Serial Protocol and ControlLogix Backplane Operation
The MVI56E-GSC separates serial character processing from the ControlLogix processor execution environment. Each serial port supports RS-232, RS-422, or RS-485 operation through hardware selection.
The module transfers serial data through the ControlLogix backplane using configured I/O image data. Internal transmit and receive buffers accommodate larger serial data packets without requiring character-level processing in ladder logic.
The onboard 10/100 Mbps Ethernet interface provides PC-based configuration, diagnostic access, and firmware update functions. Serial communication and Ethernet configuration functions remain physically separated by their respective interfaces.
Frequently Asked Questions (FAQ)
Q: How many serial interfaces does the MVI56E-GSC provide?
A: The module provides two RJ45 serial ports, with each port configurable for RS-232, RS-422, or RS-485 operation.
Q: What backplane current does the MVI56E-GSC require?
A: The supplied specifications identify 800 mA at 5.1 VDC and 3 mA at 24 VDC.
Q: Can the module communicate with custom ASCII devices?
A: Yes. The MVI56E-GSC is designed for generic ASCII communication and custom serial protocols within ControlLogix systems.
Field Installation Guidelines
Install the MVI56E-GSC in a compatible ControlLogix chassis slot according to the applicable chassis installation procedure.
Verify the configured serial interface before connecting external equipment. RS-232, RS-422, and RS-485 wiring have different electrical reference and conductor requirements.
Route serial communication cables separately from high-current motor, contactor, and switching power conductors. Avoid parallel routing alongside high-noise conductors where practical.
For shielded serial cables, terminate the shield according to the equipment grounding architecture and applicable site standards. Avoid creating unintended ground loops through multiple shield termination points.
Verify RS-485 polarity, termination, and signal reference requirements against the connected device documentation before energizing the circuit. Do not interchange RS-232 wiring with differential RS-422 or RS-485 connections.
Confirm that the ControlLogix chassis can supply the specified module backplane current before installation. Maintain appropriate clearance and connector access for service operations.
Use the Ethernet configuration port only through the intended configuration network. Verify network addressing and firmware compatibility before performing configuration or firmware maintenance.
