If I do not have the minimum versions list above, can I still use the ILX34-AENWG?
Yes. Configure wireless parameters using the integrated web pages in the ILX34-
AENWG. Configure the I/O modules using the 1734-AENT Add-On Profile.
Can I use the ILX34-AENWG in safety applications? If so, why is it not red like other safety
products? What safety level is available?
Rockwell Automation makes safety I/O modules for the POINT I/O platform
called POINT Guard I/O™. The safety functionality is in the devices, in this case
a GuardLogix™ controller and POINT Guard I/O modules, and it makes no
difference whether the connection is wired or wireless provided supported RPI
times meet requirements and long enough that nuisance safety trips are avoided.
1734-IB8S - 8 Point Safety Sink Input and 1734-OB8S - 8 Point Safety Source
Output are the two POINT Guard I/O modules available today. The ILX34-
AENWG passes data through to the POINT Guard I/O modules and thus does
not require safety rating and is not red. TÜV Functional safety rated: up to SIL 3,
Category 4, performance Level e.
How many ILX34-AENWGs can I use in one network?
There are two limitations to the number of ILX34-AENWGs that may be used in a
single network - the number of connections supported by the Rockwell
Automation
®
controller or ENET card and the practical limitation of how long the
RPI needs to be to support the required number of connections. For example, the
1756-ENBT and 1756-EN2T Ethernet communications modules support 128 and
256 connections, respectively. If additional connections are required, additional
ENET cards may be used. Rack optimization of discrete I/O helps to minimize
the number of connections. From a RPI perspective, each connection will
increase the minimum RPI time and at some point the RPI may exceed the
maximum allowed by the application. If the RPI is too long, the ILX34-AENWG
network may be segmented using multiple access points operating on non-
overlapping channels.
What if my application requires standalone control or faster sense to actuation time than
supported by the minimum RPI time of the ILX34-AENWG (<20 msec)?
Use the DeviceLogix POINT I/O module - 1734-8CFGDLX that can execute
"locally" and autonomously up to 124 function blocks or ladder logic.
What diagnostic information is available from the ILX34-AENWG?
Wireless performance statistics may be accesses from the web pages of the
ILX34-AENWG, the RSLogix™ 5000 Add-On Profile, or in a HMI software such
as FactoryTalk
®
View using the wireless diagnostic object. Parameters include:
firmware number, link time, parent MAC address, parent data rate, average
signal level, average noise level, transmit packet successes and failures, receive
packet successes and failures, and number of transmit retries.
