Question:
How do I reset my processor back to factory defaults?
Answer
Resetting the processor to factory defaults is a two step process. First clear the processor memory by:
- PLC >> CLEAR PLC MEMORY
- PLC >> SETUP >> INITIALIZE SCRATCHPAD
Be aware that initializing the scratchpad will reset the system V-memory to defaults. System V-memory contains parameters such as retentive ranges, DV-1000 setup parameters, etc.

Question:
My inputs X0-X3 and/or my outputs Y0-Y1 are not working. What's wrong?
Answer
The PLC is most likely in a high speed counter mode. When in high speed counter mode inputs X0-X3 and/or Y0-Y1 will not act as normal I/O. To reset the processor to treat X0-X3 and Y0-Y1 as normal I/O, Initialize the scratchpad by:
- PLC >> SETUP >> INITIALIZE SCRATCHPAD

Question:
How can I override inputs and outputs in my DL105?
Answer
The F1-130 does not support override. You can turn bits on or off with Data View for a single scan to trigger events, but the PLC will update the image register on the next scan. The inputs will reflect their actual state and the outputs will be the result of the rung that controls them.
You can control outputs by loading a program that consists of an END statement only. From DEBUG>DATA VIEW>NEW/OPEN you can then select the particular bit and use the on/off button to control the element. You can not control inputs.

Question:
The run indicator on the CPU is flashing. What's wrong?
Answer
The CPU has gone into update mode. This can be caused by an electrical spike to the incoming power or by the relay outputs, if powering an inductive load without using proper surge suppression.
To correct this problem, you will need update the firmware. You will need the Koyo Support Tool and DL105 Firmware file
If your issue was relay output related, please see AN-MISC-032 for correcting relay transient issue.
FAQ ID: 33
Question:
Can the DL105 be networked?
Answer
No, the F1-130 is a stand alone unit. It has one RS232 communication port that can be used for programming or operator interface panels that communicate using K-Sequence protocol at 9600 baud.
FAQ ID: 34
Question:
Can additional I/O be added to the DL105?
Answer
No, the F1-130 is fixed I/O with 10 inputs and 8 outputs. If you require more I/O points, check out DL05/06, Click, BRX, or Productivity PLC platforms. Programmable Controllers
FAQ ID: 35
Question:
Does the DL105 have analog I/O?
Answer
The F1-130 does not have analog I/O.
If you need a small brick PLC with analog capabilities, please see DL05/06, Click, and BRX platforms. Programmable Controllers
FAQ ID: 36
Question:
Why can't my DL105 represent negative counts when I use Mode 20 of the High Speed Counter feature?
Answer
This feature was added in version V1.11 of the firmware in July 1998.
You will need to update the DL105 firmware for that functionality. To update the firmware, you will need the Koyo Support Tool and DL105 Firmware file
FAQ ID: 37
Question:
My DL105 drops out of run mode intermittently. What's wrong?
Answer
This problem occurs only with the relay output version of the DL105. If the relay is driving an inductive load, the load needs to be suppressed using any MOV or TVS. This prevents EMF (noise) from traveling back to the relay and will keep the DL105 from dropping out of run mode.
Please see AN-MISC-032 for information on correcting relay transient issue.

Question:
How long will the DL105 retain its memory while powered down?
Answer
The ladder logic is written to EEPROM, which is non-volatile. The V-memory is backed by a super capacitor that will last approximately one week.

Question:
What is the torque specification on the DL105 terminal block screws?
Answer
6 inch-ounces.
FAQ ID: 40
Question:
What is the accuracy of the PLC real-time clock?
Answer
The DL105 has no clock/calendar feature
FAQ ID: 41
Question:
What is the accuracy of the timer instructions?
Answer
The accuracy of the timer instruction is the same as the accuracy of the clock generator used for the microprocessor in the DL105. The accuracy of the clock generator is +/- 50 PPM. So the accuracy of the timer instruction is: +/-50 PPM * 60 sec * 60 min * 24 hr = +/- 4.32 seconds (per day)

Question:
Are there any plans to CE List or Recognize the DL105?
Answer
At this time, there are no plans to CE List this product line.
FAQ ID: 43
Question:
Does the DL105 support DNP 3.0 protocol?
Answer
At this time, it does not.
FAQ ID: 44
Question:
How would we check this PLC to make sure that it is calibrated?
Answer
Our PLCs do not require calibration.
FAQ ID: 45
Question:
Can you network a DL105 and a D3-340?
Answer
No...the DL105 supports only K sequence and the D3-340 supports DirectNET. We suggest using a DL05 instead of a DL105 in this case.
FAQ ID: 46
Question:
Is there a force option in the DL105?
Answer
Not at this time.
FAQ ID: 48

FAQ ID: 320
Question:
Can you put an encoder on the DL105?
Answer

FAQ ID: 383
Question:
I forgot my password, what are my options?
Answer
If the password is lost or forgotten, you will have to return the PLC to AutomationDirect, to get the password cleared. The CPU contents will be erased when we clear the password, there is not a way to retrieve the project.
Contact Tech Support to get a Equipment Evaluation form to fill out and return with your PLC. Once AutomationDirect has the signed form and PLC, we can clear the PLC and return it back to you.
AutomationDirect can only perform the password clear if the PLC is being shipped back to a United States address, we cannot ship the PLC outside of the US.

FAQ ID: 385
Question:
Can a modem be used with the DL105?

Question:
What is the SCCR rating for the DL105 PLCs?
Answer
Our PLCs are not power circuit components. The SCCR is not required for them. Please refer to UL508 177.1 and UL508A SB4.1 for details.
UL508 177.1 defines what the PLC is and UL508A SB4.1 covers the standard for the SCCR.

Question:
How do I use a variable as a timer preset?
Answer
In your timer box where you are currently typing 'Kxxx' for the preset you would put a V memory address such as V2000. Make sure that this address is only used for this purpose. Now open a data view and type in V2000. You would use this same V memory address for every timer that you want to have the same value.
Click the yellow E button with the red circle and slash in the upper left of the data view window to enable edits. Now you should have a column titled edits on the right of the V2000 you typed in. Enter your value in this column next to V2000 and press the middle of the three buttons at the top right of the data view.
Please note that you can use other V memory addresses than V2000. The full list of available addresses is available in the PLC -> Memory map menu item. Also you can find the list of available memory in Chapter 3 (or 4 depending on the PLC model) of the User manual.
