GFD233A 3BHE022294R0101控制系統分布體系

支持固件版本1.50或更高版本的PACSystems RX7i CPU固件版本為4.20或更高版本的IC697CMM711模塊。你必須確保您使用的是正確的CMM固件版本因為CPU無法檢查CMM的固件版本。（模塊的固件版本可以在附在模塊的EEPROM。）

PACSystems不支持IC697CMM711的以下功能：

? 通過CMM將Machine Edition連接到CPU串行端口。

? 訪問符號變量存儲器。

? 等待模式COMMREQ。

? 永久數據報。

使用IC697CMM711和PAC系統：? 部分支持訪問%W內存引用。只有可以通過CMM訪問%W的偏移量0-65535。

? 程序名稱當前始終為LDPROG1PAC系統。

? 讀取和寫入當前配置的引用表以外的內容限值將報告微小的代碼錯誤90（REF_OUT_OF_RANGE）而不是F4（無效參數）如90-70系列所述。

? 如果出現錯誤NACK，控制程序編號、權限level和其他piggyback狀態數據將設置為0。

? PACSystems CPU返回90-70的主要/次要類型CPX935（主要類型12，次要類型35）至CMM刮板與CMM通信時的內存。

? 控制程序編號將在PACSystems中返回為01而不是Series 90-70上報告的FF。

? 如果您的RX7i應用程序需要訪問雙端口CMM內存，使用總線讀取和寫入功能。

訪問CMM時，在功能塊設置為1。

對于CMM，區域1預定義為模塊的整個雙端口內存

注：有關IC697CMM711操作的詳細信息，請參閱串行通信用戶手冊，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模塊或更高版本。您必須確保使用的是有效版本的DLAN固件，因為CPU無法檢查DLAN的固件版本（可在標簽上找到模塊的固件版本連接到EEPROM。）

如果您的RX7i應用程序需要訪問DLAN的雙端口內存，使用總線讀取和寫入功能。

訪問時DLAN模塊，將功能塊上的Region參數設置為1。

（對于DLAN模塊，區域1預定義為模塊的整個雙端口內存。）

DLAN僅在主RX7i機架中受支持。它不受支持在擴展機架中。

注：DLAN接口模塊是一個專用模塊可利用性如果您有DLAN系統，請參閱DLAN/DLAN+接口模塊用戶手冊，GFK-0729細節。

背板通信窗口設置和天才冗余使用Genius Redundancy時，不要設置背板通信窗口計時器設置為0。

同時確保留出足夠的時間用于在使用Constant時運行背板通信窗口掃描模式。

充足的背板通信窗口時間必須為可供GBC交換有關Genius設備的信息丟失和添加的。

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.
