APPENDIX 1. APPLICATION, SETTING AND CHANGE OF BASIC PARAMETERS
A1.2 Setting and Change of
Basic Parameters
This section describes the procedure taken to set and
change the parameters for each block. Obtaining access
to each parameter differs depending on the configura-
tion system used. For details, refer to the instruction
manual for each configuration system.
Access the block mode (MODE_BLK) of each block.
Set the MODE_BLK
(*Note 1)
to Auto, Man or O/S
(*Note 2)
according to the Write Mode of the parameter to be set or
changed.
FA0101.EPS
Access the parameter to be set or changed.
Make setting or change in accordance with each parameter.
Set the Target of block mode (MODE_BLK) back to Auto
(*Note 2) .
IMPORTANT
Do not turn the power OFF immediately after
parameter setting. When the parameters are
saved to the EEPROM, the redundant process-
ing is executed for the improvement of reliability.
If the power is turned OFF within 60 seconds
after setting of parameters, changed parameters
are not saved and may return to their original
values.
When the consecutive parameter setting to the
multiple parameters is not executed via the
acyclic data exchange, the time inverval between
each parameter setting must not be within 2
seconds.
Changed parameters may not be written to the
device.
Note 1:Block mode consists of the following four modes that are
controlled by the universal parameter that displays the
operating condition of each block.
- Target: Sets the operating condition of the block.
- Actual: Indicates the current operating condition.
- Permit: Indicates the operating condition that the block is
allowed to take.
- Normal: Indicates the operating condition that the block will
usually take.
Note 2: The followings are the operating conditions which the
individual blocks will take.
