IO redundancy
You can configure two identical modules redundantly. To do so, plug both modules into a
redundant terminal block side by side. You can find additional information on mounting
modules in an IO redundancy configuration in the ET 200SP HA System Manual, section
"Installing", "Installing terminal block".
In IO redundancy mode, the left module is the master and the right module is the slave.
Both redundant modules measure simultaneously and independently in the process. Both
redundant modules generate diagnostics, alarms and process values. The process values are
based on the measured values of the respective leading channel that measures with low
resistance in the process. By default, the channels of the master are the leading channels.
When a module fails or when the failure of a channel is detected, the respective leading
channels are switched over to the partner module. Once an error has been corrected, there is
no changeover of the leading channels involved.
HART communication can only take place over the leading channel.
Measurement type/measuring ranges
The I/O module supports the following measuring ranges:
Measurement type
Disabled
Current (2-wire transducer)
The resolution of the analog values is dependent on the interference frequency suppression
setting.
HART mode is only possible with a measuring range of 4 to 20 mA. HART communication is
not interrupted even at currents below 4 mA.
An overview of the measuring range and the overflow, overrange, etc. can be found in section
Configurations of the AI 16xI 2-wire HART HA I/O module (Page 13).
Diagnostics encoder supply
The sensor supply of the analog input is monitored for overload and short-circuit to M.
