interfaces
The E230 meter has several different communication interfaces:
Optical
test
output
Optical
interface
CS interface (optional)
RS485 interface (optional)
S0 interface (optional)
The optical test output is for verifying the meter operation. The LED
flashes at 1000 imp/kWh.
The optical interface can be used for gathering the meter data in the
field. It is also commonly used for making re-parameterisations and for
the input of formatted commands. The readout protocol is according to
IEC 62056-21 with speeds of up to 9600 bps.
The CS and RS485 interfaces are both optional and can be used for
gathering the meter data in the field. The readout protocol is according
to IEC 62056-21 with speeds of up to 9600 bps (4800 bps), but, of
course, are highly influenced and dependent on the given installation
conditions, cable lengths, etc.
The S0 interface is also optional and can be individually parameterised
for a range of pulse frequencies and pulse durations. In addition, pulse
output 1 S0 interface may also be used for periodical data output, i.e. the
retransmission of data protocol every 30 seconds at 300 bps. This
replicates a proprietary communication data stream as found in the
obsolete ZME meter.
