Appendix G Module Revision History
Series B Modules as
Direct Replacements for
Series A Modules You can use a 1756- IF4FXOF2F/B module, firmware revision 3.005 or later, as
a direct replacement for a 1756- IF4FXOF2F/A module. When you insert a
series B module into a series A slot, the series A configuration profile works with
the series B module as long as electronic keying is not set to Exact Match.
If Exact Match keying is required in your application, you must remove the
series A module from the I/O Configuration tree and reconfigure it with the
series B profile. The series B module will operate identically to the series A
module as long as the Archiving Connection communication format is not
selected.
Install Series B Firmware For you to have the corrected anomaly and the archiving enhancement for a
series A module, you must install series B firmware, revision 3.005. or later.
If you need to upgrade your existing module, download the firmware and related
files from
http://www.rockwellautomation.com/support/ and use
ControlFLASH™ software to upgrade the firmware.
After you have upgraded the firmware, configure the module. If you do not
intend to use the archiving function, no further action is required. To configure
the module for archiving, see
Archiving on page 38 .
In most cases, a series B module can be used as a direct replacement for a series A
module. Direct replacement of a high-speed analog module at series A with a
module at series B does not require a change to the module’s configuration except
if electronic keying is set to Exact Match. If electronic keying is set to Exact
Match, complete one of the following.
TIP Both series A and series B profiles for the 1756-IF4FXOF2F module will remain
in the software. If you are using a series A module and do not need to use
archiving, then you can continue to use the series A profile:
• If you do not need to use archiving, you can upgrade the module to series B
firmware and use the series B profile by choosing any communication
format other than Archiving Connection.
• If your application requires that replacement modules be the identical
hardware/firmware series, you can downgrade a series B module to
series A firmware available at
http://www.rockwellautomation.com/
support/ .
If your application Then
Does not require replacement modules to
have identical hardware and firmware series Change electronic keying from Exact Match to Compatible Keying.
a. Open the Module Properties dialog box.
b. From the Electronic Keying pull-down menu, choose
Compatible Keying.
Requires replacement modules to have
identical hardware and firmware series Downgrade the series B module to series A firmware available at
