pre-installed model module
When changing the IP address using this function, CCPU parameters managed by the Setting/monitoring tools for the C

Therefore, when changing the IP address with this function and reading it from the module using the Setting/monitoring tools
for the C Controller module, the IP address that is changed by this function is read.
■When changing the IP address of a MELSEC iQ-R series SECS/GEM communication software
pre-installed model module
When changing the IP address of MELSEC iQ-R series SECS/GEM communication software pre-installed model module by
using this function, the module operates with the IP address set in GX Works3 from when the power is turned ON to when
