The MODIDN? query returns the module's model name and serial number.
Parameters
None. The response consists of the module's model number, serial number, and version number,
separated by commas.
Notes
The serial number may also be found by removing the module from the mainframe and viewing the
serial number information on the side of the module.
Examples
“MODIDN?” -response: “3916374,03740001,v1.00”, means the module was a model 3916374,
serial number 03740001, firmware version 1.00.
The MODPUD command allows the service technician to enter protected user data. This data is
normally changed only at the factory, and therefore the MODPUD command is not needed by the
user.
The MODPUD? query returns protected user data from a module. This data is entered by factory
personnel when the module is calibrated.
Parameters
None. The response consists of serial number, hardware version, option information, calibration
date, and initials of the calibrating technician. The response is in the form of <arbitrary block data>
with the header, #221, indicating twenty-one characters.
Notes
The serial number may also be found by removing the module from the mainframe and viewing the
serial number information on the side of the module.
Examples
“MODPUD?” -response: #221037200020011120498grb
The RADix command allows the programmer to select the radix type for status, condition, and
event query response data. Decimal, binary, hexadecimal, and octal are allowed.
Parameters
Character program data is expected, as shown above.
Notes
DECimal is the default type. Only the first three letters of the words decimal, hexadecimal, binary, or
octal are required.
When the RADIX is selected, all status, condition, and event queries will return values in the new
radix.
In cases where the radix is not DECimal, the flexible numeric type <nrf value> (as shown in the
Command Reference diagrams) will be replaced by HEX, BIN, or OCT representation.
All of the above radixes may be used to enter program data at any time, without the need for
issuing the RADix command. The proper prefix must also be used with Hex (#H), binary (#B), or
octal (#Q).
This command may be useful for setting up status reporting blocks. The bit-wise status
representation may be more easily read in BIN, HEX, or OCT.
Examples
“RAD dec” -action: the decimal radix is selected.
"rad hex; *ESR?" -action: the hexadecimal radix is selected; -response: #H80, means power-on
was detected.
