8) _ATxx_ERR_CODE (Error code)
It indicates error code in case an error occurs during the auto-
tuning of ‘xx’th loop. The flag, as
a dedicated monitor, is updated although a user directly enters it. For more information about
error code, refer to 15.5.
9) _ATxx_K_p, _ATxx_T_i, _ATxx_T_d (AT result proportional coefficient, integral time, differential
time)
The area indicates proportional coefficient, integral time and differential time calculated after
the auto-tuning of
‘xx’ th loop is normally completed. The flag, as a dedicated monitoring,
updated although a user directly enters it.
10) _ATxx_PV (PV)
It is the area to receive PV of
‘xx’ th auto-tuning loop. PV is the present status of a system to
control and in case of PID control, the entry from a sensor is saved into U device through input
devices such as A/D input module and it moves the value to _ATxx_PV by using commands
such as MOV every scanning, executing auto-tuning.
11) _ATxx_MV (Auto-tuning MV)
It is the area to output MV of
‘xx’ th auto-tuning loop. Every auto-tuning cycle, it saves XGB
auto-tuning and it delivers the value in the area by using commands like MOV in a program and
operates a drive every scanning.
