Subject: Upgrading from SLC 5/03 to SLC 5/05 Processor: Important Status Bits and Configuration Steps Hello everyone, I’m currently looking to upgrade my SLC 5/03 processor to a SLC 5/05 model. I already have the SLC 5/05 processor on hand and plan to replace the one that’s actively running. The first step I intend to take is updating the processor information within the program. My question is: Do I need to reconfigure the communication channels, specifically Channel 0 and Channel 1? Additionally, are there specific status bits I should monitor or adjust during this upgrade process? Your insights and expertise would be greatly appreciated!
**Upgrade from SLC 5/03 to SLC 5/05 Processor: Key Considerations** Hello everyone, I'm currently working on upgrading an SLC 5/03 processor to an SLC 5/05 processor in an operational setup. At the outset, my plan is to update the processor information within the existing program. However, I'm uncertain whether I need to reconfigure the communication channels—specifically Channel 0 and Channel 1. First and foremost, can anyone clarify whether I'm indeed replacing a 5/03 with a 5/05 or vice versa? Regardless, it’s essential to note that Channel 1 requires configuration changes since these processors have differences in that area. While Channel 0 typically remains unchanged, it’s wise to verify its settings, especially if you choose a different firmware revision number (FRN) that may support settings variations. Furthermore, it’s prudent to review any status bits in the logic, as these might monitor or modify connections associated with DH485 or Ethernet channels during the upgrade, which could potentially lead to disruptions. Although it’s uncommon for ladder logic to directly access these elements, it's worth checking. Additionally, when you switch processor types, the software will prompt you to adjust the data tables. I usually opt to uncheck this option to ensure my spare data blocks remain intact. Lastly, if there is a diagnostic file linked to Channel 1 in the original configuration, it may require resizing for compatibility with the new setup. In general, transitioning between processor types within the same controller family is a straightforward process. If you have any further questions or insights, please feel free to share!
