A-B 1769-L32E CompactLogix Ethernet Processor

Description The Allen-Bradley 1769-L32E is the 1769 CompactLogix controller in the 5370 CompactLogix family. The controller has 750KB of internal memory, one (1) Ethernet and one (1) RS232 communication port. It supports up to sixteen (16) compact I/O modules and up to three (3) expansion libraries.

About the 1769-L32E

The CompactLogix Modular Controller, part number 1769-L32E, is a programmable automation controller (PAC) from Allen-Bradley. The controller is typically used in machine control and mid-size process applications. The controller incorporates one (1) RS232 and one (1) Ethernet communication port.

The default configuration for the RS232 interface is DF1 full duplex, 19.2 Kbps, no parity, station address 0. no handshaking, BCC error detection, auto-detect embedded response, 8 data bits and 1 stop bit. This default configuration can be manually configured to establish initial communication with the device. If used with RSLinx, autoconfiguration can be used to automatically detect communication settings. The RS232 port can also be configured as an ASCII protocol interface for connection to bar code instruments, typically used in manufacturing processes.

Ethernet communication requires an initial configuration, which can be done via BOOTP-DHCP or downloaded via the RS232 interface. When using BOOTP-DHCP, an Ethernet cable is required to connect the controller to the BOOTP host.

The Allen-Bradley 1769-L32E Compact Logix Controller is available in a unique compact cost-effective package. It incorporates one (1) EtherNet and one (1) serial communication port. It can be connected to the device via a 1747-CP3 or 1756-CP3 cable or an Ethernet cable. It has 750 KB of internal user memory, which can be expanded using the CompactFlash card part number 1784-CF128.

The 1769-L32E comes with a replaceable battery, part number 1769-BA, and supports the installation of up to 16 compact I/O modules, with up to 3 I/O groups connected via 2 expansion cables. 1769-L32E has a (5 V) DC current consumption of 850 mA, and dissipates up to 6.5 watts of heat. 1769-L32E can be easily mounted using either DIN-mounting or panel-mounting. The 1769-L32E can be easily mounted in either DIN or panel mounting, with DIN mounting having an operating shock rating of 30 G and a non-operating shock rating of 50 G, and panel mounting having an operating mode shock rating of 30 G and a non-operating mode shock rating of 50 G. The 1769-L32E can be easily mounted in either DIN mounting or panel mounting.

The 1769-L32E controller has an operating mode vibration rating of 5 G. It can withstand mounting torque forces from 1.1 to 1.8 N-m. The 1769-L32E has an operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), a storage temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit), and a non-condensing relative humidity range of 0 to 95 percent. The Logix controller has a Group 1 certified emissions (CISPA11) rating and a unique open housing. Stranded wire from 22 to 16 AWG is recommended, while solid wire should be rated from 22 to 14 AWG. The module weighs approximately 2 pounds when shipped and measures 8 x 8 x 5 inches.

The CompactLogix 1769 Series serves as a migration platform for the legacy Allen Bradley PLC family, PLC5 and SLC500. A variety of CompactLogix 1769 products, including the 1769-L32E, ensure that previous processor functionality is maintained and enhanced.

The 1769-L32E processor can accommodate up to sixteen (16) compact I/O modules. It also supports expansion by adding three (3) I/O expansion banks. The controller has 750 Kbytes of internal memory and can be connected to non-volatile memory by installing a 1784-CF64 or 1784-CF128 CompactFlash card. The controller uses the 1769-BA to retain user memory. Avoid fully discharging the batteries as this may cause the user memory (including the user programme) to be erased. Use of non-volatile memory prevents such an event.

1769-L32E Frequently Asked Questions

Is the 1769-L32E compatible with any battery?

The 1769-L32E is only compatible with the 1769-BA battery. Using other batteries (such as the 1747-BA) may cause problems.

Can I order the 1769-L32E with a warranty?

Yes, DO Supply, Inc. offers a one year warranty on the 1769-L32E.

How much memory is in the 1769-L32E?

The 1769-L32E has 750 KB of usable user memory and is compatible with the 1784-CF128 CompactFlash card for storing additional memory.

What is the power consumption of the 1769-L32E?

The current consumption of the 1769-L32E is 660 mA at 5 VDC and 90 mA at 24 VDC.

What communication capabilities does the 1769-L32E have?

The 1769-L32E has built-in communication ports for Ethernet/IP networks and serial RS-232.

How do I restore the default communication settings for the 1769-L32E controller?

The Channel 0 Default Communications button is located in the lower right corner. Use this button to change the user-defined communication settings to the controller's default communication settings. The Channel 0 Default Communications (DCH0) status indicator lights up (green, steady) to indicate that the default communications configuration is active.
