5.9 Module Reset Function from Sequence Program
This function resets a module from a sequence program without resetting the PLC or the
master block when the switch settings are changed or an error occurs in the master block.
However, reset is disabled when there is an read module error (when the BFM#A
H
b0 is
ON).
The figure below shows a program example for module reset.
Point
Because the PLC is not initialized, operations of other modules are not affected at
all.
Remarks
Change from the mode 0 or the mode 2 to the test mode cannot be executed by the
write request for module reset (BFM#A
H
b4).
For such a change, turn off the power, then turn it on again.
