RJ45 Connector
4.10 TCP/IP On-board Interface
The Hobart
PoWerMaster®
2400 is equipped with a
TCP/IP (RJ45) communication port for supervision and
monitoring of the Ground Power Unit (GPU) e.g. by the
means of a central computer. The port is located on the
Control Board (A1).
The protocol is limited to MODBUS TCP/IP. The data
available from the GPU are comprehensive and should
meet most requirements.
Supported Modbus Function Codes.
The Hobart
PoWerMaster®
2400 implements a
subset of the Modbus Application Protocol Specification V.1.1b.
The following function codes are supported in Modbus requests:
-
03 (0x03) Read Holding Registers
-
04 (0x04) Read Input Registers
-
06 (0x06) Write Single Register
-
16 (0x10) Write Multiple Registers
In the following section, the different kinds of data available are:
•
System in use, system in standby and system in fault.
•
The GPU provides a comprehensive range of internal and external parameter measurements and
information e.g. voltages, currents, temperatures, time, date etc.
•
The GPU provides two kinds of logs:
•
The Black Box which contains the last 100 errors detected together with all relevant
parameters and status information available in connection with a shut-down.
•
The Power log which contains the time in use and the power consumption for the last 100
operations.
Note!
Detailed information on the Modbus Communication and available parameters can found in the
document 999.008, which can be obtained from ITW GSE on request.
Refer to chapter 6.3 and section 7.19 & 7.20 for communication set-up
