(1) When MELSECNET/H communication unit is used
When connecting the MELSECNET/H network
module to the MELSECNET/10 network system,
specify the [MNET/10 mode] as a [Network Type].
(2) Communication interface setting by the Utility
The communication interface setting can be
changed on the Utility's [Communication Settings]
