Control I/O Function Control I/O Function
Control I/O Function
The control I/O is the interface to communicate system status and sequence
commands between the indicator and peripherals.
Input terminals ...................11 lines that can be selected by the function
Output terminals ................11 lines that can be selected by the function
The output terminals use open collector transistors
Preset the functions to these terminals. Refer to "11. Function List".
[Function] - [Set function] - [Control I/O]
Caution
Do not assign the same function to multiple terminals of the control I/O and OP-05.
