Function
When turning on the setting value write command X100, the parameters,
which are set in this program example, are as follows.
• CH2 Unused channel setting
• CH1 Input range
• CH1 Alert 1 mode setting
• CH1 Alert set value 1
• CH1 Set value setting
• CH1 Upper setting limiter
• CH1 Lower setting limiter
When program control is used, turn on X100 after turning on X112
(program control pattern data setting command).
*1: PID constants of zone 1 and zone 2 that are used for program control are set.
By turning on X11, the auto tuning is executed after switching into normal control
mode.
Then PID constant of zone is set when the auto tuning ends.
Description
Sets the parameter to execute normal control and program control
using CH 1 and writes into FeRAM.
Reads PID constant set by auto tuning from FeRAM.
Executes auto tuning for the specified set value.
Operates only in the normal control mode.
Clears(0) error codes.
Switches into the setting mode by turning off then on.
Switches into the normal control mode by turning off then on.
Needs to set parameters for normal control before switching.
Switches into the program control mode by turning off then on.
Needs to set parameters for program control before switching.
Switches into the manual control mode 2 by turning off then on.
After the switching, the operation is performed by the values of
manual output settings (X20 to X2F).
Switches into the cascade control mode by turning off then on.
Needs to set parameters for cascade control before switching.
Executes auto tuning for program control.
Sets the pattern data for executing program control.
Sets parameters for executing cascade control.
Specifies the manipulated value when manual control mode 2 is
operated.
Outputs error codes as BCD value.
Outputs measured value as BCD value.
Outputs when reading from FeRAM has failed.
Outputs when writing into FeRAM has failed.
Stores error codes that are read out when the error has occurred.
Stores measured values that are read out.
: 1 (Unused. However, set "used"
when used for cascade control. In
this case, parameter is set to the
same as CH1.)
: 0 (K: -200 to 1372 )
: 1 (UprLmt Input Alert)
: 1800 (180 )
: 800 (80 )
: 2000 (200 )
: 0 (0 )
