Appendix B: DIO Type Define of I-8050 Modules
I-8050 is a selectable 16-channel DIO module. User can decide which channel
will be DI and which channel will be DO. In CAN-8x23, users can achieve this purpose
by setting the type code in the object index 0x2004~0x2007. The object index 0x2004,
0x2005, 0x2006 and 0x2007 are for the module plugged in slot 0, slot 1, slot 2 and slot
3 respectively.
For example, if the I-8050 module is plugged on the slot 0 of CAN-8423, user can
set the object index 0x2004 to decide the channel type of I-8050. The object index
0x2004 with sub-index 1 controls the channel type of ch-0 to ch-7 of I-8050, and
sub-index 2 controls the ch-8 to ch-15. If one bit of the object data is set to 1, it means
that the corresponding channel will be set to DI. So if users set the sub-index 1 to
0x77, it means that only the ch-3 and ch-7 are DO channels and the others are DI
channels. In default, all the channels of I-8050 are DI channels.
