Diagnostics
G
WORD
Contains the diagnostic messages (low
byte):
Diagnostics messages:
– Bit 0 to Bit 2: reserved
– Bit 3:
0 = ok
1 = "parameter error":
The set parameter values are not
supported.
– Bit 4:
0 = ok
1 = "hardware failure":
The module has to be replaced, e.g.
EEPROM or UART may be defect.
– Bit 5:
0 = ok
1 = "handshake error":
The DTE connected to the module does
not answer a XOFF or RTS handshake.
This may cause a overflow in the internal
receive-buffer.

– Bit 6:
0 = ok
1 = "frame error":
The module has to be parameterized to be
adapted to the data structure of the
connected DTE. A "frame error" occurs if
the parameterization (number of data bits,
stop bits, parity) is not correct.
– Bit 7:
0 = ok
1 = "buffer overflow":
Overflow in the RX-buffer.
– High byte: reserved

0 = "1byte ctrl/status header": The diag-
nostic data are not part of the process input
data, 7 bytes of user data are available.
1 = "2byte ctrl/status header": The diag-
nostic data are part of the process input
data, 6 bytes of user data are available.
