UIO-4033 & UIO-4035 both have eight DI ports and eight DO ports.
Show DI/DO Ports
List DI/DO supported ports:
Show DI/DO Ports
# #---- Show DI ports ----# # # cd /dev/ # ls DI* DI1 DI2 DI3 DI4 DI5 DI6 DI7 DI8 # #---- Show DO ports ----# # # cd /dev/ # ls DO* DO1 DO2 DO3 DO4 DO5 DO6 DO7 DO8
Get DI Status
Take DI1 for example
# cat /dev/DI1 1
Note:
1. DI ports have two types: Dry or Wet.
2. For Dry ports
0 means the external circuit is conductive.
1 means the external circuit is NOT conductive.
3. For Wet ports
0 means the voltage of input is between 10-30V
1 means the voltage of input is between 0-3V
3-10V is unstable status.
Set and Get DO Status
Take DO1 for example:（The DO interface of UIO-4033 is of sink type）
# #---- Set 0 to DO1 ----# # # echo 0 > /dev/DO1 # #---- Set 1 to DO1 ----# # # echo 1 > /dev/DO1 # #---- Get DO1 status ----# # # cat /dev/DO1 1
The wiring and measurement methods can be referred to as shown in the following diagram.
