Communication Destination Setting
The settings differ depending on the communication destination.
Specify the protocol and own station port number for each setting to be the same as those set in the simple CPU
communication settings.
*1 Since the MELSOFT connection is used for communications, no setting is required.
*2 The module has the setting by default to communicate with one device whose protocol is "UDP".
*3 Up to 64 devices can be connected to each port of the CPU module (built-in Ethernet port part) or the Ethernet module.
*4 Up to nine devices can be connected.
Target PLC No.
When the communication destination is set to "Mitsubishi iQ-R (Built-in Ethernet)" or "Mitsubishi Q (Built-in Ethernet)" and a
multiple CPU system is configured, set the "Target PLC No." of the communication destination.
Number of device points
The maximum number of points per setting is 1024 words (bit device 8192 points maximum, word device 512 points
maximum).
Set the devices within the device range specified with the parameter of the CPU module.
