Q: Does the 1756-L62/B include a serial communication interface?
A: Yes. It provides one RS-232 serial port supporting DF1, DH-485, ASCII, and the other specified serial communication functions.

Field Installation Guidelines

Install the 1756-L62/B in the designated ControlLogix chassis position and follow the chassis installation procedure specified for the system.

Verify the chassis power capacity against the processor backplane current requirements before energizing the system. Maintain separation between communication wiring and high-voltage or high-current conductors to reduce electrical interference.

Use appropriate grounding and shielding practices for RS-232 communication wiring. Route signal cables away from motor leads, contactors, transformers, and other significant noise sources.

Before commissioning, verify the controller identification, firmware compatibility, memory configuration, communication settings, and installed CompactFlash media. Also inspect the battery installation and connector condition before placing the processor into service.
