FM350-2程序说明

1、ob82 fc2/ fc3/ fc4/fc5/fc300/db2/udt1/0b1 network1 都要拷贝到原程序中。在 db2.dbw12 中有一个fm350 模块地址的设置。要与s7 硬件配置中fm350 的地址一样硬件配置中地址为i：272-287 q：272-287。db2.dbw12=w#16#110=272. 程序说明ob1 network1 call cishan /调用 fc300 程序块cnt2_app :=w#16#2 /背景数据块号db2 quantity :=mw4 /预装载值，为mw4 赋值，当前为零，也可以用w#16#0 load :=m0.2 /装载计数器值，

2、计数器应用时此点为1 gate0_3 :=m0.0 /打开计数器0-3 通道的软件门gate4_5 :=m0.1 /打开计数器4-5 通道的软件门act_val :=m0.3 /开始读当前计数值的触发位channel :=m0.4 /0 为计数器通道0-3 计数 1 为为计数器通道4-7 计数，应置1 rd_err :=m2.2 /读操作的出错提示wr_err :=m2.1 /写操作的出错提示load_done :=m2.0 /装载计数器操作的状态指示state_oflw:=m2.3 /通道 4 测量值上限溢出状态指示state_uflw:=m2.4 /通道 4 测量值下限溢出状态指示fc30

3、0 程序说明network1 l #cnt2_app /application fill unit t #cnt2_db /open counter data block opn db #cnt2_db call cnt2_ctr /control the fm 350-2 调用 fc2 db_no:=#cnt2_db a dbx 36.7 /fm 350-2 parameters assigned? jcn end /no, process no application a dbx 38.4 /lower limit exceeded? = #state_uflw a dbx 39.4 /u

4、pper limit exceeded? = #state_oflw a #gate0_3 /start the fill unit? = dbx 23.0 /yes, sw_gate0 open = dbx 23.1 /yes, sw_gate1 open = dbx 23.2 /yes, sw_gate2 open = dbx 23.3 /yes, sw_gate3 open a #gate0_3 /start the fill unit? a dbx 43.0 /yes, ctrl_dq0 = stat_gate0 = dbx 21.0 /and trigger fill valve a

5、 #gate0_3 /start the fill unit? an dbx 42.0 /yes, invert stat_dq0 = dbx 21.1 /and trigger motor for transport = dbx 22.1 /with ctrl_dq1 and set_dq1 a #gate4_5 /start the frequency measurement? = dbx 23.4 /yes, sw_gate4 open = dbx 23.5 /yes, sw_gate5 open / = dbx 23.6 /yes, sw_gate6 open 想要使用通道6将前面注释

6、符去掉/ = dbx 23.7 /yes, sw_gate7 open 想要使用通道7将前面注释符去掉network2 set /set br for error evaluation save opn db #cnt2_db /open counter data block a dbx 1.0 /load comparator in progress? jc wrdo /yes a dbx 42.1 /new loading only during transport jcn wren a #load /load new quantity? fp m 10.0 /positive edge

7、to #load 注意不能和程序其它地方应用冲突jcn wren /no l #quantity /quantity in counter data block t dbd 116 l 42 /job_no 30 for t dbb 0 /load comparator count channel 0 wrdo: call cnt2_wr /load counter and comparator for fm 350-2 db_no :=#cnt2_db ret_val:=mw6 /注意不能和程序其它地方应用冲突wren: an br /error: job_no unknown, retva

8、l_wr with error or data error = #wr_err an #load /create write job ended r dbx 1.1 /deleted when loading triggered a dbx 1.1 = #load_done network 3 set /set br for error evaluation save opn db #cnt2_db /open counter data block a dbx 3.0 /read actual values in progress? jc rddo /yes an #act_val /reading actual values? jc rden /no l 100 /job_no 100 for count channel 0 to 3 an #channel /for count channel 4 to 7? jc job l 101 /job_no 101 for count channel 4 to 7 job: t dbb 2 /load comparator count channel 0 rddo: call cnt2_rd /load counter and compara
