• Tasks: Handles 32 tasks with 100 programs per task

• Ethernet/IP Nodes: Supports 32 Ethernet/IP nodes

Environmental Specifications

The 1769-L33ERM operates from 0°C to +60°C (32°F to 140°F). Relative humidity tolerance ranges from 5% to 95% without condensation. Vibration rating reaches 5G from 10 to 500 Hz. Operating shock equals 20G for DIN rail mounting and 30G for panel mounting. Non-operating shock reaches 30G for DIN rail and 40G for panel mounting. Radiated RF immunity is 10 V/m with 1 kHz sine-wave 80% AM from 80 to 2000 MHz.

Power Supply Distance and Mounting

You must observe the power supply distance rating of 4. Install the 1769-L33ERM no more than four modules away from the power supply. The controller supports both DIN rail and panel mounting. Turn off the power before inserting or removing the Secure Digital (SD) card. This prevents electrical arcing and protects the module.

Communication and Network Capabilities

The embedded dual Ethernet ports support 10/100 Mbps speed with auto-negotiation. Network topologies include Device Level Ring (DLR), Star, and Linear. Configure the IP address using the BOOTP-DHCP tool. You can also download configuration via the USB 1.0 port at 12 Mbps speed. The USB port handles local communication only and cannot serve industrial data exchange.

Motion Control Integration

The Allen-Bradley 1769-L33ERM features native motion over Ethernet/IP. It supports up to Eight (8) axes of coordinated motion. Compatible drives include Kinetix 350, Kinetix 5500, Kinetix 5700, Kinetix 6500, and PowerFlex 755. These drives support position loop, velocity loop, torque loop, and frequency control applications.

Compatible I/O and Distributed Systems

This controller works with multiple distributed I/O platforms. For chassis-based I/O, compatible systems include 1746 SLC and 1756 ControlLogix. In-cabinet options feature 1734 POINT I/O, 1734D POINTBlock I/O, 1794 FLEX I/O, and 1797 FLEX Ex I/O. On-machine I/O includes 1732 ArmorBlock I/O and 1738 ArmorPOINT I/O. The 1769-L33ERM also communicates with PanelView terminals, InView message displays, SCADA, and DCS systems.

Cross-Controller Messaging

The 1769-L33ERM supports messaging with many other controllers. Compatible platforms include 1756 ControlLogix, 1756 GuardLogix, 1768-L4x CompactLogix, 1789 SoftLogix 5800, 1794 FlexLogix, PowerFlex with DriveLogix, 1785 PLC-5, 1747 SLC, and MicroLogix series (1761, 1762, 1763, 1764). This messaging capability enables data exchange when Remote I/O implementation is not feasible.
