T.5.1 Devices connected to the
DIO interface do not turn ON/OFF
Do the devices connected to the DIO unit
produce input/output properly?
Check whether the device connected to the DIO board performs
input/output operations properly in order to determine whether the
problem is in the display unit or not.
-
Go to offline mode and touch [Peripheral Settings] on the item
changeover switch.
-

ON and OFF. If the device connected to the DIO board performs
properly. Please check the settings of the project file on GP-Pro
EX. If the connected device does not operate normally, check the
wiring between the display unit and the connected device, and then
check the following items.
Do the internal terminals of the GP operate
properly?
You need to prepare a loopback cable to check the internal
terminals.
Prepare the loopback cable according to the following
instructions.
Preparing
the loopback cable
The wiring of the loopback cable is as follows:
Example, to check three terminals at a time,
IN0 through IN2 on OUT0, and IN3 through IN5 on OUT1
Example, to check three terminals at a time,
IN0 through IN2 on OUT0, and IN3 through IN5 on OUT1
I/O
Check
Connect the loopback cable to
the DIO board, send data from the two output terminals to the six
input terminals, and compare the input and output data. When the
data matches with the expected value, [OK] is displayed on the screen.
When the data does not match with the expected value, [NG] is displayed.
-
Go to offline mode and touch [Peripheral Settings] on the item
