13.7 Additional DIO Modules
Setting the Module Address
Additional DIO modules can be installed in an Adept MV controller, up to a maximum of
8 modules per controller, depending on slot availability. The total digital I/O channels
available, including the channels on the SIO modules are:
• maximum digital input channels = 268
• maximum digital output channels = 264
Each module that is added must have a unique VMEbus address so the controller can
recognize it properly. The address is set at DIP switch S1 on the DIO PC board. The switch
settings are shown below. See Figure 13-3 for the location of S1.
Labeling Sets of Cables
The optional Adept input and output cables for the DIO modules are the same for each
additional module you that add to a controller. Make sure to clearly label each set of four
cables so that they are identified with a specific DIO module. Also see the warning on
page 148 about swapping the two input cables or the two output cables with each other.
