2. System Reconfiguration
When connecting the MW100 for the first time, or when changing the position of an installed input/output
module on the connected MW100, reconfiguration is performed to match up the system with the actual
modules. Before reconfiguration, connect to the MW100 to be reconfigured.
Setting Module Information
(1). From the top screen, click System Settings > Module information under the Top item.
(2). If the Setting Module and Installed Module boxes are different, click the Reconstruct button to
reconfigure the system.
Note
Always turn the power to the MW100 OFF before attaching or removing input/output modules.
For either of the CAN bus module slot width settings of 1(10ch), 2(20ch), or 3(30ch) in the module
information display, actual CAN bus modules are shown as “MX118-CAN-M30” and virtual CAN bus
modules (empty slots) are shown as “MX118-CAN- - - -.“
The slot width occupied by a CAN bus module must be set according to the number of channels used (1-30
ch). However, since the actual module’s width is always 1 slot, this “virtual” slot width must be taken into
account when installing modules on the base plate.
If the slot width of a CAN bus module is set to 3 (30 ch used) and the module is installed in slot 0, slots 1
and 2 must be left empty. If another module is mistakenly installed into slot 1 or 2, all modules in slots 0
through 2 will be disabled.
