Use cases
- Send an email alert when the NAMUR status of a pH sensor changes from OK to maintenance required.
- Follow the slope and zero point of each pH sensor between calibrations to see when a sensor ages.
- Plan sensor replacement from the operating hours and the time spent above 80 °C.
- Check on a dashboard when every conductivity sensor was last calibrated.
Installation
Activate Heartbeat Monitoring on the Liquiline CM44x with the activation code from Endress+Hauser.
Connect the RS485 port of the Liquiline to the ModbusCloud Gateway and note bus address, baud rate and parity (factory 247, 19,200 baud, even).
In ModbusCloud add a Modbus device with those settings and import this template.
Delete the channel blocks without a pH or conductivity sensor and check that the selected sensor type of the remaining channels matches.
Things to watch for
All Heartbeat registers read 0. Why?
Heartbeat Monitoring needs an activation code. Without it the Liquiline answers every register in this block with 0.
Float values look like nonsense. What is wrong?
The template uses the factory byte order 1-0-3-2 (CDAB). If the byte order parameter on the Liquiline was changed, set it back or change the byte order of the float registers.
How do I read the date registers?
Dates use the E+H DATETIME format with milliseconds, minutes, hours, day, month and year packed in eight bytes. The template reads them as one raw 64-bit number.
Can I change settings with this template?
No. Heartbeat registers are input registers and read only. Calibration and settings are done on the Liquiline itself or through the main Liquiline CM44x template.
