6.4 Communication Function via PERIPHERAL I/F
The Motion CPU can communicate data by connecting built-in PERIPHERAL I/F of the Motion CPU with personal computers
and/or display devices, etc. using an Ethernet cable. There are following two ways to communicate between the Motion CPU
and MT Developer2.
• "Direct connection" connected with the Ethernet cable
• "Connection via HUB" connected via HUB
The Motion CPU does not support SLMP. PERIPHERAL I/F cannot be used for SLMP communication.
Direct connection
Between the Motion CPU and MT Developer2 can be connected using one Ethernet cable without HUB. The direct
connection enables communication with only specifying connection target. IP address setting is not required.
If connecting directly with an Ethernet cable, the wiring will be longer than a USB cable, and therefore it is
possible that an unauthorized connection may be established from a distance.
By setting [R Series Common Parameters] [Motion CPU Module] [Module Parameters] "Disable Direct
Connection to MELSOFT" to "Disable" in order to prohibit a direct connection to MELSOFT, direct connections
are prohibited, enabling unauthorized connections to be prevented.
