6.7 Procedure to Change Parameters in the SET Mode
If it is desired to change parameters in the SET mode in communication, follow the steps given below:
①
With computer status read command (RC), make sure of the mode.
(1)
If the response is local, select the remote with mode select command.
(2)
If the response is remote, go to
③
.
(3)
If write protected by DIP switch, cancel the DIP setting in the computer.
②
With local/remote select command (SM), switch to the remote.
・
At this point, a message telling you of a switch from local to remote appears on the EL4001 screen.
③
With computer status read command (RC), make sure of the mode.
(1)
If the response is in the SYS mode, select the RUN mode with mode select command (MC).
(2)
If the response is in the SET mode, go to
⑤
.
④
Switch from RUN to SET with mode select command (MC).
・
At this point, the data in the EEPROM is copied to the RAM workarea.
・
The EL4001 display shows the SET mode main menu screen.
⑤
To view the data you want to modify, read the parameters with SET mode data read command (RS).
⑥
With SET mode data write command (WS), change the parameters of interest.
⑦
Repeat steps
⑤
and
⑥
until all changes are made. Then, with mode select command (MC), calculate
the minimum scaling factor for pulse output (SET
→
scaling setup).
・
A response with the minimum scaling factor for pulse output is sent back.
・
With mode select command (MC), you can cancel the modi
fi
cation and return to the RUN mode at
this point.
⑧
With mode select command (MC), switch the scaling setup to the RUN. At this point, the scaling
factor for pulse output you set up is added to the command message.
・
By this process, the contents modi
fi
ed in the RAM workarea is copied to the EEPROM, and the
scaling factor for pulse output is set up.
(1)
If the response is acceptable, a switchover to the RUN mode takes place.
(2)
If the response is unacceptable, the state
⑦
remains unchanged.
・
In this case, with mode select command (MC), you are to cancel or set up the right value again,
and switch from the scaling setup to the RUN once again.
