|MB-Gateway Revision History|
Description of Problems / Additions / Changes
|1.0.684||5.0.53||23 May 2018||
Added ability to disable using port 502 for Modbus/TCP and specify a range of alternate port numbers to use for Modbus/TCP.
Configuring this option requires the use of
NetEdit v3.16 or later.
|1.0.681||5.0.53||3 Nov 2017||
When an attempt to access an address
that is out of range, the MB-Gateway will now correctly returning the error
code for Illegal Data Address (2) instead of the error code for Parity Error
|1.0.679||5.0.53||18 Sept 2015||
Added ability to read the error count
for each of the Automatic Read operations.
|1.0.643||5.0.53||25 June 2015||
Added ability to log TCP and/or RTU requests the MB-Gateway is processing using the free SMTPViewer utility (download and install it in the \HAPTools folder).
For a table entry, a CRC error will
flash the error light and set the Last table error to:
MODBUS_ERROR_MEMORY_PARITY_ERROR. For a direct request from a Modbus TCP
server, a Modbus RTU parity error will return the error
MODBUS_ERROR_MEMORY_PARITY_ERROR to the Modbus TCP server.
|1.0.613||5.0.53||02 March 2015||
Large broadcast packets - where the
sender has split the data into multiple packets because there was too much
data for a single packet - that required reassembly to make a complete
packet, would cause the MB-Gateway to crash. Since the MB-Gateway does not
use any broadcast packet that is this large, this problem was fixed by not
allowing the TCP/IP stack in the MB-Gateway to reassemble broadcast packets
that have been split.
|1.0.601||5.0.53||04 May 2011||
NetEdit3 v3.8 or later for
