Analog & Digital Input/Output Issues

Problem: The screen doesn’t reflect changes made in the analog inputs.

Solution:

1. Verify that the position of Dip Switch (S1-S6) corresponds with the relevant analog input.

2. Verify that the analog input terminals’ mapping corresponds to the actual wiring.

3. Check that the terminal wire connection of Analog Input of interest coincides with the analog input chosen on the touch screen.

Problem: The screen doesn’t reflect the changes in digital inputs.

Solution: Verify that the digital input terminals’ mapping corresponds to the actual wiring.

Problem: The end user doesn’t see changes in the data tables.

Solution:

1. Check the Internet cable, going from RJ-45 connector (marked as Ethernet-2). Verify that the connector’s LEDs are flashing.

2. Check the Internet cable, going from the power card to the Trio display’s card RJ-45 connector (marked as Ethernet-1). Verify that the connector’s LEDs are flashing.

Problem: The analog output voltage doesn’t correspond to the voltage defined on the corresponding analog output terminal.

Solution: Check the load value. The maximum analog output load is 15 mA.

Problem: An analog output terminal has no output voltage.

Solution: Verify that the analog output terminals’ mapping corresponds to the actual wiring.
