Subject Description
Sequence Store Failure
Writing a very large hardware configuration to flash may cause a “Sequence Store
Failure” error. To work around this error, either:
1. Perform an explicit clear of flash prior to performing the write.
2. Increase the operation timeout used by Machine Edition prior to
performing the write.
IC694MDL754: Must
configure module status bits
Always configure 16 bits of module status when using this module. Configuring 0
bits of module status will result in invalid data in the module’s ESCP status bits.
IC695ALG600 Lead
Resistance Compensation
setting
A configuration store operation fails if a channel is configured for 3-wire RTD with
Lead Resistance Compensation set to Disabled. A Loss of Module fault is logged
in the I/O Fault table at the end of the store operation. Recommendation: to
recover the lost module, change the configuration to enable Lead Resistance
Compensation and power-cycle the module.
C Toolkit PlcMemCopy
Documentation Incorrect
This routine does allow the destination and source pointers to be outside of
reference memory. If the destination points to discrete reference memory,
overrides and transitions are honored.
WinLoader may stop
operating
On computers running Windows 2000 and using some versions of Symantec
Antivirus protection, WinLoader will "lock up" if used in advanced mode. Recovery
requires cycling the computer's power.
Logic and HWC not equal
after power cycle
If the Hardware Config from Target 1, with Logic/Configuration Power-up Source
and Data Source both set to “Always from Flash,” is stored in Flash, then Logic and
Hardware Config from Target 2, with Logic/Configuration Power-up Source both
set to “Always from RAM,” is stored to RAM and there is a good battery, then when
power is cycled the programmer may show that Logic and Hardware Config are not
equal.
The remedy is to clear Flash and then store the Logic and Hardware Config from
Target 2.
RX3i CMX/RMX does not
disable transmitter when the
CPU goes to Stop/Halt
mode.
For IC695CMX128/RMX128 modules, the automatic transmitter disable feature
currently does not work correctly when a controller goes to Stop/Halt mode. When
the CPU goes to Stop/Halt mode or fails and the automatic transmitter disable
feature is enabled the fiber optic transmitter should be turned off, breaking the
reflective memory link. When the feature is disabled the transmitter remains ON
and the reflective memory link will not be broken.
If this feature is enabled, the automatic transmitter disable feature does not work
when the CPU goes into Stop/Halt mode (such as after a software watchdog trip or
multi-bit ECC error detection) leaving the fiber optic transmitter ON. The fiber optic
transmitter is properly disabled if the CPU fails or is lost (for instance the CPU
hardware is removed, the CPU experiences a hardware watchdog event, or
displays a blink code such as a page fault).
This user-configurable feature is enabled by default. The feature may be disabled
by clearing bit 12 with a BUS_WRITE to region 3, offset 0x440.
