Restriction/Open Issue Description

Hardware configuration Not 

Equal after changing target 

name.

If you store a hardware configuration to flash that sets Logic/Config Power-up Source to 

Always Flash or Conditional Flash and then change the name of the target in the 

programming software, the hardware configuration will indicate Not Equal and will not verify 

as Equal. 

Controller and IO Fault Tables 

may need to be cleared twice 

to clear faulted state.

Both Controller and IO fault tables may need to be cleared to take the CPU out of Stop/Fault 

mode. If one of the tables contains a recurring fault, the order in which the tables are cleared 

may be significant. If the CPU is still in Stop/Fault mode after both tables are cleared, try 

clearing the fault tables again. 

Setting Force On/Off by 

storing initial value.

Once a force on or force off has been stored to the controller, you cannot switch from force 

on to force off or vice-versa by downloading initial values. To turn the force on or off, 

download the project.

Number of active programs 

returned as zero.

The SNP request Return Controller Type and ID currently returns the number of active 

programs as zero.

Serial I/O fails at 115K during 

heavy interrupt load.

Rare data corruption errors have been seen on serial communications when running at 115K 

under heavy interrupt load on the controller. Under heavy load applications, users should 

restrict serial communications to 57K or lower.

Multi-drop serial 

communications interrupted 

by CRU320 power cycle

Communications can be disrupted when two EIA485 ports (COM 2) are wired together/multidropped using a two wire connection (wired OR) and either CPU is powered on while the 

other CPU is communicating.

SNP ID not always provided. Unlike the Series 90-30, the RX3i CPU’s SNP ID does not appear in the Machine Edition 

programmer Show Status display. Service Request 11 will always return zeros.

Second programmer can 

change logic while in Test & 

Edit mode.

While currently active in a Test and Edit session using Machine Edition on one PC, Machine 

Edition running on another PC is not prevented from storing new logic to the controller.

Must have logic if powering up 

from flash.

If the application will configure the CPU to retrieve the contents of flash memory at power-up, 

be sure to include logic along with hardware configuration when saving to flash memory.
