Requesting the Active Program Name: SD1=02
To request the active program name, send a message with CMD=61 (hex)
and SD1=02. For example:
CMD SD1 SD2 SD3 TNS TNS
DLE STX 61 02 00 00 04 01 DLE ETX BCC
the application software responds with:
CMD SD1 SD2 SD3 TNS TNS DATA
DLE STX 61 02 00 00 00 03 PROGRAM1 NULL DLE ETX BCC
ASCII
The active program is an ASCII string of 8 characters (maximum) ending
with a NULL. If there is no active program, a NULL is returned.
Requesting the Block Number: SD1=03
To request the block number, or the last N word that was executed, send a
message with CMD=61 (hex) and SD1=03. For example:
CMD SD1 SD2 SD3 TNS TNS
DLE STX 61 03 00 00 01 02 DLE ETX BCC
the application software responds with:
CMD SD1 SD2 SD3 TNS TNS DATA
DLE STX 61 03 00 00 02 01 N12345 NULL DLE ETX BCC
ASCII
The block number is an ASCII string of 5 characters (maximum, with
leading zeros suppressed) ending with a NULL. This value is the same
value that’s displayed on the operator panel’s CRT. If no value is displayed,
the software returns a NULL.
Transmit Error Messages to the Teach Pendant: SD1=04
To have the system error messages transmitted to the pendant, send a
message with CMD=61 (hex) and SD1=04. For example:
CMD SD1 SD2 SD3 TNS TNS
DLE STX 61 04 00 00 00 06 DLE ETX BCC
The application software responds by sending error messages as they
occur.
