Internal Drive Network - Siemens SINAMICS PERFECT HARMONY GH180 Function Manual

Internal Drive Network

Overview
The internal drive network feature supports communication between a coolant system cabinet
and the drive control cabinet via an internal network.
This appendix provides information relating to this network, but this feature is not intended for
direct customer use; however, the data can be supplied to Network 1 or 2.
Description
The internal drive network is implemented as an Modbus™ Ethernet (Modbus/TCP) socket in
the NXGpro Control and is described in the pages that follow.
Network Parameters
The following parameters are used by the internal drive network and are fixed in the drive
control software:

Connector
IP Address
Ethernet Port
Network Timeout
Network Registers
The network comprises of 10 16-bit output registers (from NXGpro) and 16 16-bit input registers
(to NXGpro). The first register in each direction is a handshake register to validate network
communication for network timeout. The next 9 registers in each direction are each mapped
as 16 discrete bit values. There are also 6 16-bit analog input values in the to-drive direction.
Refer to the following table.

Input Registers (to Drive)
Note
The values of the input and output register data are dependent on the external device. Refer
to the appropriate documentation for register data definitions.
