Appendix C: Modbus Viewer Program
A Modbus Viewer Program is offered as an option to allow easy Reading and Writing of CCM data located in
the Translator Modbus addresses. A Freeware version that only reads Modbus registers is available for
download from www.monicoinc.com/downloads.
Appendix D: GE Fanuc Version Notes
The GE Fanuc version gathers all Engine Data and creates a data map that is pushed to the
PLC with the Gateway acting as the Master device. In this version, like all the PLC versions,
the gains have been applied and the units have been converted to US unit. Metric Unit
versions are available upon request. This application of the gain and units conversion saves
the programmer a great deal of time because it offers the values without needed math
operations. This section is not meant to be a user guide for the PLC, just additional
information useful for use of the CDL Gateway™ with the GE Fanuc Series 90 and
Versamax Modular. If you have other GE Fanuc models, please consult the factory for
custom versions available.
Address Block Descriptions
All values are written to Analog Input Registers. This block of registers is used because they
are rarely used in the higher address ranges used by the Gateway. By starting at AI1001, we
are attempting to prevent conflicts with existing code already written in the PLC. In GE
Fanuc, there is not real difference in the Analog Input Registers and the Data Registers.
However, the Data Registers are used for all timers and counters and in some instances are
used extensively. Other Address Block ranges are available upon request.
Parameter Status Values
The four blocks for viewing which Parameters are available on your specific installation are
setup in Registers AI2001-AI2xxx. It is not normally recommended that you continually
monitor these values, but you can if so desired. After satisfactory installation, it is
recommended that you disable this device to optimize performance. You can always enable
the device in the future for troubleshooting purposes.
