RF533 3BSE014227R1提供船舶运输模块
SU Lifelist心跳：此参数定义将SU生存列表发送到MCU的时间间隔。“车站”
MCU上的Lifelist Timeout’参数监控SU Lifelist的接收。
控制访问优先级：
参数为CA机制中的主干设备分配优先级顺序。CA机制以分级方式工作。层次结构根据分配给设备的优先级进行维护。这个然后根据优先级顺序处理控制访问。最多可以为优先级定义16个站点顺序CA优先级为1的电台具有最高优先级，CA优先级为16的电台为最低的那个。CA优先级应分配给每个设备唯一。
控制访问名称：此参数中指定的名称用于MCU CAT。因此，名称表示CAT.类别。
3.2.3设备数据
设备数据显示MMI、网关和INSUM OS等背板设备的当前版本。这个信息直接从设备读取，仅供用户参考。
固件版本：此字段中的数据显示设备的固件版本及其发布日期。这样，用户可以确认设备上现有的版本。这也可以在升级软件时用作检查。
如果升级成功，该字段将显示升级的软件版本。
此字段特定于MMI和网关。此字段中的数据显示设备的硬件版本。这样，用户可以确认版本设备上存在。在升级设备到新软件版本。
参数文件版本：
此字段中的数据显示设备的参数文件版本。这样，用户可以确认所用参数文件的正确性。
重要的工厂新网关使用默认参数。如无必要，不应更改这些内容。
更改参数后，使用重置按钮重新启动网关：PROFIBUS地址或/和子网筛选器。否则，网关将无法使用新设置。NSUM PROFIBUS DP协议PROFIBUS区分主设备和从设备。主设备决定数据总线上的通信。
在PROFIBUS协议中，主机也称为活动站，可以发送当它拥有总线访问权限即令牌时，没有外部请求的消息。从属设备，也被称为无源设备没有总线访问权限，只能确认收到消息或在请求时向主机发送消息。
INSUM PROFIBUS网关是一个PROFIBUS-从设备，当来自主站，即正在接收PCS。
4.2 GSD文件
关于如何在PCS系统中将INSUM PROFIBUS网关配置为PROFIBUS-从机的信息在PROFIBUS标准规定的网关GSD数据文件中描述。*。GSD文件是一个文本文件包含PROFIBUS设备的描述，具有预定语法。INSUM的内容PROFIBUS网关对于PCS系统中PROFIBUS-从设备的配置至关重要。
SU Lifelist Heartbeat:
This parameter defines the time interval at which the SU lifelist is to be sent to the MCU's. The 'Station
Lifelist Timeout' Parameter on the MCU monitors the receipt of SU lifelist.
Control Access Priority:
This parameter assigns the priority order to the backbone device in CA mechanism. The CA mechanism
works in a hierarchical manner. The hierarchy is maintained as per the priority assigned to the device. The
Control Access is then handled based on the priority order. Up to 16 stations can be defined for the priority
order. The station defined with a CA priority 1 has the highest priority and the station with CA priority 16 is
the lowest one. The CA priority should be assigned unique to every device.
Control Access Name:
The name assigned in this parameter is used in the MCU CAT. The name thus represents the device in the
CAT.
3.2.3 Device Data
The Device Data show the current versions of backplane devices like MMI, Gateway, and INSUM OS. The
information is directly read from the devices and is for user information only.
Firmware Version:
The data in this field shows firmware version of the device with it's date of release. With this, the user can
confirm the version existing on the device. This can also be used as a check while upgrading the software.
The field will show the upgraded software version if the upgrade is successful.
This field is specific to MMI and Gateway.The data in this field shows hardware version of the device. With this, the user can confirm the version
existing on the device. This can also be used as a compatibility check of hardware while upgrading the
device to new software release.
Parameter File Version:
The data in this field shows parameter file version of the device. With this, the user can confirm the
correctness of a parameter file used.
Important
A new gateway from factory uses default parameters. Those should not be changed if not necessary.
Reboot gateway by using of Reset Push Button after a change of parameters: PROFIBUS address or/ and
subnet filter. Otherwise gateway will not work with new settings.NSUM PROFIBUS DP Protocol
PROFIBUS distinguishes between Master and slave devices. Master devices determine the data
communication on the bus. A master, also called active stations in the PROFIBUS protocol, can send
messages without an external request when it holds the bus access rights i.e. token. Slave devices, also
referred as passive devices do not have bus access rights and they can only acknowledge received
messages or send messages to the master as and when requested.
The INSUM PROFIBUS Gateway is a PROFIBUS slave device that responds when a query from the
Master station i.e. PCS is being received.
4.2 GSD-File
The information on how to configure the INSUM PROFIBUS Gateway as PROFIBUS slave in PCS system
is described in the Gateway GSD data file as specified by PROFIBUS standard. The *.GSD file is a text file
containing description of the PROFIBUS device, with a predetermined syntax. The content of the INSUM
PROFIBUS Gateway is important for the configuration of PROFIBUS slave device in PCS system.
