RFID commands

Note
Notation for the commands
For reasons of compatibility the obsolete terms "MOBY", "MDS" and "SLG" have been
retained in commands and the descriptions of the commands. These terms are stored in the
program and in the data blocks and therefore continue to be used in this manual.
Note
This section provides a description of all commands that can by processed by FB 45. The
commands that can actually be processed by the communications module you are using, are
described in section Brief description of the hardware (Page 81).
Before you can start an RFID command with command_start, you need to define the
command. UDT 20 (commentary in English), UDT 21 (commentary in German) or UDT 24
(Spanish commentary) is available for the simple definition of a command.
FB 45 for MOBY U, MOBY D, RF200, RF300
Function Manual, 07/2012, J31069-D0166-U001-A4-7618
No significance. This variable is always FALSE.
The CM is currently running a command repetition. The bit is set as a response to the control
variable repeat_command. After an init_run, command_rep_active is first reset by FB 45 and
then set again after a delay because FB 45 first transfers the RFID commands to the CM.
The number of transponders currently in the transmission window is displayed.
If there are more than 15 transponders in the field, the number_MDS display remains set to
0F hex.
The display is only available and valid if the reader being used has this function (MOBY U,
MOBY D and RF300).
This error was signaled by the CM or reader. The error is usually displayed by the ERR LED
on the CM and/or reader (see Section "Error messages and troubleshooting (Page 47)").
Error message from FB 45 (see section "Error messages and troubleshooting (Page 47)")
The transmission path between FB 45 and the CM reports an error. This is usually a
PROFIBUS/PROFINET error. (see section "Error messages and troubleshooting (Page 47)").
This error is signaled by system functions SFC 58/59.
Display of the communications module firmware version. The value entered here is updated
each time the CM starts up. It is ASCII-coded.
