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. Next initialize the scratchpad by 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, go to 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 through the relay output if powering an inductive load without using proper surge suppression. To correct this problem, you will need a firmware upgrade and adding surge suppression is recommended. If you prefer to do the upgrade (using your PC), contact technical support for more information. If you do not want to do the upgrade, call for a return authorization number.
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 our DL205 modular PLC system.
FAQ ID: 35

Question: Does the DL105 have analog I/O?
Answer: The F1-130 does not have analog I/O. If you need either 1 analog input or 1 analog output, you can use an analog to pulse generator for your input and bring it in as a high speed input on the DC input version for the F1-130. Or, you could use a pulse to analog generator for your analog output using the pulse output mode on the DC output version of the F1-130. Contact Calex at (800)542-3355 for information on their analog modules.
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. Please call technical support for information on upgrading the DL105 firmware.
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.
FAQ ID: 38

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.
FAQ ID: 39

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)
FAQ ID: 42

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

Question: Can the DL105 communicate any faster than 9600 Baud?
Answer: No.
FAQ ID: 319

Question: Does the DL105 CPU support SBR instruction??
Answer: No.
FAQ ID: 320

Question: Can you put an encoder on the DL105?
Answer: Yes, this is explained in section 3 of the D1-USER-M.
FAQ ID: 383

Question: I forgot my password, what are my options?
Answer: Once you have contacted Tech Support, someone will request that you send in your CPU to his or her attention. Always remember to save your program before sending in your unit. The program inside the CPU will be lost and irretrievable when we clear the password.
FAQ ID: 384

Question: Where can I obtain the most current firmware for my CPU?
Answer: Go to the following links on our website to check for availability of firmware. Technical Support / Firmware Upgrades / Firmware Only.
FAQ ID: 385

Question: Can a modem be used with the DL105?
Answer: No, because it only uses K-Sequence and does not have the CTX/RTX functions. The DL05 has the functions.

Answer: 1.5 amps
FAQ ID: 590

Question: Does the DL105 have UL approval?
Answer: Yes, both UL and CUL.
FAQ ID: 650

Question: Can I communicate to a single DL105 from 2 masters?
Answer: No. Only one master at a time.

FAQ ID: 783

Question: Q: On a F1-130DR-D can you run separate 24vdc+- to an input group?
Answer: A: Yes, you can, but you need to share it with supplied local common and tie it to a ground on incoming feed.
FAQ ID: 784

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.
