5.3.33 “MWF” Command
The ‘MWF’ command lets users write a desired “field” item in a defined
EEPROM cell.
The correct form format for this command is as follows:
MWF:cell_num:cell_content\r
where:
 cell_num is the EEPROM cell number;
 cell_content is the ASCII content to be written to the EEPROM cell cell_num.
The on-board EEPROM memory - used to store module information as
calibration parameters, identification, thresholds and divided in two sections, “field”
and “value” – has 512 cells, so that cell_num is limited between 0 and 511; writing
operations containing cell values exceeding these limits obtain a non-acknowledgment
reply ‘#NAK\r’.
This “field” section of the EEPROM is used to store descriptive items as
interlocks identification names (cells 50 through 53).
Replies from the power supply are in the form ‘#AK\r’, or ‘#NAK\r’; this nonacknowledgment reply is generated when:




the A3660BS module is in LOCAL mode;
the cell number cell_num is out-of-range (negative or greater than 511);
cell_num or cell_content are empty strings;
the selected cell is password protected and password protection is not
unlocked (see ‘PASSWORD\r’ command for further details).
Examples:
MWF example with the module in LOCAL mode:
MWF:52:INTERLOCK_A\r
#NAK\r
MWF correct example (after password is unlocked):
MWF:52:INTERLOCK_A\r
#AK\r
