EN.IO.SGE.25.MODBUS INTRODUCTION 1.1. Purpose of the document The subject of manual are smart level probes: SGE-25.Modbus and SGE-25S.Modbus hereinafter referred to as probes in the manual. The manual applies to the following versions: standard and intrin- sically safe Exi. The manual contains data, guidelines and general recommendations for the safe installation and oper- ation of the probes, as well as procedures in the event of a possible failure.
After receiving the delivery, please refer to the general terms and conditions of contracts available on the manufacturer website: https://aplisens.com/ogolne_warunki_umow.html. 3.2. Transport Transport of probes shall be carried out with the use of covered means of transport, in original packages with diaphragm provided with protection.

Probe identification Depending on the version of the probe, the nameplates may differ in the amount of information and parameters. Table 1 Symbols appearing on the probe’s nameplate...
6.1. General recommendation The probe can be hung on the power cable, e.g. by using from the Aplisens SG cable hanger (item 1 in fig. 1). In the event of frequent removal of the probe or when there is a risk of catching on protruding elements during pulling up, it is recommended to hang the probe on a steel cord using the carrying eye (item 2 in Fig.
EN.IO.SGE.25.MODBUS ELECTRICAL CONNECTION 7.1. Connection, signal output All connection and installation operations shall be performed with disconnected supply volt- age and other external voltages, if used. I Failure to provide proper connection of the transmitter may result in danger. Risk of electric shock and/or ignition in potentially explosive atmospheres. Figure 3 Connection in Modbus network Revision 02.A.001/2022.12...
The electrical connection should be made according to Table. 2. It is recommended to install the PP-Modbus connection box manufactured by Aplisens S.A. to connect the probe cable with the rest of the transmission line. The PP-Modbus junction box is non-hermetic (pressure inside is equal to atmospheric pressure) due to the use of an air filter, which is required for the probe to operate correctly.
Details of RS485 “half duplex” 8.1.3. To ensure the best possible efficiency in industrial environment, the probes from Aplisens S.A. are provided with RS485 transceivers with appropriately customized operating parameters. To provide compatibility and the best possible working conditions, the “Master” transceiver should conform to the specifications below.
It usually ranges from 450 to 650 Ω. If the “Master” device is in fail-safe mode and only works with Modbus transmitters from Aplisens S.A. polarizing resistors are not required. The APLISENS S.A. devices described in this document are NOT integrated with polarizing resistors. 8.1.3.6.
EN.IO.SGE.25.MODBUS 8.2.1. Modbus RTU serial transmission mode Data in the RS485 bus are transmitted serially. As described in the Modbus RTU standard (Modbus over Serial Line Specification and Implementation Guide v1.02), the following formats can be used: − 1 start bit −...
The response time in the APLISENS S.A. transmitters described in this document should be less than 5 ms, including the most disadvantageous conditions (data load, transfer rate).
EN.IO.SGE.25.MODBUS 8.2.3.2. Error handling When messages are transferred between “Master” and “Slave” devices, two main types of errors may arise: transmission errors and “Slave” device errors. Transmission errors, causes: The message received is too short due to e.g. an excessively long interval between bytes con- •...
EN.IO.SGE.25.MODBUS 0x2B (43) ”Read Device Identification” 8.3.1.2. Function used to read, in streaming mode, the basic transmitter identification data, including the man- ufacturer name, product code, software revision. Read Device Identification | 7 bytes request, 46 bytes response | Req: [ADD][FC][0x0E][0x01][0x00][CRC_H][CRC_L] Resp: according to Modbus Application Protocol Specification V1.1 8.3.2.

EN.IO.SGE.25.MODBUS Caution! The measuring range for a scalable integer, including its sign, is in the range of -32767 to 32767 units. If this range is exceeded, a false value will be read. In case of pressure reading in binary format “Signed 16-bit int”, the basic unit should be selected so that 100 times the pressure value does not exceed the above range.

EN.IO.SGE.25.MODBUS Transmitter search parameters related to potential transmission settings must be configured in the opened window. When in doubt, as to the range of settings, the best solution is to tick all the options. Clicking the "Scan" button prompts the programme to start searching for a transmitter, in a sequence, starting from the Configuration mode, and then it will go through an indicated range of transmission speeds and parity in the Modbus mode.

If exceeded, accuracy of measurements using the transmitter cannot be guaranteed. However, the transmitter will continue to process measuring signals up to 50% of the basic range below this point.
EN.IO.SGE.25.MODBUS 8.4.5. Damping and transfer function User can read or modify the measurement damping value and transfer function type. Damping value is expressed in seconds and describes the duration of a non-determined status after which the process variable will achieve 63.2% of the total value change. The process variable value will be nearly fully changed with an accuracy of below 1% after ca 5 time constants.

EN.IO.SGE.25.MODBUS 8.4.10.2. Calibrating the analogue output Select the "Device → DAC calibration" option in the top bar to access the analogue output calibration tab. With the calibration wizard, you can perform a two-point calibration of the low (4 mA) or high (20 mA) current.
EN.IO.SGE.25.MODBUS Table 4 Set range and measurement limits Set range and measurement limits Item Abbr. Meaning "Lower Range Value" – the value of the set range expressed in physical units corresponding to the current of 4,000 mA, i.e. 0% of the output setpoint. The set range cannot exceed the set range limits. The mini- mum width of the set range |(URV-LRV)| is limited to 10% of the base range (URL-LRL).
EN.IO.SGE.25.MODBUS MAINTENANCE 9.1. Periodic inspections Periodic inspections should be carried out in accordance with the standards applicable to the user. Check the processing characteristics by following the steps appropriate to the calibration and configuration procedure described in the EN.IM.PCE.PRE.SGE.MODBUS document available on the manufacturer's website.

EN.IO.SGE.25.MODBUS The set range is defined in the Configuration mode: The set range may be equal to or lower than the basic range. It is defined mostly to configure a trans- mitter to operate in the 4-20 mA current loop mode. In this mode, the start of the set range corresponds to the current of 4mA and the control percentage of 0%, whereas the end of the set range corresponds to the current of 20mA and the control percentage of 100%.
