Before OS Upgrade
NOTE: The PLC program and data must be saved before starting the upgrade process.
CAUTION
IRREPARABLE EQUIPMENT DAMAGE
Do not use a .bin file located on the network. If the network access were to go down, it would interrupt the download process and cause irreparable damage to the device.
Failure to follow these instructions can result in injury or equipment damage.
NOTE: Download of the firmware may not operate correctly when performed through a Modbus Plus network with several nodes. In this case, please transfer the firmware through a peer to peer mode between the PC and the PLC.
During Download
CAUTION
IRREPARABLE EQUIPMENT DAMAGE
During OS transfer:
  • Never interrupt the power supply to the CPU.
  • Never interrupt the OS transfer process.
  • Never interrupt the communication between PC and PLC.
Interrupting the transfer process before it has completed can cause irreparable damage to the device.
Failure to follow these instructions can result in injury or equipment damage.
Upgrade Duration
The upgrade action using Modbus or Uni-Telway can take more than an hour.
Downgrade Processors
NOTICE
PROCESSOR DAMAGE
Do not download a firmware V2.31 or lower in the processors listed below, otherwise, you will not be able to change the firmware version:
  • 140 CPU 65 150 / 150C / 160 / 160C PV ≥ 15
  • 140 CPU 67 160 / 160C PV ≥ 13
Failure to follow these instructions can result in equipment damage.
NOTICE
ETHERNET COPROCESSOR DAMAGE
Do not download a firmware version V2.8 or lower in the CoPro Ethernet Port of processors listed below:
  • 140 CPU 65 150 / 150C /160 / 160C PV ≥ 27
  • 140 CPU 65 260 PV ≥ 14
  • 140 CPU 65 260C PV ≥ 11
  • TSX P57 4634M PV ≥ 22
  • TSX P57 4634MC / 5634MC / 6634M PV ≥ 10
  • TSX P57 5634M PV ≥ 27
  • TSX P57 6634MC PV ≥ 08
Do not download a firmware version V2.82 or lower in the CoPro Ethernet Port of processors listed below:
  • TSX H57 24M PV ≥ 09
  • TSX H57 24MC PV ≥ 08
  • TSX H57 44M PV ≥ 10
  • TSX H57 44MC PV ≥ 08
Otherwise, you will not be able to use the Ethernet link anymore (for Hot Standby processors, it means the Hot Standby functionality will not work anymore). The operation is not reversible.
Failure to follow these instructions can result in equipment damage.
PLC in Stop Mode
The PLC must be stopped during the download.
