531X305NTBANG1 GE Controller module Brand new
No CPU fault logged when Ethernet
Interface in fatal blink code
The CPU does not log any Controller or I/O Faults when the Ethernet
Interface has a fatal blink code. The user’s application should monitor the
LAN interface OK status bit to detect loss of module.
EGD I/O has unexpected variability
under heavy load
EGD I/O has intermittent unexpected variability under heavy load. For a
Produced Exchange, EGD samples may occasionally be delayed by as
much as a production period or more.
Clear of large hardware configurations
may cause log event 08/20
A Log event 08/20 may occur when very large hardware configurations
are cleared and transfers are active on other Server connections. This log
event can be safely ignored.
COMMREQ Status Word of 0x54A0
occasionally returned for EGD
commands
Occasional COMMREQ Status Word values of 0x54A0 are returned to
COMMREQs for EGD commands when the previously transferred
command has experienced retries in the network. Executing the
COMMREQ again results in successful transfer of the command.
Modbus/TCP channel aborted during
power cycle
After powering up an RX7i running Modbus/TCP client channels, the
establish connection occasionally fails because the server occasionally
rejects the "open" from the client. The connection will then succeed if the
application retries the open when it sees a 0x9690, 0xAA90, or B490H
response to an open request or to the first write request.
RX7i response timeout errors (8/08) in
Ethernet exception log under extremely
heavy SRTP traffic
Under extremely heavy SRTP traffic conditions, the Ethernet Interface
may log an event in the Ethernet exception log (Event 8, Entry 2 = 08H)
indicating an overload condition. This error terminates the SRTP
connection. If this event appears, either the traffic load should be
reduced, or the application should use an alternate communications
method to verify that critical data transfers were not lost due to the
overload.
SRTP channel transfers may take up to
20 seconds after power cycle
When SRTP communications are interrupted by a power cycle, the
Ethernet interface may require up to 20 seconds to reestablish TCP
connection used for SRTP communications.
