2600 Family Instruction Manual 16 Chapter 3 : IOM Gateway
Response none
Notes This action clears all of the specified bit flags in
the Status byte (Section 3.4.1), which is present
in every ModRsp.
The specified bit flags are cleared before the
ModRsp is generated. As a result, the Status byte
returned in a ModRsp reflects the changes that
were caused by any ResetFlags actions
present in the associated ModCmd.
Except for the HRST (hard reset) bit flag, any
combination of bit flags may be cleared by the
Ethernet client. The client is not permitted to
clear the HRST flag because this flag is reserved
for gateway-to-IOM link control.
3.9.6 SetWatchdog
Function Programs the MM’s communication time-out
interval.
Opcode 0xF3
Command (Interval)
Response none
Notes The MM employs a timer to detect the absence of
communications between the Ethernet client and
the gateway. If no communications are received
from the client within the specified time-out
interval, the communication timer will time-out
and the MM will execute a hardware reset. This
behavior ensures that all I/O will be turned off in
the event the client shuts down abnormally.
The watchdog interval defaults to 10 seconds
(Interval = 100) in response to a MM reset.
If the default interval is suitable for the
application, no SetWatchdog action need be
issued to the MM.
Upon receipt of a SetWatchdog action, the
new watchdog interval is effective immediately
and the watchdog timer is reset so that it will time
out when the new interval elapses.
3.9.7 GetProductID
Function Returns the MM’s model number.
Opcode 0xF5
Command none
Response (ModelNum<15:8>),(ModelNum<7:0>)
3.9.8 GetVersion
Function Returns the MM’s firmware version number.
Opcode 0xF6
Command none
Response (MajorVer),(MinorVer)
Notes On firmware labels, the major and minor version
numbers are printed with a decimal point
delimiter. For example, printed version “1.02” is
indicated by MajorVer = 1, and MinorVer =
2.
