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. 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.
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 your User Manual.
FAQ ID: 53

Question: Can the DL205 expand beyond the local rack?
Answer: The D2-250-1 and D2-260 CPUs can be expanded using the D2-EM and D2-CM modules.
See the DL205 User's Manual, Local Expansion I/O in Chapter 4 for details.
Another method the I/O can be expanded is by adding remote I/O with the D2-240, D2-250, D2-250-1 and D2-260.
    The D2-240 uses the D2-RMSM (Remote Master) module.
  • A total of 896 I/O points are available by using 2 Remote Master modules with 7 slave per module.
    The D2-250 and higher uses either the D2-RMSM module or the bottom port of the CPU.
  • A total of 2048 I/O points are available using up to 7 Remote Master modules and the CPU port with 7 slaves per module and the CPU.
The D2-230 can not be expanded beyond the local rack.
FAQ ID: 54

Question: Can the DL205 communicate to the DL305 or DL405 CPU's?
Answer: Yes, the DL205 CPU's can communicate with the DL305 and DL405 CPU's. The D2-230 can be a slave using the D2-DCM (Data Communications Module). The D2-240 can be a master/slave by using the D2-DCM or the H2-ECOM(-F) (Ethernet Communication Module). Also, the D2-240 can be a slave by using the bottom port on the CPU. The D2-250-1 and D2-260 can be a master/slave by using either the D2-DCM, the bottom port on the CPU or the H2-ECOM(-F).
FAQ ID: 55

Question: Which DL205 CPUs support the Power Up in Run Mode feature?
Answer: Only the D2-230. If you set bit Bit 13 of V-memory 7633, the D2-230 will power-up in Run provided the CPU does not encounter any errors. The D2-250-1 AND D2-260 have a Run/Term/Stop switch. The D2-240 has a Run/Term switch. In the Run position the CPU is forced into the Run mode if no errors are encountered. No changes are allowed by the attached programming/monitoring device. In the Term position, Run, Program and the Test modes are available. Mode and program changes are allowed by the programming/monitoring device. In the Stop position (D2-250-1 and D2-260 only), the CPU is forced into the Stop mode. No changes are allowed by the attached programming/monitoring device.
FAQ ID: 56

FAQ ID: 60

Question: I need to add another module to my DL205 9-slot base, but the rack is full. What can I do?
Answer: 1.- D2-250-1 and D2-260 are the only CPUs supporting local expansion. You need to change the base D2-09B to D2-09B-1 if this is the case. 2.- You can use ERM/EBC system with all CPUs except D2-230. 3.- A D2-RMSM with a D2-240, a D2-250 and a D2-260, or the bottom port of a D2-250(1) or D2-260 CPU can serve as a remote I/O master. The D2-RSSS serves as the remote slave and resides in the CPU slot of the remote base. Since this is true remote I/O, the scan is handled differently than local I/O.The D2-230 does not support remote I/O.
FAQ ID: 61

Question: Can the DL205 be used on a Modbus network?
Answer: The D2-240, D2-250-1 and D2-260 can be used on a Modbus network. The D2-250-1 and D2-260's bottom port can be set to Modbus master/slave. Also, the DCM module can act as a Modbus slave when used with the D2-240 or D2-250 or D2-250-1 or D2-260. The Modbus RTU (hex) protocol is supported. The D2-230 cannot be used on a Modbus network.

FAQ ID: 806

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. But let me stress that 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 will need to get the person who manages the network at each site to figure out how his/her network must be configured to allow this to work.
FAQ ID: 903

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: 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.

Question: What is the format of the MRW/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).
