DL105 PLC User Manual, 3rd Edition

I/O Point Troubleshooting

If you suspect an I/O error, there are several things that could be causing the

problem.

High-Speed I/O configuration error

A blown fuse in your machine or panel (the DL105 does not have

internal I/O fuses)

A loose terminal block

The auxiliary 24 VDC supply has failed

The Input or Output Circuit has failed

When troubleshooting the DL105 Micro PLCs there are a few facts you should be

aware of. These facts may assist you in quickly correcting an I/O problem.

HSIO configuration errors are commonly mistaken for I/O point failure

during program development. If the I/O point in question is in X0--X3, or

Y0--Y2, check all parameter locations listed in Chapter 3 that apply to

the HSIO mode you have selected.

The output circuits cannot detect shorted or open output points. If you

suspect one or more faulty points, measure the voltage drop from the

common to the suspect point. Remember when using a Digital Volt

Meter, leakage current from an output device such as a triac or a

transistor must be considered. A point which is off may appear to be on

if no load is connected the point.

The I/O point status indicators are logic-side indicators. This means the

LED which indicates the on or off status reflects the status of the point

with respect to the CPU. On an output point the status indicators could

be operating normally while the actual output device (transistor, triac

etc.) could be damaged. With an input point, if the indicator LED is on

the input circuitry is probably operating properly. Verify the LED goes off

when the input signal is removed.

Leakage current can be a problem when connecting field devices to an

I/O point. False input signals can be generated when the leakage

current of an output device is great enough to turn on the connected

input device. To correct this install a resistor in parallel with the input or

output of the circuit. The value of this resistor will depend on the amount

of leakage current and the voltage applied but usually a 10K to 20K

resistor will work. Verify the wattage rating of the resistor is correct for

your application.

Because of the removable terminal blocks on the DL105, the easiest

method to determine if an I/O circuit has failed is to replace the unit if

you have a spare. However, if you suspect a field device is defective,

that device may cause the same failure in the replacement PLC as well.

As a point of caution, you may want to check devices or power supplies

connected to the failed I/O circuit before replacing the unit with a spare.
