    Modbus master, allowing greater flexibility in the field. RM169-1 uses routing tables to obtain fewer collisions in complex networks and can also be used as a Modbus hub, allowing 8 Modbus modules (inputs and/or outputs) to be connected through the RS-485 port. (RM169-1 will power these modules).

    RM169-1 User Manual 11. OPERATING MODES AND SETTINGS MIRROR OPERATING MODE 11.1. In Mirror mode, the status of digital inputs of an unit is replicated on digital outputs of a remote unit and vice versa. In this operating mode, data communication on the serial line is not allowed. The mirror mode can only work between two radiomodem units (point-to-point) and can use digipeater (up to 8) to extend the route of the radio link.
  • Page 16 RM169-1 User Manual Slave / Master: Allows you to select the functionality of the radiomodem between Master and Slave. The unit configured as Master uses the energy saving and transmits as a result of events. The unit configured as a Slave is always active and never takes the initiative of the transmission.

  • Page 17: Modbus Low Energy Operating Mode

    RM169-1 User Manual Target address: Contains the value of the destination address and must be equal to the address of the other unit. Example: Master unit: Its address = 1; Target address = 2. Slave Unit: Its address = 2; Target address = 1.It is evident that the addresses of the two fields (its own address and the and target address) are reversed between Master and Slave.
  • Page 18 RM169-1 User Manual Slave / Master: Allows you to select the functionality of the radiomodem between Master and Slave. The unit configured as a Master uses the energy saving and transmits due to events. The unit configured as a slave is always active and never takes the initiative of the transmission.
  • Page 19 RM169-1 User Manual Modbus timeout: Represents the time interval (in hundreds of milliseconds) within which the modbus answer on the packet sent by the Master unit must be received. Cycle Update: In this field the time of the periodical transmission is set. The time base is selectable between seconds, minutes or hours.
  • Page 20 RM169-1 User Manual Serial port: In this frame (collection of options) the parameters choice of the serial line is performed. In the Master units, these parameters configuration is referred to the data exchange between the radiomodem and the external Modbus node. In the Slave unit, these parameters configuration is referred to the data exchange between the radiomodem and the SCADA application.

  • Page 21: Modbus Operating Mode

    RM169-1 User Manual MODBUS OPERATING MODE 11.3. This mode of operation provides one Master unit (star centre) and one or more slave units. The Master unit must be connected via the serial interface to a PC (or PLC) on which a SCADA application is running, which uses the communication protocol Modbus RTU.
  • Page 22 RM169-1 User Manual respecting maximum limit nodes each slave unit. Slave / Master: Allows you to select the functionality of the radiomodem between Master and Slave. The units configured as a slave never takes the initiative of the transmission. Internal node address: It is the address of the modbus node related to the internal peripherals of the radiomodem.
  • Page 23 RM169-1 User Manual Safety options (frame): Time: sets the value of the safety timer whose time base is selectable between minutes and hours. If the radio doesn’t receive a valid packet within the selected time interval, the digital output (relay) is forced to a condition chosen in the field "Relays to Open/Closed".
  • Page 24 RM169-1 User Manual System Code: it is the system code of the radiomodem. The purpose of this parameter is enabling the communication only between those units that have the same system code value. This value must be the same for all the radiomodem in the network.
  • Page 25 RM169-1 User Manual In the "modbus standard" mode you can enable the LBT feature: the radiomodem waits that the active channel is free before transmitting the radio packet. When the LBT function is active the device counts the seconds of data ON-AIR transmission in order to operate according to EN300 220-1 standards that require to not exceed a transmission time of 100 seconds in a 1 hour period.

  • Page 26: Radiomodem Operating Mode

    RM169-1 User Manual RADIOMODEM OPERATING MODE 11.4. This mode of operation is normally used for the exchange of data between different locations. In the same network the presence of a master unit as well as of one or more slave units is expected. If the power save feature is not used, each unit can receive data via the serial port RS485 (except during radio communications) up to a maximum of 1024 bytes.
  • Page 27 RM169-1 User Manual Safety options (frame): Time: sets the value of the safety timer whose time base is selectable between minutes and hours. If the radio doesn’t receive a valid packet within the selected time interval, the digital output (relay) is forced to a condition chosen in the field "Relays to Open/Closed".
  • Page 28 RM169-1 User Manual Rx Address For Tx: If enabled, the radiomodem stores the full address (digipeaters and target address) of the unit from which it received the last packet and uses these addresses to send the data received from the DTE connected to it. This function is available only if "Address from DTE"...
  • Page 29 RM169-1 User Manual Repetition Number: In this field you can define the number of repetitions of the packet if the acknowledge is not received. This function is available only when the ACK is enabled. Nak To DTE: If enabled, the radio modem sends a NAK character (ASCII 21) to the DTE in the case where all repetition are sent without receiving any acknowledge.

    RM169-1 User Manual 12. UTILITY Link Test 12.1. The access to this page is only allowed if, on the first page of the configurator, the "radiomodem" modality is chosen. On this page you can test the communication with the remote radiomodem, valuate the quality of the radio signal and the level of the battery voltage on the selected units.

These values enable the assessment of the intensity of the radio signal received both from the remote and local units. The RSSI fields are expressed in dBm and have a resolution of 0,0625 dbm. In another box the value of the supply voltage of the remote radiomodem is displayed.
