ALARM HANDLING

NOTE

If the Modbus communication setup has been changed, but the transmitter has not yet started to use the new configuration, then you need to disconnect the HART modem and wait up to 60 seconds for the change to take effect.

In case the MA/MB terminals are used for connection to the HMC, disconnect the RS-485 Converter, cycle power to the transmitter and wait up to 60 seconds for the change to take effect.

The Modbus communication settings will otherwise be lost if you write a new message to the transmitter.

The output from the Modbus transmitter in case of an error (such as a field device malfunction) can be configured. The values for Modbus registers corresponding to PV, SV, TV, and QV will be changed accordingly (applicable registers in area 1300, 2000, 2100, and 2200).

The default alarm output value for each protocol is defined on the next page. Configuring alarm output value is optional.

Use the Modbus string to configure the alarm output. To enter a Modbus string in RRM, do the following (Modbus RTU shown):

1.Start RRM and connect to the transmitter.

2.In RRM, select Setup>General.
