4.3.6 FIXPRM_RD (Read Fixed Parameter)
The current value of the fixed parameter that is specified in the OW5C setting parameter
(Fixed Parameter Number) is reported in the IL56 monitor parameter (Fixed Parameter
Monitor).
Execution and Operating Procedures
1. Make sure that the following condition is met.
* This subcommand cannot be executed until the execution of other motion subcommands is completed.
2. Set the OW5C setting parameter (Fixed Parameter Number).
3. Set the OW0A setting parameter (Motion Subcommands) to 5 to execute the FIX-
PRM_RD motion subcommand.
The current value of the specified fixed parameter is read, and the code is stored in the monitor
parameter.
The IW0A monitor parameter (Motion Subcommand Response Code) is 5 during execution of
this command.
During command processing, bit 0 in the IW0B monitor parameter will change to 1 (Process-
ing). When processing is completed, this bit will change to 0 (Completed).
4. Set OW0A to 0 to execute the NOP motion subcommand.
This concludes the read fixed parameter operation.
