ParameterDescriptionValues
RF Mesh ModeEnable or disable RF Mesh mode.Enabled
Disabled
RF Address ModeRF Address modeAddress Mode 0: In this mode, the device broadcasts all packets to other ModProBus devices in the network.
Address Mode 1: In this mode, the device can broadcast to all ModProBus devices in the network or send to a specific ModProBus device specified in the network.
Address Mode 2: In this mode, the device can broadcast to ModProBus devices in other networks or send to a specific ModProBus device specified in the specified network.
RF Device IDThe RF device ID of the device. Each device's ID must be unique.1-254
RF Network IDThe RF network ID of the device. The ID must be the same for devices in the same network.0-254
RF Repeater ModeIf enabled, this device will repeat all messages that do not come with its own RF Device ID and all broadcast messages.Enabled
Disabled
RF Repeater NumberThe total number of Repeaters in the network. The number must be the same for devices in the same network. As the number increases, the maximum transmission time and packet collision will increase.0-255
RF Repeater Number of SlotsThis is the total number of repeater slots in the same frequency channel. The number must be the same for devices in the same network. When multiple repeater devices are used in a single network, if all repeater devices send the received packet at the same time, the repeated data packets may collide in the frequency channel. To prevent this, the frequency channel is divided by the RF Repeater Number of Slots, and each repeater randomly selects a specific segment. This value must be greater than the RF Repeater Number value; otherwise, data packets will collide. As the RF Repeater Number of Slots value increases, the maximum transmission time will increase.1-255
RF ProfileThe operating profile of the device.Profile 0
Profile 2
Profile 4
Profile 7

RF TX TimeoutThe timeout duration for the transmitted RF message (milliseconds).
RF RX TimeoutThe timeout duration for the received RF message (milliseconds).

  • All ModProBus devices in the same network must be configured with the same mesh mode.
  • All ModProBus devices in the same network must be configured with the same Address Mode.
  • Address Mode 1 and Address Mode 2 can only be used when mesh mode is enabled.
  • Users should consider that as the number of repeaters increases, the probability of packet collision and maximum transmission time increases.
  • Users should consider that as the number of repeater slots increases, the maximum transmission time increases.
  • Profile 4 has the lowest data rate and the longest range. Profile 2 has the highest data rate and the shortest range.
  • Profile 4 can only be used when mesh mode is disabled.
  • All ModProBus devices in the same network must be configured with the same frequency.
  • When using mesh mode, RF RX timeout must be more than twice the maximum transmission time value.
