Frequently Asked Questions (FAQ)

Q1: How much memory does the IC698CMX016 have?

The GE Fanuc IC698CMX016 has 16 MB of SDRAM reflective memory. Memory includes parity checking for data integrity. This memory is dedicated to reflective memory operations.

Q2: What is the maximum number of nodes on the network?

This module supports up to 256 nodes per reflective memory network. Each node requires a compatible VMIC 5565 device. Nodes connect in a daisy-chain loop configuration.

Q3: Does the IC698CMX016 require a CPU to operate?

No, this module operates independently without CPU processing. It handles all reflective memory functions on its own. This reduces load on the main CPU.

Q4: What is the maximum transmission distance?

Maximum distance is 300 meters (984 feet) using multi-mode fiber. Use LC connectors for proper termination. Keep insertion loss below 0.35 dB for reliable operation.

Q5: What software configures the IC698CMX016?

Use Proficy Machine Edition Logic Developer PLC software. Version 4.5 or later is required for full support. The CPU must have release 2.00 or higher firmware.
