Project description

Description

通过调用相应接口可对系统内变量进行信息查询、设置值等操作

How to Use

sample:

::

from VarOperHelper import operHelper
from VarOperHelper.datamodel import StatisticsType

varhelper=operHelper.VarOper('127.0.0.1',8899)
varnames = ['CGS_CMD_AUTO', 'CGS_CMD_TOTAL', 'CGS_CMD_SCADA', 'CGS_CMD_MOBILE', 'CGS_PCR', 'CGS_CRR', 'CGS_CQE','xxxx']

#返回VarValue对象列表
lstvarvalues=varhelper.getVarValue(varnames)
if lstvarvalues is not None:
   print('打印VarValue信息如下:')
   for item in lstvarvalues:
       print('Name:{0} IsOK:{1} RawValue:{2} Value:{3} Date:{4}'.format(item.Name,item.IsOk,item.RawValue,item.Value,item.Date))

#返回VarSummary对象列表
lstvarSummary = varhelper.getVarSummary(varclass='IO,MEM',rwmode='rw')
if lstvarSummary is not None:
   print('打印VarSummary信息如下:')
   for item in lstvarSummary:
       print('Name:{0} Desc:{1} Type:{2} RW:{3} Unit:{4} Quality:{5} TagName:{6}'.format(item.Name, item.Desc, item.Type, item.RW,

# 返回VarDetail对象列表(BasicInfo为VarSummary类型  ValueInfo为VarValue类型)
lstvarDetails = varhelper.getVarDetail(varnames)
if lstvarDetails is not None:
    print('打印VarDetail信息如下:')
    for item in lstvarDetails:
        print('Name:{0} IsOK:{1} Desc:{2} Value:{3}'.format(item.Name, item.IsOk, item.BasicInfo.Desc, item.ValueInfo.Value)                                                                  item.Unit,item.Quality,item.TagName))

# 返回VarValue对象列表
lstVarValueBuffer = varhelper.getValueBuffer('CGS_CMD_TOTAL', 0, 5)
if lstVarValueBuffer is not None:
    print('打印ValueBuffer信息如下:数据共:', len(lstVarValueBuffer), '条')
    for item in lstVarValueBuffer:
        print('Name:{0} IsOK:{1} RawValue:{2} Value:{3} Date:{4}'.format(item.Name, item.IsOk, item.RawValue, item.Value,item.Date))

# 返回 VarStatisticsResult类型对象
varstaticresult = varhelper.getValueStatistics('CGS_CMD_TOTAL', StatisticsType.RawValueAvg)
if varstaticresult is not None:
    print('打印ValueStatistics信息如下:')
    print(varstaticresult.IsOk, varstaticresult.Result)

 varnames = [{'Name': 'CGS_CMD_AUTO', 'Value': '20'}, {'Name': 'CGS_CMD_TOTAL', 'Value': '20'},
        {'Name': 'CGS_CMD_SCADA', 'Value': '20'}, {'Name': 'CGS_PCR', 'Value': '20'}]
 # 返回 SetVarValue对象列表
 lstRet = varhelper.setVarValue(varnames)
 if lstRet is not None:
    print('打印SetVarValue信息如下: 共:', len(lstRet), '条\n')
    for x in lstRet:
        print(x.Name, x.IsOk)

The above sample output:

::

  打印VarValue信息如下:
  Name:CGS_CMD_AUTO IsOK:True RawValue:0.0 Value:0.0 Date:2018-09-03 13:17:14
  Name:CGS_CQE IsOK:True RawValue:0.0 Value:0.0 Date:2018-09-03 09:02:36
  Name:xxxx IsOK:False RawValue:None Value:None Date:0001-01-01 00:00:00

  打印VarSummary信息如下:
  Name:CGS_YEWEI_2 Desc:粗格栅后液位 Type:e_IO_float RW:e_RW Unit:m Quality:e_Bad TagName:Sample.Device1.CGS_YEWEI_2
  Name:CGS_CMD_TOTAL Desc:当月发出的控制指令总数量 Type:e_IO_Int RW:e_RW Unit:条 Quality:e_Bad TagName:Sample.Device1.CGS_CMD_TOTAL
  Name:CGS_CMD_AUTO Desc:当月由程序自动发出的控制指令数量 Type:e_IO_Int RW:e_RW Unit:条 Quality:e_Bad TagName:Sample.Device1.CGS_CMD_AUTO
