GFD233A 3BHE022294R0101控制系统分布体系
支持固件版本1.50或更高版本的PACSystems RX7i CPU固件版本为4.20或更高版本的IC697CMM711模块。你必须确保您使用的是正确的CMM固件版本因为CPU无法检查CMM的固件版本。（模块的固件版本可以在附在模块的EEPROM。）
PACSystems不支持IC697CMM711的以下功能：
▪ 通过CMM将Machine Edition连接到CPU串行端口。
▪ 访问符号变量存储器。
▪ 等待模式COMMREQ。
▪ 永久数据报。
使用IC697CMM711和PAC系统：▪ 部分支持访问%W内存引用。只有可以通过CMM访问%W的偏移量0-65535。
▪ 程序名称当前始终为LDPROG1PAC系统。
▪ 读取和写入当前配置的引用表以外的内容限值将报告微小的代码错误90（REF_OUT_OF_RANGE）而不是F4（无效参数）如90-70系列所述。
▪ 如果出现错误NACK，控制程序编号、权限level和其他piggyback状态数据将设置为0。
▪ PACSystems CPU返回90-70的主要/次要类型CPX935（主要类型12，次要类型35）至CMM刮板与CMM通信时的内存。
▪ 控制程序编号将在PACSystems中返回为01而不是Series 90-70上报告的FF。
▪ 如果您的RX7i应用程序需要访问双端口CMM内存，使用总线读取和写入功能。
访问CMM时，在功能块设置为1。
对于CMM，区域1预定义为模块的整个双端口内存
注：有关IC697CMM711操作的详细信息，请参阅串行通信用户手册，GFK-0582 PACSystems RX7i CPU，固件版本1.50或更高版本支持DLAN接口，固件版本3.00的IC697BEM763模块或更高版本。您必须确保使用的是有效版本的DLAN固件，因为CPU无法检查DLAN的固件版本（可在标签上找到模块的固件版本连接到EEPROM。）
如果您的RX7i应用程序需要访问DLAN的双端口内存，使用总线读取和写入功能。
访问时DLAN模块，将功能块上的Region参数设置为1。
（对于DLAN模块，区域1预定义为模块的整个双端口内存。）
DLAN仅在主RX7i机架中受支持。它不受支持在扩展机架中。
注：DLAN接口模块是一个专用模块可利用性如果您有DLAN系统，请参阅DLAN/DLAN+接口模块用户手册，GFK-0729细节。
背板通信窗口设置和天才冗余使用Genius Redundancy时，不要设置背板通信窗口计时器设置为0。
同时确保留出足够的时间用于在使用Constant时运行背板通信窗口扫描模式。
充足的背板通信窗口时间必须为可供GBC交换有关Genius设备的信息丢失和添加的。
PACSystems RX7i CPUs with firmware versions 1.50 or later support
IC697CMM711 modules with firmware versions 4.20 or later. You must
ensure that you are using the correct firmware version of the CMM
because the CPU cannot check the CMM’s firmware version. (The
module’s firmware version can be found on a label attached to the
module’s EEPROM.)
PACSystems does not support the following for an IC697CMM711:
▪ Connecting to Machine Edition to the CPU through the CMM’s
serial ports.
▪ Access to Symbolic variables memory.
▪ WAIT mode COMMREQs.
▪ Permanent datagrams.
The following restrictions apply when using the IC697CMM711 with
PACSystems:
▪ Access to %W memory references is partially supported. Only
offsets 0—-65535 of %W can be accessed via the CMM.
▪ The Program Name is currently always LDPROG1 for
PACSystems.
▪ Reads and writes beyond currently configured reference table
limits will report a minor code error of 90
(REF_OUT_OF_RANGE) instead of F4 (INVALID_PARAMETER)
as reported on the Series 90-70.
▪ In case of ERROR NACK, the Control Program number, privilege
level and other piggyback status data will be set to 0.
▪ PACSystems CPUs return the major/minor type of the 90-70
CPX935 (major type 12, minor type 35) to the CMM scratch pad
memory when communicating with a CMM.
▪ Control Program Number will be returned as 01 in PACSystems
instead of FF as reported on the Series 90-70.
▪ If your RX7i application program needs to access the dual port
memory of a CMM, use the BUS READ and WRITE functions.
When accessing the CMM, set the Region parameter on the
function block to 1. (For the CMM, region 1 is predefined to be the
module's entire dual port memory.)
Note: For details on operation of the IC697CMM711, refer to the
Serial Communications User’s Manual, GFK-0582 PACSystems RX7i CPUs with firmware versions 1.50 or later support
DLAN Interface, IC697BEM763 modules with firmware versions 3.00
or later. You must ensure that you are using a valid version of the
DLAN firmware because the CPU cannot check the DLAN’s firmware
version. (The module’s firmware version can be found on a label
attached to the EEPROM.)
If your RX7i application program needs to access the DLAN’s dual port
memory, use the BUS READ and WRITE functions. When accessing a
DLAN module, set the Region parameter on the function block to 1.
(For the DLAN module, region 1 is predefined to be the module's entire
dual port memory.)
The DLAN is only supported in the main RX7i rack. It is not supported
in expansion racks.
Note: The DLAN Interface module is a specialty module with limited
availability. If you have a DLAN system, refer to the
DLAN/DLAN+ Interface Module User’s Manual, GFK-0729 for details.
Backplane Comm window setting and Genius redundancy
When using Genius Redundancy, do not set the backplane
communications window timer to 0. Also be sure to allow enough time
for the backplane communications window to run when using Constant
Sweep mode. Ample backplane communications window time must be
available for the GBCs to exchange information about Genius devices that are lost and added.
