Appendix A – Internal Memory Addresses
Each HMC7000 unit has internal memory which can be used for operations that do not require
data from an attached PLC. The number of memory registers available depends upon which
HMC model you have selected. Part of this memory is reserved for specific uses (see Appendix B
– Predefined System Tags) while the rest of the memory is openly available for your application.
Below is a table that defines the internal memory of the HMC7000
