Prior to Release 6.71 for the RX7i, the Modbus RTU slave protocol would return
an Invalid Function Code error response (1) upon receipt of a request with an
invalid or undefined function code. Starting with Rel 6.71, the Modbus RTU slave
ignores requests with an invalid or undefined function code, and no response is
sent.
Block name now provided in User
Application faults
In previous firmware versions, the fault entry for a non-fatal application fault (for
example, reference-out-of-range) provided numeric information to identify the logic
block causing the error. However, the user did not have a way to correlate the
numeric information with the name of the block. The new firmware includes the
first 12 characters of the block name in the fault entry.
Undefined symbols in C Blocks In Release 5.00 or later, if an attempt is made to download a C block containing
undefined symbols, the download will fail. Machine Edition will display the
following message in the Feedback Zone: Error 8097: Controller Error – Controller
aborted the request [0x05][0xFF]
Prior to Release 5.00, C blocks containing undefined symbols could be
successfully downloaded, but if they were executed the CPU would transition to
Stop/Halt mode.
Length of Serial I/O buffer (Release 5.0 or later) The "Set Up Input Buffer Function" will always allocate a
buffer containing 2049 bytes. This is one byte more than previous PACSystems
releases.
Only one BTM allowed in main
rack
Only one BTM is allowed in the main rack. Multiple BTMs in the main rack will
result in undefined operation.
Upgrading firmware with
modules in rack
The process of upgrading the CPU firmware with the WinLoader utility may fail
when multiple IO modules are in the main, remote or expansion racks, due to the
time it takes to power cycle the rack system. If the upgrade process fails, move
the CPU to a rack without IO modules and restart the upgrade process.
Service Request 13 command
block must contain zero
When the Service Request function block is used to invoke Service Request 13,
the first word of the command block sets the number of last scans to be executed.
If the value of that word is -1 (or 0xFFFF), then the number of last scans is set to
the value in the configuration.
Changing IP Address of
Ethernet interface while
connected
Storing a hardware configuration with a new IP address to the RX7i while
connected via Ethernet will succeed, then immediately disconnect because the
RX7i is now using a different IP address than the Programmer. You must enter a
new IP address in the Target Properties in the CME Inspector window before
reconnecting.
