使用啟用/禁用計數過程
用戶程序中的內部變量A 63,14：–A 63,14=0：內部變量A 63,13=1啟用計數過程，而A 63,13=0禁用它–A 63,14=1：
端子06處的信號1（也指定為E62,01）啟用計數程序，而信號0禁用它。A 63,13無效。
注：停滯時間可能為0…1.5毫秒。
在用戶程序中設置計數器：–內部單詞變量中包含的值
秋冬06,15
–使用內部變量A 63,15=1。
注：如果存在內部變量A 63,15=1
在幾個處理周期中，處理器設置
在每種情況下，程序結束時的計數器。
在處理周期的剩余時間內計數器對端子05處的脈沖進行計數。
計數器內容可以通過內部讀取變量EW 06,15。過零信息（信號從0變為1
計數器內容從-1變為0時）：
–始終通過內部變量E 63,13
–在40號航站樓（也稱為A62,00）僅當設置內部變量A 63,14=1時。
注：反應時間可能為0…1.5毫秒
直接控制用戶輸出A 62,00程序被A 63,14=1禁用。
當計數器已設置。
將二進制信號快速輸入用戶程序<0.02 ms的延遲：
–端子05（也稱為E 62,00）：內部變量E 63,14
–端子06（也稱為E 62,01）：
內部變量E 63,15配置示例任務：
–每單位貨物必須填充180件包裝。
–每個填充件生成一個脈沖。
–當包裝滿時，計數器立即為下一次填充操作做好準備。
–發送填充操作的啟用信號包裝機。
–計數操作的結束必須立即向包裝機發出信號。
接線
–將計數脈沖的信號線連接至端子05。
–連接信號線以啟用計數操作至端子06。
–連接信號線以實現計數器連接到端子40。
配置步驟：PLC程序
1） 激活端子06和40–使用操作數A 63,14。IL（指令列表）：! 00,01肯尼亞=A 63,14（K 00,01=1）
2） 計數器的預設起始值起始值（AW 06,15）設置為–180。計數器將從開始計數正方向–180。從-1到將向0發送信號。IL（指令列表）：! 01,00千瓦=AW 06,15（KW 01,00=–180）3） 在計數器中采用起始值每次計數操作后，起始值為立即通過“過零”信號（E 63,13）。操作數A為此，必須設置63,15=1。在程序中start，啟動值加載到計數器中一次通過初始化標志M 255,15（程序啟動后，M 255,15的值為0）。
Enabling/disabling of the counting procedure using
the internal variable A 63,14 in the user program:
– A 63,14 = 0:
The internal variable A 63,13 = 1 enables the
counting procedure, whereas A 63,13 = 0 disables
it.
– A 63,14 = 1:
Signal 1 at terminal 06 (also designated as E
62,01) enables the counting procedure, whereas
signal 0 disables it. A 63,13 is without effect.
Note: The dead time may be 0...1.5 ms.
Setting the counter in the user program:
– to the value contained in the internal word variable
AW 06,15
– using the internal variable A 63,15 = 1.
Note: If the internal variable A 63,15 = 1 is present
during several processing cycles, the processor sets
the counter at the program end in each case.
During the remaining time of the processing cycle, the
counter counts pulses at terminal 05.
The counter content can be read via the internal
variable EW 06,15.
Zero-crossing message (signal changes from 0 to 1
when the counter contents changes from –1 to 0):
– always via the internal variable E 63,13,
– at the terminal 40 (also designated as A 62,00)
only, if the internal variable A 63,14 = 1 is set.
Note: The reaction time may be 0...1.5 ms. The
direct control of the output A 62,00 from the user
program is disabled by A 63,14 = 1.
The zero-crossing message is cancelled when the
counter is set.
Fast input of binary signals into the user program with
a delay of < 0,02 ms:
– Terminal 05 (also designated as E 62,00):
Internal variable E 63,14
– Terminal 06 (also designated as E 62,01):
Internal variable E 63,15 Configuration example
Task:
– 180 pieces each of a unit load have to be filled into
a packing.
– Each filled-in piece generates one pulse.
– When the packing is full, the counter is immediately
prepared for the next filling operation.
– The enabling signal for the filling operation is sent
by the packaging machine.
– The end of the counting operation has to be
signalled to the packaging machine immediately.
Wiring
– Connect the signal line for the counting pulses to
terminal 05.
– Connect the signal line for the enabling of the
counting operation to terminal 06.
– Connect the signal line for ”zero crossing” of the
counter to terminal 40.
Configuration steps: PLC program
1) Activate terminals 06 and 40
– The terminals 06 and 40 are activated using the
operand A 63,14.
IL (instruction list):
! K 00,01
= A 63,14 (with K 00,01 = 1)
2) Preset start value for the counter
The start value (AW 06,15) is set to the value
of –180. The counter will then count starting from
–180 in positive direction. The transition from –1 to
0 will be signalled.
IL (instruction list):
! KW 01,00
= AW 06,15 (with KW 01,00 = –180)
3) Adopt start value into the counter
After each counting operation, the start value is
immediately set again into the counter by means of
the ”zero crossing” signal (E 63,13). Operand A
63,15 = 1 has to be set for this purpose. At program
start, the start value is loaded once into the counter
by means of the initialization flag M 255,15
(M 255,15 has the value of 0 after program start).
