2.1.4.0.11. Vendor Specific Read/Write Holding Registers (73 Hex)

This service performs first write and then read operations on multiple holding registers in the Modbus
Holding Registers table. This service results in the DeviceMaster EtherNet/IP-Modbus gateway issuing a
Read/Write Holding Registers function (function code 0x17) to either the Shared Memory or the Modbus
Message Routing subsystem. Refer to MODBUS Application Protocol Specification V1.1b3.pdf at
www.modbus.org for more details.
Note: In order to use this service, the Enable Vendor Specific Modbus Object Services option on the EtherNet/
IP Stack Configuration web page must be selected.
