DL260 - Our most powerful CPU

The D2-260 CPU provides all the capabilities of the other DL205 CPUs (as well as our D4-450 CPU), plus several additional features rarely found in a PLC of this size. With such an incredible array of features, you may be able to replace PLCs costing hundreds (or thousands) more. DirectSOFT5™ is used to program the D2-260. If you’re using a handheld programmer, version 2.10 (or higher) of the handheld programmer firmware is required. A few key features of the D2-260 CPU include:

Local expansion I/O
The D2-260 supports local expansion up to five total bases (one CPU base and four expansion bases). Expansion bases are commonly used when there are not enough slots available in the PLC CPU base, when the base power budget will be exceeded or when placing an I/O base at a location away from the CPU base, but within the expansion cable limits, if desired. All local and expansion I/O points are updated on every CPU scan. Each local expansion base requires the D2-CM module in the CPU slot. The local CPU base requires the D2-EM Expansion Module, as well as each expansion base.
Powerful built-in CPU communications
The D2-260 offers two communications ports that provide a vast array of communication possibilities. The top RJ-12 RS-232C port can be used for PLC programming, connection to an C-more / C-more Micro or DV-1000 operator interface panel or touchscreen, or as a K-sequence or DirectNET slave. The 15-pin bottom port (port 2) supports RS232C or RS422/RS485. This port offers several different protocol options such as: K-sequence, DirectNET Master/Slave, MODBUS RTU Master/Slave, ASCII In/Out Communications.
NOTE: Port 2 can also serve as a remote I/O master. The D2-260 supports the Ethernet Communication module and Data Communication Module for additional communications ports.
16 PID loops with auto-tuning
The D2-260 CPU can process up to 16 PID loops directly in the CPU. You can select from various control modes including automatic, manual, and cascade control. There are also a wide variety of alarms including Process Variable, Rate of Change, and Deviation. The loop operation parameters (Process Variable, Setpoint, Setpoint Limits, etc.) are stored in V-memory, which allows easy access from operator interfaces or Human Machine Interfaces (HMIs). Setup is accomplished with easy-to-use setup menus and monitoring views in the DirectSOFT5 PLC programming software. The auto tuning feature is easy to use and can reduce setup and maintenance time. Basically, the CPU uses the auto tuning feature to automatically determine near optimum loop settings.
NOTE: PID (Proportional, integral, derivative) control: Control algorithm that is used to closely control processes such as temperature, mixture, position, and velocity. The proportional portion takes care of the magnitude of the error. The derivative compensates for the rate of error change. The integral takes care of small errors over time.
Full array of instructions
The right instruction can greatly simplify your programming task and can save hours of PLC ladder logic programming time. The D2-260 supports over 225 powerful instructions, such as: Four types of drum sequencers, Leading / trailing edge triggered oneshots, Bit of word manipulation, Floating point conversions, Trigonometric functions, Table instructions, ASCII IN/OUT instructions
MODBUS RTU instructions
The D2-260 CPU supports easy-to-use MODBUS Read/Write instructions that expand our existing MODBUS network instruction capabilities. The MRX or MWX instructions allow you to enter native MODBUS addressing in your ladder logic program with no need to perform octal to decimal conversion. We added Function codes 05, 06 and the ability to read Slave Exception Codes.
These flexible instructions allow the PLC programmer to select the following parameters within one instruction window:
584/984 or 484 MODBUS data type, Slave node (0-247), Function code, MODBUS starting master / slave memory address, Number of bits, Exception code starting address

D2-250-1 CPU

The D2-250-1 offers an incredible array of features at a low cost. Release 2.1 (or higher) of the DirectSOFT™ PLC programming software is required to program the D2-250-1. Release 4.0 (or higher) is required if you intend to use local expansion I/O. If you’re using a handheld programmer, version 2.10 (or higher) of the handheld programmer firmware is required.
Following are a few key features of the D2-250-1 CPU:

Local expansion I/O
The D2-250-1 supports local expansion up to three total bases (one CPU base and two expansion bases). Expansion bases are commonly used when there are not enough slots available in the CPU base, when the base power budget will be exceeded or when placing an I/O base at a location away from the CPU base, but within the expansion cable limits. All local and expansion I/O points are updated on every CPU scan. Each local expansion base requires the D2-CM module in the CPU slot. The local CPU base requires the D2-EM Expansion Module, as well as each expansion base.
Powerful built-in CPU communications
The D2-250-1 offers two communication ports that provide a vast array of communication possibilities. The top RS232C port is for PLC programming, connection to any C-more / C-more Micro or DV-1000 panel, or to serve as a DirectNET slave. The 15-pin bottom port (port 2) supports RS232C or RS422. This port offers several different protocol options such as K-sequence, DirectNET master/slave, or MODBUS RTU master/slave. Port 2 can also serve as a remote I/O master. The D2-250 PLC supports the Ethernet Communication Module and Data Communication Module for additional communications ports.
Four PID loops with auto-tuning
The D2-250-1 CPU can process up to 4 PID loops directly in the CPU. You can select from various control modes including automatic, manual, and cascade control. There are a wide variety of alarms including Process Variable, Rate of Change, and Deviation. The loop operation parameters (Process Variable, Setpoint, Setpoint Limits, etc.) are stored in V-memory, which allows easy access from operator interfaces or HMIs. Setup is accomplished with easy-to-use setup menus and monitoring views in DirectSOFT5 programming. The auto tuning feature is easy to use and can reduce setup and maintenance time.

Full array of instructions
The D2-250-1 supports over 160 powerful instructions, such as: Four types of drum sequencers, Leading and trailing edge triggered oneshots, Bit of word manipulation, Floating point conversions, 4 PID loops
On-board memory
The D2-250-1 has 7.6 K words of flash memory on board for your program plus 7.1 K words of V-memory (data registers). With flash memory, you don’t have to worry about losing the program due to a bad battery. If you have critical data stored in the capacitor-backed V-memory, simply purchase the optional lithium battery (D2-BAT-1) to permanently maintain these parameters.
Built-in remote I/O connection
In addition to providing outstanding communications capabilities, the bottom port on the D2-250-1 PLC can also act as a master for remote I/O networks. If you need extra I/O at a remote distance from the CPU, you can use this port to add up to seven of our remote slave stations.

The D2-240 provides a subset of the D2-250-1's capabilities

If you need a good CPU with multiple communications ports and complex math or PID isn't required, then the D2-240 is the CPU for you!

Built-in memory
There is 2.5 K of EEPROM program memory in the D2-240. No additional memory is required. If you have critical data stored in the capacitor-backed V-memory, simply purchase the optional lithium battery (D2-BAT) to permanently maintain these parameters as well.
Powerful instructions
The D2-240 instructions cover most of the capability of our more powerful D2-250-1 and allow you to cover a wide variety of applications. Instructions include boolean logic, data manipulation, integer math, interrupts, subroutines, FOR/NEXT loops, and more.
Two built-in RS232C communications ports
The D2-240 PLC offers two communications ports. The top port can be used for a direct connection to a personal computer for programming, to our handheld programmer, EZTouch or EZText operator interface panels, or to the DV-1000 panel. The bottom port is a slave-only port and supports our DirectNET or K-sequence protocol at speeds up to 19.2 K baud. If you're using an operator interface or plan on connecting the system to a network later on, then you can choose the D2-240. The D2-240 also supports the D2-DCM Data Communications Module and the H2-ECOM Ethernet Communications Module.

The D2-230 is our most economical CPU for the DL205 Programmable Logic Controller product line

If you are looking at the DL205 primarily because of the size or for other reasons that don't require lots of CPU horsepower, then give the D2-230 a try.

Built-in EEPROM memory
There is 2.0 K of EEPROM program memory in the D2-230. No additional memory is required. If you have critical data stored in the capacitor-backed V-memory, simply purchase the optional lithium battery (D2-BAT) to permanently maintain these parameters as well.
One built-in communications port
The D2-230 PLC has only one communication port. If you are considering any network connections in the future, you will need the D2-240, D2-250-1, or D2-260 CPU. The extra port on those CPUs may be worth the cost, especially during machine startup or troubleshooting sessions. The D2-230 does not support the Ethernet or Data Communications modules.
Basic instruction set
The D2-230 provides a subset of the D2-240's well-rounded instructions. The D2-230's instructions cover basic boolean and simple integer math.
