Chapter 5. FUNCTIONS

RUN

The RUN mode indicates that the program is run sequentially.

MV output and events operate during PID control, ON-OFF control and other types of control. In the program RUN mode, program operation progresses according as time elapses. Note, however, that G.SOAK (guarantee soak) wait, like the HOLD mode, halts program operation.

HOLD

The HOLD mode temporarily halts program operation.

Note, however, that, like the RUN mode, MV output and events operate during PID operation, ON-OFF control and other types of control. During constant value control the HOLD mode cannot be invoked.

FAST

The FAST mode is essentially a speeded-up version of the RUN mode. The time factor is selected using variable parameter PA39. MV output and events operate during PID control, ON-OFF control and other types of control. G.SOAK (guarantee soak) settings are ignored.

During constant value control the FAST mode cannot be invoked.

END

The END mode indicates the state of a program that has run its course. When a program stops at the end, MV output and events operate during PID control, ON-OFF control and other types of control.

During constant value control the END mode cannot be invoked.

READY FAST

The READY FAST mode is a combination of the READY and FAST modes.

MV output, SP output and events operate in the same way as in the READY mode. Program numbers and segment numbers cannot be selected. Parameters that can only be changed in the READY mode and memory card operation cannot be performed in this mode.

During constant value control the READY FAST mode cannot be invoked.

AUTO

The AUTO mode performs automatic operation. MV outputs can be used depending on DCP552 control.

MANUAL

The MANUAL mode performs manual operation.

The “”, “”, “” and “” console keys can be used to change communications and MV output.
