(74h) Process diagnos-
tics data G BYTE Contains the diagnostic information: The
diagnostic data are part of the process input
data, if ACTIVE MODE = 1 or "2bytes
ctrl/status header" is set.
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.

(74h) Process diagnos-
tics data G BYTE – 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.
– Bit 8 to Bit 15: reserved

(75h) RX data G ARRAY OF
BYTE Defines the receive-data (0...7).
