使用启用/禁用计数过程
用户程序中的内部变量A 63,14：–A 63,14=0：内部变量A 63,13=1启用计数过程，而A 63,13=0禁用它–A 63,14=1：
端子06处的信号1（也指定为E62,01）启用计数程序，而信号0禁用它。A 63,13无效。
注：停滞时间可能为0…1.5毫秒。
在用户程序中设置计数器：–内部单词变量中包含的值
秋冬06,15
–使用内部变量A 63,15=1。
注：如果存在内部变量A 63,15=1
在几个处理周期中，处理器设置
在每种情况下，程序结束时的计数器。
在处理周期的剩余时间内计数器对端子05处的脉冲进行计数。
计数器内容可以通过内部读取变量EW 06,15。过零信息（信号从0变为1
计数器内容从-1变为0时）：
–始终通过内部变量E 63,13
–在40号航站楼（也称为A62,00）仅当设置内部变量A 63,14=1时。
注：反应时间可能为0…1.5毫秒
直接控制用户输出A 62,00程序被A 63,14=1禁用。
当计数器已设置。
将二进制信号快速输入用户程序<0.02 ms的延迟：
–端子05（也称为E 62,00）：内部变量E 63,14
–端子06（也称为E 62,01）：
内部变量E 63,15配置示例任务：
–每单位货物必须填充180件包装。
–每个填充件生成一个脉冲。
–当包装满时，计数器立即为下一次填充操作做好准备。
–发送填充操作的启用信号包装机。
–计数操作的结束必须立即向包装机发出信号。
接线
–将计数脉冲的信号线连接至端子05。
–连接信号线以启用计数操作至端子06。
–连接信号线以实现计数器连接到端子40。
配置步骤：PLC程序
1） 激活端子06和40–使用操作数A 63,14。IL（指令列表）：! 00,01肯尼亚=A 63,14（K 00,01=1）
2） 计数器的预设起始值起始值（AW 06,15）设置为–180。计数器将从开始计数正方向–180。从-1到将向0发送信号。IL（指令列表）：! 01,00千瓦=AW 06,15（KW 01,00=–180）3） 在计数器中采用起始值每次计数操作后，起始值为立即通过“过零”信号（E 63,13）。操作数A为此，必须设置63,15=1。在程序中start，启动值加载到计数器中一次通过初始化标志M 255,15（程序启动后，M 255,15的值为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).
