Q1: Which controllers are compatible with the 1769‑SDN?
The 1769‑SDN is compatible with CompactLogix 5370 L2 and L3 controllers (e.g., L24ER, L30ERM, L33ER, L36ER) and MicroLogix 1500 controllers. It is NOT compatible with CompactLogix 5370 L1 controllers (e.g., L16ER, L18ER) as these do not support the 1769 CompactBus architecture.
Q2: Is the 1769‑SDN still in production or has it been discontinued?
The 1769‑SDN is considered a legacy/discontinued product as Rockwell Automation has been transitioning away from DeviceNet toward Ethernet/IP. DeviceNet was officially discontinued in late 2024. The module is now only available through the used/refurbished market.
Q3: What is the difference between the 1769‑SDN and Softing 5069‑SDN?
The 1769‑SDN is Rockwell's original DeviceNet scanner for CompactLogix (legacy, discontinued). The 5069‑SDN (Softing compactLink HW‑DN) is a third‑party alternative designed for Rockwell's current 5380 controller platform, providing a migration path for users upgrading from 1769 CompactLogix while retaining DeviceNet device connectivity.
Q4: How do I configure the 1769‑SDN scanlist?
The scanlist is configured using RSNetWorx for DeviceNet software (version 3.00 or later). The software connects to the scanner via an RS‑232 DeviceNet adapter (e.g., 1770‑KFD) or PC card. After building the scanlist and mapping I/O, you download the configuration to the scanner. The controller must be in Program mode or the scanner in Idle mode to accept configuration changes.
Q5: Can I replace a 1769‑SDN with a newer module without changing my DeviceNet devices?
Yes, but options depend on your controller platform:
If staying on CompactLogix 5370: Use the 1788‑EN2DNR bridge adapter as a replacement.
If migrating to 5380 platform: The 5069‑SDN (Softing) provides in‑chassis DeviceNet connectivity.
For L1 controllers (e.g., L16ER): Use 1769‑AENTR or an external gateway (e.g., RTA 460ESDM‑N34‑D).
For long‑term sustainability, Rockwell recommends gradually migrating DeviceNet devices to Ethernet/IP equivalents.
