| FAQ ID: 1018 |
| Question: Do you have an adapter for the D2-DSCBL and EZ-2CBL cables so that I can use them on port 2 of a DL06, DL250-1, or DL260 instead of on port 1? I’m using DirectSoft32 with the RJ-12 PLC connector cable (D2-DSCBL) and/or I’m using an EZ-Text/EZ-Touch panel with the RJ-12 PLC connector (EZ-2CBL) to connect to port 1 of my DL06, DL250-1, or DL260 PLC. I want to connect to port 2 of these processors, which has a 15-pin high density connector. |
| Answer: Yes, in any of the situations listed above, you can use the FA-15HD adapter to connect to port 2 of a DL06, DL250-1, or DL260. The FA-15HD adapter will work with DirectSoft32 and the D2-DSCBL, or with an EZ-Text or EZ-Touch panel and the EZ-2CBL cable to allow them to connect to port 2 of the DL06, DL250-1, or DL260. Since port 2 is configurable on these PLCs, you must make sure the protocol and port settings match on both devices. The FA-15HD adapter can be used with the D2-DSCBL, the EZ-2CBL, or the FA-CABKIT. The FA-15HD adapter can NOT be used with the DV-1000 or the D2-HPP. |

Click here for Chapter 2 of Options Manual. c. You can also get information under PLC/Configure IO. Look in the slot under the Address In and Address Out column for starting address. d. Combo modules require more information found in Options manual. D0-OPTIONS-M. Click here for Options Manual. |
| FAQ ID: 1172 |
| Question: Output LED comes on but nothing happens in the field, what could be the problem? |
| Answer: a. Discrete outputs on a D0-06DD1 model, needs to have V+ terminal connected to 24vdc or positive voltage of DC power source. b. Discrete outputs on a D0-06DD2 model, needs to have C0 terminal connected to 0vdc of DC power source. |
| FAQ ID: 1173 |
| Question: I added analog IO pointer method during online edits. I then wrote to changes to PLC. But my analog IO still does not work, where do I start checking? |
| Answer: a. Make sure you go to Program Mode, then back to RUN. If you do online edits while in RUN mode, the program mode you get when you WRITE program to PLC is just a Pause mode. You can verify by viewing values in system words (V700, V701, etc) to see if they hold the expected values. If they do not, they will populate with correct values when you power down and then power up or when you go to Program mode and then back to RUN mode. b. Information on Pointer Method is found in the D0-OPTIONS-M manual for each analog module. Click here for Options Manual. |
| FAQ ID: 1174 |
| Question: Can I configure a DL06 to do high speed counting and generate high speed pulse output? |
| Answer: a. You can do High Speed Inputs or High Speed outputs, but not both. b. Mode 10 allows you to configure two high speed counters, up to 7 KHz. c. Mode 20 allows you to configure a quadrature counter, which allows counting in clockwise and counter clockwise directions (or count up or down), up to 7 KHz. d. Mode 30 allows you to do high speed pulse outputs up to 10 KHz. It supports three profiles: trapezoidal, registration and velocity. e. Click here for Appendix E of DL06 User Manual. |
| FAQ ID: 1175 |
| Question: I need to add more IO to my DL06, what are my options? |
| Answer: a. You can use available option modules, such as: discrete IO and/or analog IO, in the four available expansion slots. b. If these are used up, it is possible to use the PLC as master to a second or multiple slave PLCs. You can use a serial or Ethernet connection and use RX/WX instructions to control the IO of other linked PLCs. This is not the preferred method to add IO. c. The end of Chapter 4 in the DL06 user manual covers networking using Modbus RTU or DirecNet protocols. Port 2 on a DL06 supports RS-232, RS-422 and RS-485. Directnet can be used with RS-232 and RS-422. Modbus RTU can be used with the same electrical connections plus it also supports RS-485. d. You should consider using a DL250-1 or DL260 CPU and the engineered local expansion and/or remote IO connections available to that family. Changing the ladder to that family can be as simple as changing the PLC type in the OFFLINE Setup. |
| FAQ ID: 1176 |
| Question: Can I read/write data from/to one or more DL PLC? How about to a non DL device? |
| Answer: a. The DL06 can use port 2 as a master using Direct Net or Modbus RTU. b. Port 2 supports RS232, and RS422, for both DirectNet and Modbus. RS485 (2-wire)can only be used with Modbus. If you use RS422 or RS485 you can communicate with a network of devices. All devices on the network need to support the protocol the master DL06 port 2 is configured for. c. If connecting to third party devices, you will use the Modbus RTU protocol. When doing so you will need to convert Modbus addressing to DL octal addressing. To help with this task, we have a Modbus Conversion utility available on our technical support page. d. Click here to download Modbus Conversion sheet. e. The DL06 supports two instructions, MRX and MWX, which allow you to address the Modbus addresses directly without the need to convert to octal addressing. f. Chapter 4 of the D0-06USER-M manual covers the communications port and networking starting on page 7. Click here for Chapter 4 of DL06 User Manual. |
| FAQ ID: 1177 |
| Question: Is it true you need to add some form of protection when using relay outputs to turn on solenoids or motor contactors? |
| Answer: a. Yes, it is true. Devices with coils, inductive loads, driven by a PLC relay output will generate a voltage spike when it is turned off. b. You should install some form of surge suppression, such as TVS, MOV or Diode, at the coil or as close to the coil of the solenoid (or other device) as possible. c. This is covered in Chapter 2 starting on page 21 of the DL06 user manual. Click here for Chapter 2 of DL06 User Manual. |

| Question: I just installed a new module in one of the expansion slots but I cannot see it in Configure I/O, what could cause this? |
| Answer: a. This is most likely the PLC firmware version. You will need to update it. b. Click here for Koyo Support Tool download.. c. Click here for DL06 firmware download. d. Install the Koyo Firmware Update Tool and follow the wizard to update the firmware in your PLC. e. Once updated, check Configure I/O. The module should now be recognized by PLC. |
| FAQ ID: 1179 |
| Question: Which formula do I use to scale an analog input if my engineering unit does not start at 0? |
| Answer: Click here for scaling formula. a. When using BCD or Binary data types, you will lose resolution since you cannot use the fractional values. You can multiply the engineering min and max values by a factor of 10 or 100 to accommodate for this to a certain extent. For example, if your engineering range is 0 to 100, use 0 to 10000. b. If you are dealing with negative values in DirectLogic PLCs, it will be easier if you use floating point data type. c. Ladder example using IBOX to scale -10 deg C to 60 deg C, where V2000 is the raw count (0 to 4095): Click here for scaling example using IBOXs. |

| Question: How do I get the absolute value of a 2s complement negative number so that I can use it as a REAL value? |
| Answer: a. It is not possible to convert a 2s complement negative number directly to a REAL value. b. Example 1 below uses V2000 as the 2s complement data source and V3000 as our converted REAL value destination. i. When a 2s complement value is negative, the most significant bit of the word will be turned on. Therefore, we check to see if V2000 is greater than hex 8000. ii. If the value in V2000 is less than hex 8000, the value is positive and we can convert using BTOR directly. (Rung 1) iii. If the value in V2000 is negative, we invert the bit pattern, add 1 to it and store 16 bit result in V3002. We then convert the positive value in V3002 to REAL, multiply it by -1 and store the result in V3000. Click here for 2s complement ladder Example 1. c. Example 2 below uses V2000 as the 2s complement data source and V2500 as our converted REAL value destination. i. When a 2s complement value is negative, the most significant bit of the word will be turned on. In this example we use the actual most significant bit (B2000.15) to determine if value in V2000 is positive or negative. ii. If the value in V2000 is positive, we convert to REAL using BTOR directly. (Rung 3) iii. If the value in V2000 is negative, we invert the bit pattern, ANDD the inverted value with KFFFF, add 1 to it, convert the positive value to REAL using BTOR, multiply by -1 and store the result in V2500. iv. It is important to note that we did not have to store the positive result in an intermediate address in this example. The result of the INV instructions is a 32 bit word stored to the accumulator. Since, we are only dealing with a 16 bit word, we need to mask (get rid of) the most significant 16 bits. To do this we use the ANDD with a value of KFFFF, which turns on only the bottom 16 bits of a 32 bit pattern. Click here for 2s complement ladder Example 2. |
