CPU SpecificationsDL330/DL330P/DL340CPU DL330/DL330P/DL340 CPU SpecificationsOverviewThe CPU is the heart of the control system. Almost all system operations arecontrolled by the CPU, so it is important that it is set-up and installed correctly. Thischapter provides the information needed to understand:S the differences between the different models of CPUsS the different memory optionsS the steps required to setup and install the CPU.The DL330 modular CPU is capable of controlling 176 I/O points and has 3.7K wordsof program storage. This CPU supports the RLL programing language and can saveprograms internally to RAM or UVPROM. There is a built-in programming port thatdirectly supports the handheld programmer.DL330 CPUFeaturesDL330P CPUFeaturesThe DL330P modular CPU is capable of controlling 176 I/O points and has 3.7Kwords program storage. This CPU supports the RLL PLUS programing language andcan save programs internally to RAM or UVPROM. RLL PLUS provides a structuredprogramming environment for Relay Ladder Logic through the addition of stagelogic. There is a built-in port that directly supports the handheld programmer.DL340 CPUFeaturesThe DL340 modular CPU is capable of controlling 184 I/O points and has 3.7K wordsprogram storage. This CPU supports the RLL programming language and can saveprograms internally to RAM, UVPROM or EEPROM. There is a handheldprogramming port and two built-in RS232C ports for PC programming, operatorinterfaces, or networking. If you are using the DL340 in a DirectNET network, youcan use either port as a slave port and the bottom port as a master. The bottom porthas the additional capability of being configured as a slave on a Modbus network.CPU Hardware FeaturesCPU Status IndicatorsRUNONOFFCPU is in RUN modeCPU is in Program modeBATTONOFFMemory backup voltage lowMemory backup voltage goodONOFFCPU failure (Error detected when thewatchdog timer is not processed within100ms.

DL330/DL330P/DL340 CPU SpecificationsSelecting CPU Memory OptionsInternal RetentiveMemoryIn addition to different choices for program storage, you can also select somememory areas to be retentive. Retentive memory retains its state after a power cycleor a program to run transition occurs, as long as the memory backup battery isfunctional. Non--retentive memory resets to a logical “0” after a power cycle or aprogram to run transition occurs. You have to use dipswitch to select the retentivememory options (the switches are discussed in the next section.)The following table shows the how the types of memory are defined. Some types ofmemory are automatically defined as retentive and other memory types can bedefined as retentive as necessary for your application. The types of memoryavailable depend on the type of CPU selected for your application.Retentive MemoryPre--definedApplication programYesUser definedStages (DL330P only)YesInternal relaysYesCurrent count valuesYes (full range)Shift register bitsYes (full range)Data registersYes (full range)PasswordYesExternal ProgramStorageAll DL305 CPUs allow for program storage to be captured on external media such ascassette tape, floppy disk and hard disk. Refer to the DL305 Handheld Programmermanual for details on storing the CPU program to cassette tape. The DirectSOFTmanual provides details on storing the CPU program to floppy or hard disk.Volatile andNon-volatileMemoryThere are two types of memory storage available, volatile and non-volatile. Volatilememory will retain your data as long as proper voltage is maintained to the storagemedia. Non-volatile memory does not require power to retain data. The DL305CPUs maintain the proper voltage either through the base power supply or the use ofthe memory backup 0P/DL340CPU SpecificationsDL330/DL330P/DL340CPU DL305 User Manual, Rev. D

DL330/DL330P/DL340 CPU SpecificationsThe type of program storage memory available to you depends on the CPU you areusing. All DL305 CPUs support application program storage to either CMOS RAM orthe optional UVPROM. The DL340 has the added option of supporting programstorage in EEPROM. The application program can be up to 3.7K words.S CMOS RAM memory (Random Access Memory) is standard on all theDL305 CPUs. It is a volatile memory which can be modified or changedeasily with a handheld programmer or PC programming software.S UVPROM (Ultraviolet Programmable Read Only Memory) is optional forall the DL305 CPUs. This type of memory is non--volatile and can onlybe erased with an ultraviolet light source. The PROM Writer Unit(D3--PWU) is used to copy your application program from the CPU’sRAM to a UVPROM. If the UVPROM has a program to be changed, itmust be removed from the CPU and erased before another program canbe copied on the UVPROM.S EEPROM (Electrically Erasable Programmable Read Only Memory) isan option only on the DL340 CPU. This type of memory is non--volatile,but can be electrically erased. The EEPROM can be electricallyreprogrammed without being removed from the CPU, and without theuse of a special external programming device.DL330/DL330P/DL340SpecificationsWARNING: Be sure to use proper grounding techniques when touchingUVPROMS and EEPROMS. A static discharge from you may cause damage tothe PROM. If you do not have a ground strap, then ground yourself bytouching the controller chassis before you make contact with the PROM. Alsoensure that the surface where you place the PROM is properly grounded.DL330/DL330P/DL340CPU SpecificationsProgram StorageMemory Types(Internal)3--5DL330/DL330P/DL340CPU 5 User Manual, Rev. D

DL330/DL330P/DL340 CPU SpecificationsThe PROM Writer Unit connects directly to either a DL330, DL330P or DL340 CPU.Use the following steps to connect the PROM Writer Unit:1. Set the power supply source switch (on the back of the unit) to theappropriate power source setting, (INT for using base power and EXT foran external power source). The PROM Writer Unit can either use the localCPU base power or use an external power source.NOTE: If you are using the local CPU base power you will need to includethe Prom Writer Unit power consumption in your power budget. The powerbudget is covered in Chapter 4.DL330/DL330P/DL340CPU 5 User Manual, Rev. DDL330/DL330P/DL340CPU Specifications2. If using an external power source attach the supplied cable to the powersource socket on the back of the unit. The white wire should be connectedto 5VDC and the black wire should be connected to DC ground.3. Turn off the power source to the base before attaching the PROM WriterUnit.4. Attach the PROM Writer Unit to the CPU. The connector on the back of theunit will mate with the programming port (PRG) of the CPU. Tighten thefixture screw to secure the two units together.5. Apply power to the local CPU base and if necessary to the PROM WriterUnit. Once the PWR LED is on it will take approximately 10 seconds for theunit to initialize. During this time keystrokes will not be recognized.Copying a Program The following steps explain how to copy a program from the CPU RAM to aFrom the CPU RAM UVPROM:1. Turn power on.to a UVPROM2. Raise the UVPROM socket lever.3. Insert the UVPROM (notch up) in the socket and lower the lever.4. Press the “WRITE” button. The following sequence of events will takeplace:S The WRITE LED will turn on then off.S The BLANK LED will come on. (This notes the checking sequence toensure that the UVPROM is blank has started.)S The BLANK LED will turn off and the WRITE LED will turn on.S The WRITE LED will turn off and the VERIFY LED will turn on. (Thisindicates that the write is complete. While the VERIFY LED is on, acomparison between the UVPROM and the CPU RAM is beingmade.)S The VERIFY LED will turn off. (This indicates the end of the copyingfunction.)S If an error has been detected, the ERR LED will come on. If thishappens press the “ERR” key to clear the error and the “WRITE” keyto repeat the procedure. If this does not correct the problem, repeatthe procedure using a different UVPROM.5. Turn power off, raise the UVPROM socket lever and remove UVPROM.DL330/DL330P/DL340SpecificationsSetting up thePROM Writer Unit3--7

Turn power off, raise the UVPROM socket lever and remove UVPROM.Erasing a UVPROM UVPROMS can be erased through exposure to an ultraviolet light source. Make surethat the window to the UVPROM is not covered so that it may receive full exposure tothe light source. A typical exposure would be: 12,000μ w/cm2 lamp @ 2.5 cm for15--20 0P/DL340CPU SpecificationsDL330/DL330P/DL340CPU SpecificationsComparing aProgram From theUVPROM to theCPU RAMDL305 User Manual, Rev.
