Appendix 3 Details of Remote Buffer Memory
(26)Parameter area initialization command
This command is used to set parameters in remote buffer memory areas and non-volatile memory to a default
value.
In the event of a non-volatile memory data error (parameter) (error code: 0130H), using this command makes it
possible to recover the module.
(a) Behavior of parameter area initialization
Setting Parameter area initialization command (address:1002H) to Commanded (1) sets the parameters in the
non-volatile memory back to default values.
(b) Default value
The default value is Not commanded (0).
(c) Remote buffer memory address
The remote buffer memory address of this area is as follows:
An execution of Parameter area initialization command (address: 1002H) does not clear the following remote input signals
and remote registers:
• Warning flag (RX7)
• Error flag (RXA)
• Alert output signal (RX18, RX28)
• Input signal error detection signal (RX1C, RX2C)
In addition, Remote READY (RXB) does not turn on.
After the execution of Parameter area initialization command (address: 1002H), turning off and on the module power supply
enables the module to operate normally.
