Caution
• Immediately after power up, the digital I/O data of standard slaves and expansion slaves cannot
be accessed. Data communication between the CPU module and the connected slaves starts when
special internal relay M1945 (Normal_Operation_Active) turns on. Make sure that M1945 is on
before starting to access the slave I/O data.
