The settings for the serial interface are described as the transfer mode.
The following options are available:
y
1 start, 8 data, 1 stop bit, even parity (8E1)
y
1 start, 8 data, 1 stop bit, uneven parity (8O1)
y
1 start, 8 data, 2 stop bit, no parity (8N2)
y
1 start, 8 data, 1 stop bit, no parity (8N1)
The transfer mode can be changed via Modbus® or the call-up buttons.
Supported baud rates: 1200, 2400, 4800, 9600, 19200 and 38400 baud.
Inputs and outputs
Input
In the two-tariff version, the meter can be equipped with a control input
for tariff switching.
Outputs
The meter has 2 potential-free S0 pulse outputs (as per EN 62053-31)
or 2 potential-free MOSFET pulse outputs (semiconductor relay).
The MOSFET outputs are designed as normally open contacts.
Secondary pulse outputs
Set transformer factors do not affect the pulse outputs.
The pulse duration is 30, 50, 100 or 500 ms, depending on the device
version.
Depending on the device version, the energy pulses (R
A
) are 1, 10,
50, 100, 500, 1 000, 5 000, 10 000, 50 000 or 100 000 pulses/kWh or
pulses/kvarh and are always obtained in secondary form.
Primary pulse outputs
Set transformer factors affect the pulse outputs.
The pulse duration is 100 or 500 ms, depending on the device version
and the set transformer factors.
