Chapter 6 Applied Instructions 6-175 Data Setting Device number Function Description type range MV MAX _ REAL Maximum output value Range of single- precision floating- point numbers Suppose MV MAX is set _ to 1,000. When the MV is larger than 1,000, 1,000 is output. The value in MV MAX _ should be larger than that in MV MIN. _ Otherwise, the maximum MV and the minimum MV will be reversed. MV MIN _ REAL Minimum output value Range of single- precision floating- point numbers Suppose MV MIN is set _ to -1,000. When the MV is less than -1,000, -1,000 is output. MOUT REAL Manual output value It is used with the PID MAN _ mode. Users set the MV directly.
I MV (It _ occupies six consecutive 32-Bit devices.) REAL I MV _ The accumulated integral value is temporarily stored in it. Range of single- precision floating- point numbers The accumulated integral value is only for reference. It still can be cleared or modified according to users’ need. When the MV is larger than the MV MAX, _ or when the MV is less than MV MIN, the _ accumulated integral value in I MV is _ unchanged. I MV+1 _ The previous PV is temporarily stored in it. The previous PV is only for reference. It still can be modified according to users’ need. I MV+2 _ ~ I MV+5 _ For system use only
