1、线圈1起始地址为0数量为8软件设置如下(功能码1) 2、线圈2起始地址为8数量为8软件设置如下(功能码1) 3、离散输入起始地址为0数量为8软件设置如下(功能码2) 使用EPICS Modbus模块对以上modbus设备进行读写过程如下
使用makeBaseApp.pl构建IOC程序框架并且在configure/RELEASE中指定base所在路径以及所需要的支持模块modbus路径。在程序的src路径下Makefile中指定要添加的数据块定义文件和库文件。
在程序的Db目录下编写如下模板文件
1 bo_bit.template用于写modbus设备的单线圈
record(bo,$(P)$(R)) {field(DTYP,asynUInt32Digital)field(OUT,asynMask($(PORT) $(OFFSET) 0x1))field(ZNAM,$(ZNAM))field(ONAM,$(ONAM))
}
2bi_bit.template用于读modbus设备的线圈状态或者离散输入状态
record(bi,$(P)$(R)) {field(DTYP,asynUInt32Digital)field(INP,asynMask($(PORT) $(OFFSET) 0x1))field(SCAN,$(SCAN))field(ZNAM,$(ZNAM))field(ONAM,$(ONAM))field(ZSV,$(ZSV))field(OSV,$(OSV))
}
3wfo_bit.template用于一次写modbus设备的多个线圈
record(waveform,$(P)$(R)) {field(DTYP,asynInt32ArrayOut)field(INP,asyn($(PORT) $(OFFSET0))MODBUS_DATA)field(FTVL,ULONG)field(NELM,$(NELM))
}
4 wfi_bit.template用于读取modbus设备多个线圈状态或这多个离散输入状态。
record(waveform,$(P)$(R)) {field(DTYP,asynInt32ArrayIn)field(INP,asyn($(PORT) $(OFFSET0))MODBUS_DATA)field(SCAN,$(SCAN))field(FTVL,ULONG)field(NELM,$(NELM))
}
将以上模板文件添加到相同路径下Makefile文件中
...

DB bi_bit.template
DB wfo_bit.template
DB wfi_bit.template
...
