End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been read. Re-
fer to
Section 4-1-2 End Codes for a description of the other possible end codes
and their meanings.
4-2-17 EEPROM Write: WE
This command is used to write the parameters stored in ROM into EEPROM so
that they will be preserved if the power is interrupted. This function is used to
preserve values when they are initially input, and to permanently store any
changes made to the RAM-held parameters. Remember, all commands except
for this one affect only the parameters held in RAM; when power is applied to the
E5ZD, the values in the EEPROM are returned to RAM.
The EEPROM has a limited overwrite life of approximately 10,000 times; do not
use the EEPROM Write command needlessly.
Writing to EEPROM requires time, and the response to EEPROM Write can be
delayed by as much as 3.5 seconds for Fuzzy-logic Controllers and as much as
2.3 seconds for other Controllers.
Command Format The format for this command is as shown below. The unit number must be speci-
fied.
@ 0 Unit W E A A 0 0 0 0 0 7 CR

Terminator Always A A.
Always 0007.

Command Examples The following command is used to write the parameter of Unit 0 into the EE-
PROM.

Response Format The response returned for this command is shown below. This response
assumes that the header code in the command block was transmitted and read
normally. If the header code in the command block was not recognizable, a
header code of IC will be returned without an end code (see
Section 4-1-2 End
Codes for the IC header code response format).
@ 0 Unit W E End code CR

End Codes If an end code of 00 was returned in the response, the command was executed
normally. If the end code is not 00, the desired data will not have been written.
