Addressing
The addresses which have been received via Modbus/TCP can be modified
locally in the Modbus-TCP server. For this purpose, three registers have been
provided. The basic addresses for accessing registers, inputs and outputs are
entered into these registers. Then, the address contained in the Modbus/TCP
frame specifies the address with reference to the basic address.
Register offset
The basic address for accessing registers via Modbus/TCP is entered into
R 272702.
Register properties
Value after reset 1000000
Input offset
The basic address for accessing inputs via Modbus/TCP is entered into
R 272704.
Register properties
Value after reset 100000000
Output offset
The basic address for accessing outputs via Modbus/TCP is entered into
R 272705.
Register properties
Value after reset 100000000
The Modbus/TCP server on the JetControl receives from a Modbus/TCP client
the command read multiple registers starting from register number 100. The
number of registers to be read is 5. Register 272702 Register Offset contains
the value 1000000.
Hence, registers 1000100 through 1000104 will be read.
The Modbus/TCP server on the JetControl receives from a Modbus/TCP client
the command read input discretes specifying input number 210 and the
instruction to read this input. Register 272704
Input Offset
contains the value
100000000.
Hence, input 100000210 of a peripheral module JX3-DI16 will be read.
