Question:
How can I override inputs and outputs in my DL205?
Answer
The D2-240, D2-250, D2-250-1 & D2-260 CPUs support bit override.
The D2-230 does not support override.
You must use a K-Sequence or Ethernet Link to use overrides, a DirectNet link will not support overrides
- To set the bit override option
- Go to the VIEW>OPTIONS from the DirectSOFT menu bar.
- Go to the data view tab and check bit override.
- Select Current view and New views
- From DEBUG>DATA VIEW>NEW/OPEN you can then select whether the particular bit can be (forced) overridden. When In edit mode
If you have turned bit override on for that element then you can use the on/off button to force the element.
- Inputs LEDs will not turn on when an input is overidden
- Output LEDs will turn on when overriden
You can also 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 cannot control inputs.
REMEMBER:
If you leave an override bit enabled and return the machine to service it is still in the bit override mode.
Be sure to turn override bits off before returning the PLC to service.

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.
FAQ ID: 50
Question:
When using the PID loops with my D2-250, my process variable doesn't look correct coming from my analog or temperature card. What's wrong?
Answer
The Setpoint Value (SP), Process Variable (PV), Bias (Integrator) and Control Output Value (CO) are in binary format. If you use the pointer method to bring the analog signals into the CPU be aware of the format you have specified. With the pointer method, if you do not precede the number of channels constant with an '8' the value is in BCD. You must do a BIN conversion before OUTing this value to Word+3 (PV). Also, make sure the proper format from the Word+5 (CO) is in the proper format when it reaches its module. It is in binary format when it leaves the PID loop. The loop table specifications are contained in the PID chapter of the User Manual.
FAQ ID: 51
Question:
Why can I not get any Control Output from my PID loop?
Answer
Most likely you haven't entered a high limit for your Control Output in the PID setup. The default is 0 and the maximum is 4095 binary. Your must enter something in this field (Word+31) from the PID setup or from ladder. You should also check your Control Output word (Word+5) to see if you are actually getting Control Output. If this value is changing then make sure you are writing this value to the physical output device. This will most likely be an analog card or Time-Proportioning ladder for a discrete output point.
FAQ ID: 52
Question:
Why does my Setpoint Value change in my PID loop when I go from Manual to Auto from the PID view or ladder?
Answer
You are probably in Bumpless Transfer Mode 1. In this mode, the Setpoint Value is forced to the Process Value on a manual to auto transition. You should be using Bumpless Transfer Mode 2 if you do not want this to occur. This is covered in the Bumpless Transfer section of the PID chapter in the DL205 User Manual

Question:
Is it possible to use the H0/H2/H4-ECOMS Ethernet modules with Routers on a network.
Answer
In general, assuming you only have a router or gateway, you need only give the ECOM an IP address that is valid on the remote side of the router. Sometimes you need to create a mapping in the router itself that allows IP traffic through the router to the ECOMs IP address, sometimes you need to specify the port number (0x7070), most of the times not.
Then, in DirectSOFT, when you create the link, you specify the ECOM's IP address, then your PC uses it's IP address, it's Netmask and the ECOM's IP address to determine that the ECOM is not on the local network, and it the goes to the Gateway to see if it can find the ECOM's IP address, which it can.
This process is most likely going to be different everywhere you try it. If you have a Proxy Server with the Gateway, you'll likely make a UDP mapping in the Proxy Server software to allow the traffic through. And each proxy software server package is going to be different. It can be done, but the specific information on how to do it will vary with each particular situation.
You should contact your local IT person who manages the network at your site. They should know your network's configuration and how best to make the connection function.

Question:
What is the maximum number of H2-EBC modules that the H2-ERM can support?
Answer
When Using a D2-250 or the D2-240 as the controller, the H2-ERM can support up to 16 H2-EBC units.
When the any of the Think 'N' Do Live or Studio WINPLC versions are used, the number of H2-EBC modules is limited to only one.
The WinPLC with Think & Do Live Software or Entivity STUDIO has the ability to support higher level functions such as peer-to-peer networking,PID loop control, data communications via OPC, high speed counter operations, as well as multiple serial ports via the H2-SERIO module.
As a result we request that any application that requires more than one H2-EBC base modules connected to an H2-ERM should be reviewed with the Entivity technical support manager. Therefore, the default support for the H2-ERM product is one H2-EBC per H2-ERM. While it is physically possible to go higher, there are some limitations and issues that must be understood prior to applying the product beyond one expansion base. The Entivity technical support manager can be reached at 734-205-5401.

Question:
I have a new F2-DEVNETS-1 module, but the Think 'N' Do ConnectivityCenter (or IOView) displays an error upon connection. What is causing this error?
Answer
The F2-DEVNETS-1 is a newer model of the F2-DEVNETS module. In order for this module to be used in versions Live!v5.5 or before, or Studio v7.1 or before, you must put the module in the F2-DEVNETS compatibility mode (See appendix E in the F2-DEVNETS-1 manual).
FAQ ID: 953
Question:
Do you have an adapter for the D2-DSCBL and EA-2CBL cable so that I can use them on port 2 of a DL06, DL250-1, or DL260 instead of on port 1?
Answer
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 a C-More panel, using the EA-2CBL cable.
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 EA-2CBL, or the FA-CABKIT. The FA-15HD adapter can NOT be used with the DV-1000 or the D2-HPP.

Question:
What is the format of the MWX/MRX exception buffer?
Answer
The instructions require 3 consecutive words.
If a Modbus slave device does not like something in a Modbus request it receives, it will respond with an exception response.
The exception response at the protocol level looks like:
- Byte 1 = Address Byte
- Byte 2 = Function Code of Request with Most Significant Bit Set
- Byte 3 = Exception Code
- Byte 4 and 5 = CRC Error Check Characters
These bytes are swapped in the MRX/MWX exception response buffer V-memory so:
- V-Memory 1 High Byte = Function Code Byte
- V-Memory 1 Low Byte = Address Byte
- V-Memory 2 High Byte = One of the CRC Bytes
- V-Memory 2 Low Byte = Exception Code Bytes
- V-Memory 3 High Byte = 0
- V-Memory 3 Low Byte = Other CRC Byte
The eight exception codes defined by the Modbus protocol are:
- 01 = Illegal Function Code = This slave device does not support the requested function code
- 02 = Illegal Data Address = The requested data address is not valid for this slave device
- 03 = Illegal Data Value = One of the data values in a write request is invalid for this slave device
- 04 = Slave Device Failure = Unrecoverable error in the slave device
- 05 = Acknowledge
- 06 = Slave Device Busy
- 07 = Negative Acknowledge
- 08 = Memory Parity Error
The Exception Response format and error code information comes from this document:
www.modbus.org/docs/PI_MBUS_300.pdf
Starting at page 93 (100 of 121).

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.

Question:
"CTRIO Workbench says my H2-CTRIO2 needs a firmware update" or "I updated the firwmare in my H2-CTRIO2, and now it's stuck in booter mode"
Answer
Older versions of CTRIO Workbench (2.1.x or earlier) will incorrectly identify a CTRIO2 as a CTRIO that needs a firmware update.
Do NOT attempt this. You must get the latest CTRIO Workbench version from HostEng.com (2.2.x or later).CTRIO Workbench
Unzip and install this updated version of Workbench. If you already attempted the firmware update and your CTRIO2 is now stuck in booter mode, you will need to do the same, PLUS, get the latest CTRIO2 Firmware from their website and try to update the CTRIO2 firmware again. You might have to try several times, but if it still won't get out of booter mode, you will need to contact Returns Department.

Question:
Can I use a reed switch on AC input?
Answer
We do not recommend this, as the inrush of the AC input can cause the reed switch contact to fail.
Also the reed switch can arc when opening causing a voltage higher than than your system supply.
This higher voltage can quickly damage AC inputs, which have a maximum rating of 132 vac.
Reed switch flutter or bounce can make this condition even worse.

Question:
"I can't see my ECOM(100) with NetEdit. What do I do?"
Answer
If NetEdit3 doesn't see the ECOM module when you press "Scan Network", check the following:
- Verify Link Good LEDs are illuminated on module and connecting devices like hubs or unmanaged switches.
- Turn OFF any WiFi devices or other ethernet devices.
- Firewalls need to be turned OFF for initial connection (see Windows Help). Also, turn OFF any antivirus or other protection software that can interfere with ethernet communication.
- Try to PING the ECOM module to establish basic connection (see Windows Help, or search for resources on internet if not familiar with these steps).
- You may need to disable any other network adapters besides the one physically connected to the ECOM or network the ECOM is on.
If you get "Transport Protocol error", try the instructions in this link: Host FAQ0024 Go to Step 4, Item C. The latest version of NetEdit has the ability to select the specific network adapter, by going to the main Menu, select "Network", then "Adapter" and specifying which installed adapter you want to use ( it also lists the IP addresses of the adapters). We strongly suggest you download the latest version of NetEdit
- If you have a network administrator, you may need to check with them to verify the configuration of the local network.
- If you have Windows XP or earlier, and you still can't make a connection, you should consider trying the IPX protocol. Click the IPX button in NetEdit3. If you get the 10047 error, you need to install the NWLink/IPX protocol to your computer ethernet card. See Windows Help for this procedure, or try this link Host FAQ0043
If you can't connect to an existing/unknown ECOM100 in a network, and the card is likely newer than 2007, by powering-down and putting dipswitch 6 ON, then powering up, the IP address will be reset to all 0's, and should become visible to NetEdit3. You must power down and turn this dip back OFF for card to be able to operate properly. Host FAQ0085

Question:
How can I make the CTRIO2 output wave form more stable?
Answer
Due to the 10x higher speeds of CTRIO2 modules, the waveform isn't as forgiving as a CTRIO module was.
It might be necessary to use the following circuit if you notice differences between a CTRIO and CTRIO2 module being used as a replacement.
R: 10 to 50 ohms, C: 22nF (0.022 F)
Connect the R & C in series, then connect that across the CTRIO2 outputs (preferably at the stepper's inputs instead of just right at the CTRIO2's outputs).
