About 1769-L32E
The CompactLogix modular controller with part number 1769-L32E is a Programmable automation controller (PAC) manufactured by Allen-Bradley. The controller is commonly used in machine control and medium process applications. The controller integrates one (1) RS232 and one (1) Ethernet communication port.
The default configuration of the RS232 interface is DF1 full duplex, 19.2 Kbps, no parity, station address 0, no handshake, BCC error detection, automatic detection of 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, you can use autoconfiguration to automatically detect communication Settings. The RS232 port can also be configured as an ASCII protocol interface for connecting barcode instruments, commonly used in manufacturing processes.
Ethernet communication requires initial configuration, which can be downloaded through BOOTP-DHCP or RS232 interface. When BOOTP-DHCP is used, an Ethernet cable is required to connect the controller to the BOOTP host.
The Allen-Bradley 1769-L32E Compact Logix controller comes in a uniquely compact, cost-effective package. It integrates 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 built-in user memory and can be expanded with a CompactFlash card with part number 1784-CF128.
The 1769-L32E comes with a replaceable battery and part number 1769-BA. The controller supports the installation of up to 16 compact I/O modules, and up to 3 I/O groups can be connected via 2 expansion cables. The 1769-L32E has a (5 volt) DC consumption of 850 mA and a cooling power of up to 6.5 watts. The 1769-L32E can be easily installed with DIN mounting or panel mounting. DIN mounting has a working impact rating of 30 G and non-working impact rating of 50 G, while panel mounting has a working mode impact rating of 30 G and non-working mode impact rating of 50 G.
The 1769-L32E controller has a vibration rating of 5 G in operating mode. It can withstand mounting torque forces of 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%. The Logix controller has a Group 1 Certified Emission (CISPA11) rating and features a unique open housing. Stranded wires of 22 to 16 AWG are recommended, while solid wires should be rated between 22 and 14 AWG. The module weighs about 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 series, PLC5 and SLC500. A variety of CompactLogix 1769 products, including the 1769-L32E, ensure that previous processor capabilities are maintained and enhanced.
The 1769-L32E processor can fit up to sixteen (16) compact I/O modules. It also supports scaling by adding three (3) I/O extension libraries. 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 1769-BA to reserve user memory. Avoid complete battery discharge, as this can cause user memory (including user programs) to be wiped. Using non-volatile memory prevents such events from occurring.
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) can cause problems.
How much memory does the 1769-L32E have?
The 1769-L32E has 750 KB of available user memory and is compatible with the 1784-CF128 CompactFlash card to store more memory.
What is the power consumption of the 1769-L32E?
At 5 volts DC, the 1769-L32E's current consumption is 660 mA; At 24 volts DC, the current consumption is 90 mA.
What communication capabilities does the 1769-L32E have?
The 1769-L32E has a built-in communication port for Ethernet /IP networking as well as serial RS-232.
How do I restore the default communication Settings for Controller 1769-L32E?
The default communication button for channel 0 is located in the lower right corner. Use this button to change the user-defined communication Settings to the controller's default communication Settings. If the DCH0 status indicator is on (green and stable), the default communication configuration is activated.
