TRICONEX 9563-810端子板使用产品
CPU运行时连接和断开扩展机架电缆不应尝试运行。这将导致CPU转到停止/停止状态。
扩展架电源扩展架应在主机架通电的同时通电通电或应在主机架完成其安装后通电通电初始化。当CPU运行时，不要给扩展机架通电运行通电诊断。在使用计时器（ONDTR、TMR和OFDTR）时，应注意计时器的操作不是每次扫描都调用的程序块。
TRICONEX 9563-810端子板使用产品计时器累积时间跨越对子块的调用，除非它们被重置。这意味着它们发挥作用就像在程序中运行的计时器，其扫描速度比程序中的计时器慢得多主程序块。对于长时间不活动的程序块，定时器的编程方式应考虑到这种捕获向上特性。与此相关的是由于使用跳转而跳过的计时器指示被跳过的计时器不会跟上，因此不会以与每次扫描相同的方式累积时间。支持固件版本1.50或更高版本的PACSystems RX7i CPU固件版本为4.05或更高版本的IC697PCM711模块。你必须确保您正在使用正确的PCM固件版本，因为CPU无法检查PCM的固件版本。（模块的固件版本可以是在EEPROM的标签上找到。）PACSystems不支持IC697PCM711的以下功能：
▪ 通过IC697PCM711模块将机器版连接到CPU串行端口。
▪ 访问符号变量。
▪ 等待模式命令。
▪ 不支持以下C函数：chk_genius_总线chk_genius_设备
▪ C函数write\u dev不会写入只读引用表（%S）参考、转换位和覆盖位）。如果尝试此操作，呼叫将运行时失败并返回错误代码。
当将IC697PCM711与PAC系统一起使用时，以下限制适用：%部分支持W内存。只能访问%W的偏移量0-65535通过PCM。
▪ 对于PACSystems，程序名当前始终为LDPROG1。
▪ 如果出现错误NACK，控制程序编号、权限级别和其他背驮状态数据将设置为0。
▪ 如果PCM上运行的应用程序访问VME总线，则该程序使用的VME地址必须更新以符合PACSystems RX7i VME寻址分配。PACSystems RX7iPACSystems RX7i用户手册中描述了VME地址分配VME模块集成指南，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.
