Do not dispose of this device in the trash along with other waste!
According to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collec� on, as well as to store the occasion of
the purchase of new equipment (in accordance with the principle of old-for-new, regard-
less of brand). Electro thrown in the trash or abandoned in nature, pose a threat to the
environment and human health.
Purpose
The MR-RO-1 module is used as an external device that extends re-
lay outputs of the PLC programmable controllers or other devices
in which data is exchanged via the RS-485 port with Modbus RTU
protocol.

  • Page 1 Electro thrown in the trash or abandoned in nature, pose a threat to the environment and human health. Purpose The MR-RO-1 module is used as an external device that extends re- lay outputs of the PLC programmable controllers or other devices in which data is exchanged via the RS-485 port with Modbus RTU protocol.
  • Page 2: Working Modes

    Functioning The MR-RO-1 module is equipped with a controllable relay output (separated contact). The output operates according to the preset mode of operation and parameters assigned to it. The setting and reading the output status, operation parameters and adjustment of all communication and data exchange parameters is carried out via RS-485 port using Modbus RTU communication protocol.
  • Page 3 Another ON command received at the time T1 or when the relay is already switched on will be ignored. Mode 2. Activation for a preset time The relay activates after receiving the ON command, and deac- tivates when the preset time is up. Next cycle can be initiated by sending the next ON command.
  • Page 4 Mode 4. OFF/ON cycle Cyclic operations OUT OFF (relay off) for the time T1 and OUT ON (relay on) for the time T2. The cycle is started by sending the ON command. The number of executed cycles depends on the 0x235 registry value.
  • Page 5 off. Sending the OFF command during the cycle breaks its execu- tion and turns off the relay. The ON command received during cycle execution will be ignored. After the programmed number of cycles the next ON command starts the program from the beginning.

  • Page 7 Mounting Recommended use of interference and surge filters (e.g. OP-230 from the F&F offer). It is recommended to use shielded twisted-pair cables to connect the module to another device. When using shielded cables, ground the screens only on one side and as close to the device as possible. The ends of the signal line should be terminated with termination modules (e.g.

Starting the controller with the jumper closed restores the factory settings of the communication parameters. To do this, remove the casing of the module and put the jumper on both pins.
