v2.1 of the MultiSmart Pump Station Manager will be released in the next week or two. There’s some great new features included as well as lots of small enhancements and cosmetic upgrades:

• PID control, e.g. for constant pressure, constant flow via IsaGRAF
• New comms screen making all the communications much easier to setup
• Smart Outflow calculation to cater for high inflow conditions
• Updated DNP3 security (v2)
• Time to spill calculation on the main screen
• Generator functionality (e.g., run time and starts)

More about these features in later posts.

What else is in v2.1?

Fault finding tool – you can enable DNP3 and Modbus logging on the unit, then view the log on the LCD. We’ll do a post later which shows more about how this works in practice and why it’s useful.

Pump Running by External Control – the display shows when the over-ride is running the pumps (known via contactor auxiliary or currents). The main screen shows External Run next to that pump. And the starts and hours run accumulators also update. Thanks to Todd Burnett from Coastal Process & Steve Lahm from North East Water for requesting it (and maybe others as well).

DOUT from multiple sources – you can already do with this with IsaGRAF or the logic engine, but a few customers requested being able to configure a DOUT from a number of sources without using custom logic. So the user interface lets you choose a number of sources and select the “operator” – AND, OR, XOR.

Station Outflow alarm – there are already flow alarms by pump, this has been introduced to cover the complete station.

Cosmetic improvement - holding down a softkey repeats the keypress – greatly welcomed by anyone who has configured lots of faults and digital inputs for example.

Upgrading – the DSP upgrade is automatic, so you don’t have to remember to do that after a firmware upgrade. And when you put in a CF card with an upgrade image the unit prompts you to do an update.

Extra IO blocks in LCD – the Acromag and Adam IO units weren’t fully integrated into the LCD but now have been. Previously the available IO from external units didn’t show up in some of the settings screens (only in the advanced screens), but now do.

Custom names for IsaGRAF tags – the user can rename any IsaGRAF tag as well as change values, making the process a lot more intuitive.
