循環(huán)時間tC存儲在KD 00,00中，可以是以5毫秒時間步長選擇。如果所選循環(huán)時間為太短，處理器將無法完成任務(wù)分配給它。屆時它將默認(rèn)。如果這種時間不足在幾個周期內(nèi)變得過大，處理器將中止程序執(zhí)行和輸出錯誤（FK2）。使用一些功能塊，例如PID控制器，無錯誤執(zhí)行取決于精確的定時序列確保有更大的時間儲備。循環(huán)時間的正確設(shè)置可以通過以下方式進(jìn)行檢查以下程序：–將用戶程序加載到中央單元。

根據(jù)安裝結(jié)構(gòu)和遙控器類型，可能會有進(jìn)一步的限制模塊。有關(guān)建議的地址，請參閱第A2.2章。
Block copy time, time for copying
the input signals or the out-put
signals from/to the transfer
memory.
It includes:
– Net copy time 0.2 ms
– 2 interface interrupts of
0.1 ms each
– If expanded by remote modules, waiting time for access
authorization:
binary mod. only: 1.1 ms,
also analog mod.: 2.7 ms
(2 x interrogation time on
the CS31 system bus)This equation assumes that the processor always gets
access in the most unfavourable moment.
The cycle time tC is stored in KD 00,00 and can be
selected in 5 ms time steps. If the selected cycle time is
too short, the processor will not be able to fulfill the tasks
assigned to it. It will come in default then.If this lack of time is getting too large over several cycles,
the processor will abort the program execution and output
an error (FK2).
Using some function blocks, such as the PID controller,
the error-free execution depends on an exact timing
sequence. Make sure that there is a larger time reserve.
The correct setting of the cycle time can be checked by
the following procedure:
– Loading the user program into the central unit.
– If the operating mode has been switched over from
stand-alone to bus master: Power ON or menu item
”Enable PLC mode” in the programming software.
– Interrogation of the capacity utilization using the menu
item of ”Display PLC status”.
– Changing the cycle time tC until the capacity utilization
is below 80 %.
Example: Bus master central unit + 1 binary input
module + 1 binary output module
+ 2 analog input modules Without regard to the address ranges, the following modules can be connected to a CS31 system bus:
– max. 1 bus master
– max. 31 remote modules / slaves
Further restrictions result from the address range of the central units 07 KR 91 / 07 KT 92/93:
– max. 12 analog input modules
– max. 12 analog output modules
– max. 31 binary input modules
– max. 31 binary output modules
There may be further restrictions according to the structure of the installation and the type of remote
modules. For the recommended addresses, see chapter A2.2.
