TRICONEX 9563-810端子板使用產品
CPU運行時連接和斷開擴展機架電纜不應嘗試運行。這將導致CPU轉到停止/停止狀態。
擴展架電源擴展架應在主機架通電的同時通電通電或應在主機架完成其安裝后通電通電初始化。當CPU運行時，不要給擴展機架通電運行通電診斷。在使用計時器（ONDTR、TMR和OFDTR）時，應注意計時器的操作不是每次掃描都調用的程序塊。
TRICONEX 9563-810端子板使用產品計時器累積時間跨越對子塊的調用，除非它們被重置。這意味著它們發揮作用就像在程序中運行的計時器，其掃描速度比程序中的計時器慢得多主程序塊。對于長時間不活動的程序塊，定時器的編程方式應考慮到這種捕獲向上特性。與此相關的是由于使用跳轉而跳過的計時器指示被跳過的計時器不會跟上，因此不會以與每次掃描相同的方式累積時間。支持固件版本1.50或更高版本的PACSystems RX7i CPU固件版本為4.05或更高版本的IC697PCM711模塊。你必須確保您正在使用正確的PCM固件版本，因為CPU無法檢查PCM的固件版本。（模塊的固件版本可以是在EEPROM的標簽上找到。）PACSystems不支持IC697PCM711的以下功能：
? 通過IC697PCM711模塊將機器版連接到CPU串行端口。
? 訪問符號變量。
? 等待模式命令。
? 不支持以下C函數：chk_genius_總線chk_genius_設備
? C函數write\u dev不會寫入只讀引用表（%S）參考、轉換位和覆蓋位）。如果嘗試此操作，呼叫將運行時失敗并返回錯誤代碼。
當將IC697PCM711與PAC系統一起使用時，以下限制適用：%部分支持W內存。只能訪問%W的偏移量0-65535通過PCM。
? 對于PACSystems，程序名當前始終為LDPROG1。
? 如果出現錯誤NACK，控制程序編號、權限級別和其他背馱狀態數據將設置為0。
? 如果PCM上運行的應用程序訪問VME總線，則該程序使用的VME地址必須更新以符合PACSystems RX7i VME尋址分配。PACSystems RX7iPACSystems RX7i用戶手冊中描述了VME地址分配VME模塊集成指南，GFK-2235。
Connection and disconnection of an expansion rack cable while the CPU is
running should not be attempted. This will cause the CPU to go to the
STOP/HALT state.
Expansion rack power Expansion racks should be powered up at the same time the main rack is
powered up or they should be powered up after the main rack has completed its
power up initialization. Do not power up an expansion rack while the CPU is
running power-up diagnostics.
Timer operation Care should be taken when timers (ONDTR, TMR, and OFDTR) are used in
program blocks that are NOT called every sweep. The timers accumulate time
across calls to the sub-block unless they are reset. This means that they function
like timers operating in a program with a much slower sweep than the timers in the
main program block. For program blocks that are inactive for large periods of time,
the timers should be programmed in such a manner as to account for this catch
up feature.
Related to this are timers that are skipped because of the use of the JUMP
instruction. Timers that are skipped will NOT catch up and will therefore not
accumulate time in the same manner as if they were executed every sweep.PACSystems RX7i CPUs with firmware versions 1.50 or later support
IC697PCM711 modules with firmware versions 4.05 or later. You must ensure
that you are using the correct firmware version of the PCM because the CPU
cannot check the PCM’s firmware version. (The module’s firmware version can be
found on a label attached to the EEPROM.)
PACSystems does not support the following for IC697PCM711:
? Connecting Machine Edition to the CPU through the IC697PCM711 module’s
serial ports.
? Access to Symbolic variables.
? WAIT mode COMMREQs.
? The following C functions are not supported:
chk_genius_bus
chk_genius_device
get_cpu_type_rev
get_memtype_sizes
get_one_rackfault
get_rack_slot_faults
? The C function write_dev will not write to read only reference tables (%S
references, transition bits, and override bits). If this is attempted, the call will
fail at run time and return an error code.
The following restrictions apply when using the IC697PCM711 with PACSystems:
%W memory partially supported. Only offsets 0-65535 of %W can be accessed
via the PCM.
? The Program Name is currently always LDPROG1 for PACSystems.
? In case of ERROR NACK, the Control Program number, privilege level and
other piggyback status data will be set to 0.
? If an application program running on the PCM accesses the VME bus, the
VME addresses being used by that program must be updated to agree with
the PACSystems RX7i VME addressing assignments. PACSystems RX7i
VME address assignments are described in the PACSystems RX7i User’s
Guide to Integration of VME Modules, GFK-2235.
