组测试顺序
每个MV都有几个参数用于测试组制定整体组测试计划。这些参数包括：
•STMVORDER - 相对顺序参数
•STMVSTEPS - 要求的单个迭代阶跃数
•STMVDUR – 需求的主阶跃长度
•STMVSRV - 测试服务开关
根据这一组参数，智能向导应用可以确定阶跃测试顺序。当前的MV(STGCURRMV)值和下一个MV(STGNEXTMV)值对用户都是可用的。如果应用运行为开环状态（ONSTS= OFF），则当前MV值为0，下一个MV值将显示MV阶跃后的值。
注：智能向导应用锁定当前MV（若应用是开环的，则锁定下一个MV）。当MV被锁定时，用户将无法通过操作STMVORDER和STMVSTEPS改变当前MV值。例如：若应用被关闭，且STGCURRMV=0，STGNEXTMV=2。如果工程师不希望重新开启应用测试MV2，那么他们就应该设置自己的习惯，并且至少关闭测试服务开关MV2一个周期。这将导致测试计划中另一个MV被锁定。

Group testing order
Each manipulated variable has several parameters that are used by the test group to devise the overall group test plan. These parameters include:
•STMVORDER – Relative order parameter
•STMVSTEPS – Number of steps requested for a single iteration
•STMVDUR – Requested length of the major step
•STMVSRV – Test service switch
From this set of parameters, the SmartStep application determines a step test order. The values of both the current MV (STGCURRMV) and the next MV (STGNEXTMV) are available to the user. If the application is running open loop (ONSTS = OFF), then the current MV will be zero and the next MV will show the next MV to be stepped.
Note: A SmartStep application locks the current MV (or, if the application is open loop, the next MV). The user will be unable to change the current MV by manipulating STMVORDER or STMVSTEPS when the MV is locked. STMVSRV can be used to unlock an MV. For example: the application is turned OFF, and the STGCURRMV=0, and the STGNEXTMV=2. If the engineer does not wish to turn the application back on and test MV2, then they should set the order to their preference, and turn off the test service switch for MV number two for at least one cycle. This will cause another MV to be locked into the test plan.
