A-GAGE EZ-ARRAY
Instruction Manual
Appendix
A.2 Modbus Tables
EZ-ARRAY uses the Holding Registers table for providing read-
write access to configuration data. The Holding Registers are
defined in the 40000-49999 address range. The Input Registers
table is used for providing read-only access to system status
and measurement data. The Input Registers are defined in
the 30000-39999 address range. EZ-ARRAY employs a direct
addressing scheme. For example, the input register at address
30000 is accessed by reading address 30000 (0x7530) directly
(i.e., the starting address is not an offset).
A.2.1 Holding Registers
Scan Configuration
The Scan Configuration contains the settings for the scan type
and receiver’s remote teach wire (gray wire) function.
