  • Page 49 Modbus Register Order: Overview (also see section 4 and help file of M560 software) M560 has the facility to reorder its Modbus 3X registers to suit an existing Modbus network. The Modbus Registers Tool program provides an easy method of achieving this. The order of the registers in any node connected to the network can be read by the program by clicking on the READ button.
  • Page 50 A sample write packet will look like this:- [Node][1E][start address][No. of Double Registers][Data length in bytes] [REGISTERS][CRC(2 bytes)] It is important to remember that each register in the packet’s data field contains two references to the registers to be reordered. e.g.
