Selecting CPU Memory Options
Internal Retentive
Memory
In addition to different choices for program storage, you can also select some
memory areas to be retentive. Retentive memory retains its state after a power cycle
or a program to run transition occurs, as long as the memory backup battery is
functional. Non--retentive memory resets to a logical “0” after a power cycle or a
program to run transition occurs. You have to use dipswitch to select the retentive
memory options (the switches are discussed in the next section.)
The following table shows the how the types of memory are defined. Some types of
memory are automatically defined as retentive and other memory types can be
defined as retentive as necessary for your application. The types of memory
available depend on the type of CPU selected for your application.

External Program
Storage
All DL305 CPUs allow for program storage to be captured on external media such as
cassette tape, floppy disk and hard disk. Refer to the DL305 Handheld Programmer
manual for details on storing the CPU program to cassette tape. The DirectSOFT
manual provides details on storing the CPU program to floppy or hard disk.
Volatile and
Non-volatile
Memory
There are two types of memory storage available, volatile and non-volatile. Volatile
memory will retain your data as long as proper voltage is maintained to the storage
media. Non-volatile memory does not require power to retain data. The DL305
CPUs maintain the proper voltage either through the base power supply or the use of
the memory backup battery.

DL305 User Manual, Rev. D
DL330/DL330P/DL340 CPU Specifications
The type of program storage memory available to you depends on the CPU you are
using. All DL305 CPUs support application program storage to either CMOS RAM or
the optional UVPROM. The DL340 has the added option of supporting program
storage in EEPROM. The application program can be up to 3.7K words.
S CMOS RAM memory (Random Access Memory) is standard on all the
DL305 CPUs. It is a volatile memory which can be modified or changed
easily with a handheld programmer or PC programming software.
S UVPROM (Ultraviolet Programmable Read Only Memory) is optional for
all the DL305 CPUs. This type of memory is non--volatile and can only
be erased with an ultraviolet light source. The PROM Writer Unit
(D3--PWU) is used to copy your application program from the CPU’s
RAM to a UVPROM. If the UVPROM has a program to be changed, it
must be removed from the CPU and erased before another program can
be copied on the UVPROM.
S EEPROM (Electrically Erasable Programmable Read Only Memory) is
an option only on the DL340 CPU. This type of memory is non--volatile,
but can be electrically erased. The EEPROM can be electrically
reprogrammed without being removed from the CPU, and without the
use of a special external programming device.
DL330/DL330P/DL340
Specifications
WARNING: Be sure to use proper grounding techniques when touching
UVPROMS and EEPROMS. A static discharge from you may cause damage to
the PROM. If you do not have a ground strap, then ground yourself by
touching the controller chassis before you make contact with the PROM. Also
ensure that the surface where you place the PROM is properly grounded.

The 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 the
appropriate power source setting, (INT for using base power and EXT for
an external power source). The PROM Writer Unit can either use the local
CPU base power or use an external power source.
NOTE: If you are using the local CPU base power you will need to include
the Prom Writer Unit power consumption in your power budget. The power
budget is covered in Chapter 4.

2. If using an external power source attach the supplied cable to the power
source socket on the back of the unit. The white wire should be connected
to +5VDC and the black wire should be connected to DC ground.
3. Turn off the power source to the base before attaching the PROM Writer
Unit.
4. Attach the PROM Writer Unit to the CPU. The connector on the back of the
unit will mate with the programming port (PRG) of the CPU. Tighten the
fixture screw to secure the two units together.
5. Apply power to the local CPU base and if necessary to the PROM Writer
Unit. Once the PWR LED is on it will take approximately 10 seconds for the
unit to initialize. During this time keystrokes will not be recognized.

Port 1 (RS232C): Network address selection is accomplished with the Network Address
Mode Switch and the two rotary switches 3 and 4. The address is set in BCD.
Network Address Mode Switch sets fixed or selectable network address.
Rotary Switch 3 sets the least significant decimal digit of the network address.
Rotary Switch 4 sets the most significant decimal digit of the network address.
In the example above, when the Network mode switch is set to FIXED the network
address will default to 01, when the Network mode switch is set to USER the network
address (set with the rotary switches) is 03. Note, if the rotary switches are set to 00, the
network address will default to 01.
Port 2 (RS232C): Network address selection is set by using a programming device to
enter the value for the most significant digit and least significant digit in addresses R771
and R772 respectively. The address is set in BCD.
If you’re using MODBUS RTU protocol on Port 2, the MODBUS address is set in
decimal, not BCD. Load the lower two digits in R771 and the upper two digit(s) in R772.

You can use the Handheld Programmer or DirectSOFT to select an on and off
response delay time of up to 1980 ms. The time delay is calculated based on a preset
number that is loaded into two memory locations. These presets indicate the number
of 20 ms intervals that will be used as the delay. For example, an entry of 2 would
result in a 40 ms response delay time.

Backup
The DL305 CPUs have a lithium battery to retain the application program and
retentive memory when the system is not receiving power from the power supply.
Typical battery life is five years. This time period includes PLC runtime and normal
shutdown periods such as preventative maintenance and power outages.
The CPU has indicators which tell when it is necessary to change the battery.
However, if your battery has been in your system for an extended period of time, you
may wish to take added precautions to ensure that the system memory will be
retained by installing a new battery when shutting the system down for a period of
more than ten days.

CPU Setup and System Functions
A Few Things to
Know
Even if you have years of experience using PLCs, there are a few things you need to
do before you can start entering programs. This section includes some basic things,
such as changing the CPU mode and connecting a programming device. Here is a
list of the items that are discussed.
S Auxiliary Functions
S Connecting a Programming Device
S Changing the CPU Modes
S Clearing the CPU memory
The following paragraphs provide the setup information necessary to get the CPU
ready for programming. The actual setup information depends on the type of
programming device you are using. For example, the DL305 Handheld Programmer
manual provides the Handheld keystrokes required to perform all of these
operations. The DirectSOFT manual provides a description of the menus and
keystrokes required to perform the setup procedures via DirectSOFT.

Many CPU tasks involve the use of predefined functions. These are often called
Auxiliary (AUX) Functions. The AUX Functions perform many different operations,
ranging from simple operating mode changes to determining the firmware revision
number.
You can access all of the AUX Functions from DirectSOFT menu options, but not
from the DL305 Handheld Programmer. You can still perform some of the operations
with the Handheld Programmer, but they are accomplished by using a certain series
of keystrokes rather than by entering a specific AUX function.
NOTE: Neither DirectSOFT or the Handheld Programmer utilize the numbers
shown for the AUX functions. These numbers have been included because many of
you may already have existing software packages that can be used with these
CPUs. If you do already have an existing software package, remember that any
additional features (such as added I/O, CRs, etc. available with the DL340 CPU)
may not be accessible.

Connecting the
Programming
Devices
You can mount the Handheld directly to the port of the CPU, or you can use a cable.
The cable, part number D3--HPCBL, is approximately 4.5 feet (1.5m) in length and
provides more flexibility. There are two different handheld programmers for the
DL305 CPUs. The D3--HP can be used with either the DL330 or the DL340. The
D3--HPP can only be used with the DL330P. The D3--HPP supports the RLL PLUS
features.
If you’re using a Personal Computer with the DirectSOFT programming package, a
Data Communications Unit (either RS232C or RS422) must be used to interface to
the DL330/DL330P CPUs. DCUs may also be used to establish a connection
between the DL305 and an operator interface or a network.
The DL340 CPU provides two built-in RS232C ports which can be used to directly
connect to a personal computer, operator interface or network. The DCU may also
be used with the DL340 if the built-in ports are otherwise occupied.

Changing the CPU There are two modes of operation for the DL305 CPUs:
Mode of Operation
S RUN — executes the application program and updates I/O modules
S PGM — allows program entry, does not execute the application program
or update I/O modules
The CPU modes for all DL305 CPUs can be changed by using either a Handheld
Programmer or DirectSOFT. The DL330 and DL330P require a Data
Communications Unit when using DirectSOFT. This is discussed later in this
chapter.
Since the DL340 has the possibility of being accessed through multiple ports at the
same time, the Handheld Programmer and DCU have priority over the built-in
RS232C ports during mode change operations. If no Handheld Programmer or DCU
is online, DirectSOFT can perform mode changes through either of the built-in
ports. When the Handheld Programmer or DCU is online and a mode change is
attempted with DirectSOFT, the Handheld Programmer or DCU will immediately
change the mode back to the original mode. This forces the CPU mode to always
correspond with the keyswitch position on the Handheld Programmer.
WARNING: The CPU will automatically change modes when you connect the
Handheld Programmer if the keyswitch is set for a different mode of operation.
For example, if the CPU is in Run mode and the Handheld Programmer
keyswitch is set to the PRG (Program) position, the CPU will automatically
enter Program mode when the Handheld is connected.

Before you enter a new program, you should always clear the CPU memory. Only a
few keystrokes are required. The next few steps show how to clear the CPU memory
using the handheld programmer.
Put the handheld programmer’s key switch in the PRG position. Attach the handheld
programmer directly to the front of the CPU making sure that the port on the back of
the programmer aligns properly with the port on the CPU and the programmer’s
latches connect with the slots in the base power supply. Apply power to the base.
LED’s on the programmer will display indicating a good connection.
