5.5.1 Operation flow of the program run

■ Digital controller: This section explains operation process of the program run using TTM-200. To

perform a program run, the SET 20, SET 21 and SET 22 parameters must be set.

■ The setting content is as follows:

Set a parameter desired to change with setting value in the SET 20 bank setting for each step.
For the setting, select a parameter requiring to be switched during a program run from SETs 1 to
17
.

For details of the bank setting, see operation explanation - bank function (P5-28 to 30).

The SET 21 program function setting sets a program run method. Also, the SET 22 program
setting sets a program run pattern. Perform the settings according to this manual.

Note No program is used in “constant value run mode” and “program run mode.” In “constant value

run mode,” the SET 22 program is not displayed. A switchover in this mode is made with SET
21 (C/P)
.

The diagram below shows a general process flow of a program run. Settings should be made
along with the flow.

For setting and operation check in Items 2 to 4 below, see “How to set run settings” (P5-4 to 21)
and “How to set each function and description of function” (P5-22 to 46).

1. Planning a program

Plan setting parameters and operating statuses required for control.
• Planning program run patterns
• Planning setting parameters


2. Setting basic settings: Set necessary parameters in SETs 1 to 19.

• “Input setting”: Sensor type, temperature range, etc.
• “Output setting”: Output type, output method, presence of alarm

setting, etc.

• “Presence/absence of event function usage”: DI polarity, etc.
“Presence/absence of timer function usage”: Timer operation method,

time setting, etc.

“Key setting”: Presence/absence of Func key usage, etc.


3. Setting a bank

• Set necessary parameters to the bank by switching SETs 1 to 17 in a

program run.


4. Checking an operation of constant value run mode

• Check the bank settings by manually switching the bank in key

operation or with DI.

Check each of all set banks for planned control condition.

5. Set a program run mode.

Set the SET 21 program function setting and SET 22 program setting in accordance with the program
run chart.


6. Checking an operation of program run mode

• Check operation status of each step by manually switching the step in key operation or with DI.

Caution: Before starting a program run:
Check program content and control status before starting an unattended run in order to prevent
accidents during the program run.
