Product Introduction
The GE IC698RMX016 is a Remote I/O Master Adapter designed for the Series 90-70 PLC family. It serves as a communication gateway between the CPU rack and distributed I/O racks, enabling high-speed, reliable data exchange over serial backplanes. This module allows you to extend your control system physically, placing I/O modules right where you need them while keeping wiring costs and complexity down.

Typical Applications
The IC698RMX016 is widely used in industrial automation settings where distributed control is required:
-
Manufacturing Lines
Move I/O points closer to sensors and actuators on assembly or packaging lines, reducing wiring runs. -
Water/Wastewater Treatment
Monitor pump stations and remote sensors over long distances. -
Oil & Gas Processing
Deploy remote skids for temperature and pressure monitoring in hazardous locations. -
Building Automation
Control HVAC dampers, lighting, and security sensors spread across large facilities. -
Steel & Metals
Interface with distributed drives and furnace controls in harsh‐environment sections of a plant.
Key Advantages
-
Reduced Wiring Complexity
Place I/O modules near field devices; only the serial link runs back to the CPU rack. -
High Reliability
Industrial-grade design withstands 0–55 °C and high humidity. -
Modular Scalability
Add or relocate remote racks without re-wiring the entire system. -
Deterministic Performance
Guaranteed cycle times over the bus link for tightly synchronized control. -
Easy Diagnostics
Front-panel LEDs report status and communication faults instantly. -
Seamless Integration
Works transparently with Series 90-70 CPU modules and existing GE I/O cards.
Frequently Asked Questions (10)
Q1: What cabling is required between the CPU rack and the remote adapter?
A1: Use shielded, twisted-pair cable rated for 2 Mbps serial backplane communication. A Belden 9463 or equivalent is recommended.
Q2: How many remote racks can I connect to one IC698RMX016?
A2: Up to four remote racks in a daisy-chain configuration, limited by total bus length and timing requirements.
Q3: Can this module be hot-swapped during operation?
A3: No. Always power down the backplane before inserting or removing the adapter to prevent damage.
Q4: Does it support galvanic isolation?
A4: The IC698RMX016 itself is not isolated; isolation must be provided by the rack backplane or external isolators.
Q5: How do I troubleshoot communication faults?
A5: Check front-panel LEDs: a steady green “Status” LED indicates normal operation; blinking amber or red denotes errors. Use software diagnostics in Proficy Machine Edition for detailed logs.
Q6: Is there a software configuration tool?
A6: Yes—use Proficy Machine Edition Logic Developer to assign node addresses, baud rate, and scan timing.
Q7: What is the maximum cable length supported?
A7: Up to 1,200 m at 78 kbps; for higher speeds (up to 2 Mbps), keep under 200 m to maintain signal integrity.
Q8: Can it work in redundant CPU environments?
A8: Yes, the remote adapter supports redundant configurations when used with dual-bus backplanes and redundant CPUs.
Q9: Are there any firmware updates available?
A9: Firmware is built into the CPU module; updates to the backplane protocol are handled by CPU firmware upgrades. No standalone upgrade for IC698RMX016.
Q10: What certifications does this module carry?
A10: UL Listing, CE marking, and c-ULus for industrial control equipment.
