Type Description
Detailed Number of transmission timeout errors.
Detailed Number of character parity errors detected.
Detailed Number of character overrun errors
detected.
Detailed Number of character overrun errors
detected.
1 = Reset counters (by entering 1 the
diagnostic counters are reset)
Function
Counts all incoming non-erroneous characters.
This counter operates regardless of if the serial
driver is set to detect a whole protocol link frame or
just separate characters.
Counts all protocol specific non-erroneous frames
received. Protocol-specific frames can be based
on timing (for example, Modbus RTU) or on
special start and stop characters (for example,
Modbus ASCII).
Counts all protocol-specific erroneous frames
received. If the driver detects an error while
receiving a frame, the frame is automatically
discarded. This also means that the protocol in
question will never receive a faulty frame from the
driver. When this counter is increased, one of the
detailed error counters is also incremented.
Counts all protocol-specific frames transmitted
from the COM channel.
Function
In RS-232 handshake mode, characters are to be
received as long as Carrier Detect (CD) signal is
active. This counter is incremented if the CD signal
is lost during reception.
Counts transmission collisions. Used in RS-485
mode by some protocols where transmissions
could collide. For example, DNP3 unsolicited
mode.
In RS-232 handshake mode the Clear To Send
(CTS) signal is not received as reply to this device
Request To Send (RTS) signal.
