Hi Michael, I think you're out of luck, it appears like this parameter was masked in the MM440 firmwares from v1.1x up to v2.2x (for whatever reason) - so I guess You could call it a bug, and I would expect it is unlikely to be resolved any time soon (if ever) If you really want to transmit alarm codes, there is an alternative option, but it involves a bit more work. You can use the Alarm present bit (r52.7) to trigger an acyclic read of parameter r2110. The parameter still exists, but it is masked from being used in a BICO style connection. Please refer to this document for an explanation of how to achieve this: Note: If you haven't already, the telegram will need to change to a PKW/PZD style i.e. PPO type 1 or 2 https://support.industry.siemens.com/cs/ww/en/view/8894584 Regards, Graeme |
