(3) Issuing operation commands to a sensor amplifier
Message communication issues operation commands such as zero shift or reset to
the sensor amplifiers connected to the DL-EP1.
Service code 4BH is used.
The following settings are required to use this object.
• Service Code
• Class ID
• Instance ID
• Attribute ID
Before executing an operation command, confirm that the sensor amplifier
is ready to execute operation commands. For the confirmation method,
refer to “SK-1000 Series Instruction Manual”. After executing an operation
command, confirm the successful completion of the command.
• Attribute IDs supported by the instance service 4BH (operation command)
The contents of processing performed by the instance service 4BH (operation
command) depend on the attribute ID to be selected.
The table below details the attribute IDs that can be selected.
Attribute ID Name Description
0301H
(769)
Zero shift execution
request
Executes zero shift. Turning off the power to the sensor
amplifier after executing zero shift restores the state
that existed before the zero shift function was used. To
retain the shifted state after turning off the power, turn
on the zero shift value memory function.
0302H
(770)
Zero shift reset execution
request
Resets the zero shift value.
0303H
(771)
Reset request Executes resetting.
0305H
(773)
Initial reset request
Initializes all settings, except for sensor amplifier
system parameters. Once an initial reset request is
executed, all parameters are stored into the nonvolatile
memory (EEPROM) in approximately three seconds.
When completed, the setting/status command
parameter "EEPROM write result" flips to "successfully
completed (1)". After the completion, "EEPROM write
result" of the attributes for SK-1000 Series changes to
Normal termination (1).
0306H
(774)
System parameter set
request
Changes the system parameters (the polarity of the
judgment and alarm outputs and the analog output
setting) to the values written in "System parameter
settings" of the attributes for SK-1000 Series.
To set the system parameters, confirm that the change
is proper according to the connected devices and
wiring.
A wrong change may damage the sensor amplifier or
the connected equipment.
