GE Fanuc IC600CB513 / IC600CB516 Series Six Auxiliary I/O and CCM2 Boards
A paired page that separates the Auxiliary I/O Control function from the CCM2 communications function.
Product Overview
GE Fanuc IC600CB513 is a Series Six Auxiliary I/O Control board, while IC600CB516 is a Type 2 Communications Control Module; one extends I/O control and the other provides serial data exchange.
Both expand the CPU's reach beyond basic local control, but one manages an auxiliary I/O chain and the other provides serial communications.
IC600CB513: Auxiliary I/O Control board for the auxiliary chain.
IC600CB516: CCM2 board with multi-rail power demand and communications configuration.

Board Functions
IC600CB513 extends the Series Six CPU's control of auxiliary I/O and draws its operating load from the +5 V rack rail.
IC600CB516 is the CCM2 communications board, using the +5 V and ±12 V rails to support its processor and serial interface circuits.
IC600CB513 handles the auxiliary I/O-control role, whereas IC600CB516 provides the serial communication hardware and protocol path used by external intelligent devices.
Power and System Integration
The auxiliary I/O board consumes nine +5 V load units. CCM2 consumes seventeen +5 V units plus four units on each of the +12 V and −12 V rails.
Those different rail requirements reflect different hardware roles and must be included in the Series Six rack power calculation.
The different +5 V and ±12 V rail demands must be added to the loads of the other installed boards before the rack supply is accepted.
IC600CB513 / IC600CB516 FAQ
Can IC600CB513 replace IC600CB516?
No. CB513 controls auxiliary I/O; CB516 is a CCM2 communications board.
What is the CB513 load for IC600CB513 / IC600CB516?
The Series Six Plus table lists nine units on +5 V.
What power does CB516 require for IC600CB513 / IC600CB516?
It is listed at 17 units on +5 V and four units on each ±12 V rail.
What should be preserved for CB513 for IC600CB513 / IC600CB516?
Keep auxiliary I/O chain addresses, rack order and cable topology.
What should be preserved for CB516 for IC600CB513 / IC600CB516?
Record both port settings, protocol role, connected devices, cables and CPU program dependencies.
Which power-rail check is required for IC600CB513 / IC600CB516?
Include the +5 V load of the auxiliary I/O board and all three documented CCM2 supply-rail loads in the rack power calculation.
Auxiliary and communication boards
Mixed-function Series Six enquiries are separated by board role so an auxiliary I/O controller is not confused with a communications module.
