PROFACE 2880065-01模块使用方法教程
在RX7i版本6.71之前，Modbus RTU从协议将返回在收到带有无效或未定义的函数代码。从Rel 6.71开始，Modbus RTU从设备忽略具有无效或未定义函数代码的请求，并且不响应发送。
用户中现在提供的块名称应用程序故障在以前的固件版本中，非致命应用程序故障的故障条目（用于例如，参考超出范围）提供了数字信息来识别逻辑导致错误的块。然而，用户没有办法关联带有块名称的数字信息。新固件包括故障条目中块名称的前12个字符。
PROFACE 2880065-01模块如果试图下载包含以下内容的C块，则5.00版或更高版本中C块中的未定义符号未定义符号，下载将失败。机器版将显示反馈区中的以下消息：错误8097：控制器错误–控制器
已中止请求[0x05][0xFF]在5.00版之前，包含未定义符号的C块可以已成功下载，但如果执行，CPU将转换为停止/停止模式。
串行输入/输出缓冲区的长度（5.0版或更高版本）“设置输入缓冲区功能”将始终分配一个包含2049字节的缓冲区。这比以前的PAC系统多了一个字节发布。main中只允许一个BTM支架
主机架中只允许有一个BTM。主机架中的多个BTM将导致未定义的操作。
使用升级固件机架中的模块使用WinLoader实用程序升级CPU固件的过程可能会失败当主机架、远程机架或扩展机架中有多个IO模块时，由于重启机架系统所需的时间。如果升级过程失败，请移动将CPU安装到没有IO模块的机架上，并重新启动升级过程。服务请求13命令块必须包含零当服务请求功能块用于调用服务请求13时，命令块的第一个字设置要执行的最后扫描数。如果该字的值为-1（或0xFFFF），则最后扫描的次数设置为配置中的值。更改的IP地址以太网接口有联系的将具有新IP地址的硬件配置存储到RX7i，同时通过以太网连接将成功，然后立即断开连接，因为RX7i现在使用的IP地址与程序员不同。您必须输入之前CME检查器窗口中目标属性中的新IP地址正在重新连接。
Prior to Release 6.71 for the RX7i, the Modbus RTU slave protocol would return
an Invalid Function Code error response (1) upon receipt of a request with an
invalid or undefined function code. Starting with Rel 6.71, the Modbus RTU slave
ignores requests with an invalid or undefined function code, and no response is
sent.
Block name now provided in User
Application faults
In previous firmware versions, the fault entry for a non-fatal application fault (for
example, reference-out-of-range) provided numeric information to identify the logic
block causing the error. However, the user did not have a way to correlate the
numeric information with the name of the block. The new firmware includes the
first 12 characters of the block name in the fault entry.
Undefined symbols in C Blocks In Release 5.00 or later, if an attempt is made to download a C block containing
undefined symbols, the download will fail. Machine Edition will display the
following message in the Feedback Zone: Error 8097: Controller Error – Controller
aborted the request [0x05][0xFF]
Prior to Release 5.00, C blocks containing undefined symbols could be
successfully downloaded, but if they were executed the CPU would transition to
Stop/Halt mode.
Length of Serial I/O buffer (Release 5.0 or later) The "Set Up Input Buffer Function" will always allocate a
buffer containing 2049 bytes. This is one byte more than previous PACSystems
releases.
Only one BTM allowed in main
rack
Only one BTM is allowed in the main rack. Multiple BTMs in the main rack will
result in undefined operation.
Upgrading firmware with
modules in rack
The process of upgrading the CPU firmware with the WinLoader utility may fail
when multiple IO modules are in the main, remote or expansion racks, due to the
time it takes to power cycle the rack system. If the upgrade process fails, move
the CPU to a rack without IO modules and restart the upgrade process.
Service Request 13 command
block must contain zero
When the Service Request function block is used to invoke Service Request 13,
the first word of the command block sets the number of last scans to be executed.
If the value of that word is -1 (or 0xFFFF), then the number of last scans is set to
the value in the configuration.
Changing IP Address of
Ethernet interface while
connected
Storing a hardware configuration with a new IP address to the RX7i while
connected via Ethernet will succeed, then immediately disconnect because the
RX7i is now using a different IP address than the Programmer. You must enter a
new IP address in the Target Properties in the CME Inspector window before
reconnecting.
