T.8 Errors displayed with an expansion unit

See the following sections for the description and handling method of the error code.

Can the device connected to the FLEX NETWORK board perform input and output functions normally?
Check whether the device connected to the FLEX NETWORK board performs input/output operations properly in order to determine whether the problem is in the GP or not.

When DIO (Example: FN-X16TS) is used

1. Go to offline mode and touch [Peripheral Settings] on the item changeover switch.

2. [Peripheral Settings] screen opens. Touch [I/O Driver] and then [FLEX NETWORK Driver].

3. [I/O Driver] screen opens. Touch [I/O Monitor].

4. [I/O Monitor] screen opens. Set the [Transmission Speed], [S-No.], [Model], and [Type]. (Example, S-No.= 1, Model= Input FN-X16TS, Transmission Speed= 6Mbps, Type=Bit)
   

5. The bit monitor screen is displayed, showing the ON/OFF status. A protruding switch indicates OFF and a depressed switch indicates ON.
   

6. When the connection device is operating normally

When the connection device is operating normally, check the following GP-Pro EX settings because there is no problem with the Display side and the unit side:

1. Verify whether or not the correct unit is selected in [Unit (U)] in [I/O Driver Setting] in the [System Settings].

   M.19.1 [Home] Setting Guide

3. Verify whether or not [Logic Programs] in [System Settings] is set to [Enable] in offline mode or with GP-Pro EX.

4. When the connection device is not operating normally

When the connection device is not operating normally, check the wiring of the Display and connected device and then the following items:

Check if the cable is functioning normally by performing a communication check.

Check whether the FLEX NETWORK unit connected to the FLEX NETWORK board can communicate properly.

1. Go to offline mode and touch [Peripheral Settings] on the item changeover switch.

2. [Peripheral Settings] screen opens. Touch [I/O Driver] and then [FLEX NETWORK Driver].

3. [I/O Driver] screen opens. Touch [Check Comm].

4. [Start]. Touch the button.
   

5. The communication check screen will display. When no problem is found with the communication, the total number of units that communicated successfully and the S-No assigned to the units are highlighted. If communication is successful, please check whether the device connected to the FLEX NETWORK unit operates properly or the cable is correct.
   
   If communication fails, check the communication cable for breaks, the power supply of the unit, and the termination resistor of the unit. If the problem continues, the I/O unit or display unit may be faulty. Please contact the Pro-face customer care center.
