Testing of the intelligent function module

•
When testing the operation (changing a current buffer memory value) of the intelligent module monitor, read this
manual carefully to fully understand the operation.
For devices that perform significant operations for the system, never perform test operation to change data.
Doing so can cause accidents due to false outputs or malfunctions.
Testing can be performed for all buffer memory data displayed on the current monitor screen.
This section describes the operations for changing the current value of the buffer memory and turning on and off the output
signal from the PLC CPU to the intelligent function module.
