steps
12 steps
The number of steps of the FB embedded in a program depends on the CPU module used, the input/output definitions, and the
options setting of GX Works3. For the options setting of GX Works3, refer to the GX Works3 Operating Manual.
Processing
When i_bEN is turned on, the function holds the state in the FB and resets o_bData when the FB is called next or the second
time.
M+RCPU_MSynchronization_Delay1RST resets the device when the FB is called next.
M+RCPU_MSynchronization_Delay2RST resets the device when the FB is called second time.

M+RCPU_MSynchronization_Delay1RST
o_bData
• FB: FB call timing
* M+RCPU_MSynchronization_Delay2RST resets the device at the second FB call timing after FB is once called.
Restrictions or precautions
• Holds the output by the number of Delays after the status of the CPU module is changed from STOP to RUN.
*1 The RCPU that supports the inter-module synchronization function can be used. ( MELSEC iQ-R CPU Module User's Manual
(Startup))
