0739P300-E Installation Supercal 739 EN 17-03-2016 9 Sontex SA, 2605 Sonceboz, Switzerland
Communication interface and options
The communication interfaces are installed and preset in the factory. When ordering, you must specify the interface type: remote powered M-Bus, Radio
Supercom or Wireless M-Bus (OMS) and pulse outputs.
Pulse input function
Depending on the defined variant, the Supercal 739 offers the possibility of advantageously integrating up to two further pulse input meters, for instance a
hot water meter and a cold water meter.
The value of the pulse factor is programmable via the Prog739-749 software. By default, the pulse factor will be 1 Pulse/Unit for each pulse input.
The meter data are aggregated separately in totalizers and can be shown on the display as IN1 and IN2; they can also be transferred via the communica-
tion interface which is installed in the integrator.
The Supercal 739 is delivered with a cable length of 1.5 m for the pulse meters.
Pulse output function
Depending on the defined variant, Supercal 739 offers the possibility of integrating two open collector pulse outputs which can represent hot energy, cold
energy or volume.
Thermal version:
- Output S1 = Hot energy
- Output S2 = Volume
Thermal/cooling version:
- Output S1 = Hot energy
- Output S2 = Cold energy
Whenever the smallest energy unit (hot or cold) and/or volume displayed on the screen is incremented, 1 pulse will then be transmitted on the correspond-
ing output cable S1/S2.
Example for energy:
Display 12345678 kWh ==> output pulse value for energy = 1 kWh / pulse
Display 12345,678 MWh ==> output pulse value for energy = 0.001 MWh / pulse
Display 123456,78 GJ ==> output pulse value for energy = 0.01 GJ / pulse
Example for volume:
Display 12345,678 m
3
==> output pulse value for volume = 0.001 m
3
/ pulse
Display 123456,78 m

/ pulse
The Supercal 739 is supplied with a cable length of 1.5 m for pulse outputs.
Electrical characteristics of the pulse outputs: open collector 1 Hz 500 ms.
Optical interface
The optical interface is installed by default on each Supercal 739.
Communication between the Prog739-749 software and Supercal 739 can be effected with an optical coupler.
The transmission speed via an optical coupler is set at 2400 bauds and cannot be changed.
We recommend the use of optical couplers supplied by: www.petechnik.de
Should communication problems be encountered, please refer to the document User Guide Prog739-749 (integrated as PDF in the software).
Configuration recognised by optical couplers: For the optical probe listed below, we have noted the filters needed to permit correct communication with
Pro739-749 software:
Optical probe Filter
P+E Technik : "K1-98" or "K1-06" No filter
P+E Technik : "K01-USB" No filter
Supercom Radio
The Supercom Radio communication interface permits communication between all Supercom Sontex radio products. For this communication interface to
be available, it must be specified when the order is placed. The radio module will therefore be installed and configured in the factory.
Supercom Sontex units make use of a bi-directional radio technology which is a reliable solution with high performance for a remote metering system (fixed
or mobile). The technology employed is based on MFD and Radian 0 protocols and works at a frequency of 433.82 MHz.
The units fitted with the Radio module can be accessed 365/365 days per year from 06:00 to 20:00.
The radio address is displayed in the Service menu if it corresponds to the serial number of the Supercal 739.
Technical data of the radio communication system:
Bi-directional communication; FSK Modulation; Frequency 433.82 MHz; Radian 0 radio protocol.
The life cycle is calculated for normal metering. Factors such as: the environmental temperature during use, the number of readings taken etc.
influence the battery service life.
Wireless M-Bus Radio
The radio module Wireless M-Bus is used to transfer data according to the wM-Bus (EN13757-4) radio communication protocol and in compliance with the
OMS (Open Metering System) Release V3.0.1. To have this interface of communication available, it will be necessary to specify by ordering. The radio
module Wireless M-bus will be installed and configured at the factory. A specific notice will be added with the standard documentation.
Powered remote M-Bus
The powered remote M-Bus communication interface is a serial interface which permits communication between different M-Bus devices via a central M-
Bus station (per example: Sontex 634). For this communication interface to be available, it must be specified when the order is placed. The powered re-
mote M-Bus module will therefore be installed and configured in the factory.
The M-Bus protocol is compliant with standard EN1434-3.
By default, the primary address will be configured with the address 0 and the secondary address will correspond to the serial number of the Supercal 739.
To change the value of the secondary address, you must use Prog739-749 software or send M-Bus specific orders. The secondary address corresponds to
the identification field ID.
The primary address is displayed in the Service menu with the indication [Addr:].
Technical data for the M-bus communication system:
M-Bus protocol compliant with standard EN 1434-3; free potential interfacing without polarity (the voltage measured on the last device must exceed
36VDC); transmission speed 300/2400 Baud; variable data structure. A M-bus device is seen as two M-Bus charges by the Master.
Type of cable recommended: telephone cable JYStY N*2*0.8 mm
