MAC Address DIP Switch (DS1)
MAC addresses for BACnet and Modbus communication, are selectable by DIP switch DS1 using binary logic.
BACnet
- The highest MAC address is 254.
- Default is all switches OFF = MAC address 0

Modbus
- The highest MAC address is 247.
- Default is all switches OFF = MAC address 1

- There is no device instance for Modbus.
| MAC Address | DS.1 = 1 | DS.2 = 2 | DS.3 = 4 | DS.4 = 8 | DS.5 = 16 | DS.6 = 32 | DS.7 = 64 | DS.8 = 128 |

LEDs
Power
On = Input voltage normal
Off = No power
Status
Flashing = Normal operation (watchdog)
RX/TX (BACnet)
Flashing = Receiving (RX) and/or transmitting (TX) data.
RX/TX (Modbus)
Flashing = Receiving (RX) and/or transmitting (TX) data.
Input Status
On = Input on
Off = Input off
Flashing = Input not connected (thermistor setting only)
Analog = When Universal Inputs are set to analog values (Vdc, mA, or Thermistor); the LED intensity corresponds to the input value. For example: At 10Vdc, the LED will be fully on. At 5Vdc, the LED will be at 50% intensity. At 0 Vdc, the LED will be off.
Output Status
On = Activated
Off = Deactivated
Flashing = Output pulsed
Analog = When Universal and Analog outputs are set to analog values (Vdc); the LED intensity corresponds to the output value. For example: At 10Vdc, the LED will be fully on. At 5Vdc, the LED will be at 50% intensity. At 0 Vdc, the LED will be off.
Network Conditions
Please note that all jumper settings must also be set to the same value through BACnet or Modbus. The following is a list of conditions and additional BACnet or Modbus objects.
Universal Inputs (AI1-AI4)
- For temperature thermistor reading: with the jumper set to Thermistor, set the AI input type to 10K_TypeG, 10K_Type3A1, 10K_Type4A1, 10K_NTC, 20K_Type6A1 or 30K_Type6A1.
- For on/off contact input reading: with the hardware jumper set to Thermistor, set the AI input type to Digital_Input. The polarity can also be set to direct or reverse. For example, in Reverse an “on” signal would be recognized as an “off” signal.
- For analog 0-10 Vdc input reading: with the hardware jumper set to 0-10 Vdc, set the AI input type to 0_10V.
Universal/Analog Outputs (AO1-AO2)
- You can set the polarity to direct or reverse. For example, in reverse the output range would be 10-0 Vdc instead of 0-10 Vdc. The polarity applies to all settings 0-10Vdc, on/off and pulsed.
- You can also set the outputs to pulsed or digital on/off.
- A fixed output value can only be modified via BACnet when the override switch is in the “Automatic” position.
Binary Outputs (BO1-BO4)
- A fixed output (open/closed) can only be modified via BACnet when the override switch is in the “Automatic” position.
- The displayed text can be set to either Open/Closed, On/Off, or Alarm/Normal (BACnet only).
Supervised Outputs
- All outputs are fully supervised via BACnet. This provides the actual state of the output including any manual overrides done using the on-board switches.
Pulse Counting Feature
The pulse counting feature enables counting the number of pulses detected by the inputs.
- When an active edge is detected, the Pulse Count is incremented by 1 up to the Prescaler value. When the Prescaler value is reached, the Accumulator is incremented by 1 and the Pulse Count is reset to 0.
- A value that is higher than 80% of the input’s saturation confirms a high level. A value that is lower than 20% of the input’s saturation confirms a low level.
- The maximum frequency is 100Hz and the minimum pulse length is 5ms/50%D.C.
Output Configuration
Output LEDs LD1 and LD2 will always respond to the output mode selected on MSV.54/55 and the analog value set on AV.72/73 irrespective of the position of JP1 and JP2. The position of JP1 and JP2 determines the output objects to be used as shown below:
| JP1 and JP2 Position | Output Objects to be used | ||
| JP1 in Analog Position | AV.52, AV.54, AV.72, AV.506, BV.66, MSV.54, MSV.110 | ||
| JP2 in Analog Position | AV.53, AV.55, AV.73, AV.507, BV.67, MSV.55, MSV.111 | ||
|
JP1 in Binary Position |
Common | MSV.100 = TPM | MSV.100 = On/Off |
| MSV.100 | AV.500 | BV.22 | |
| MSV.106 | MSV.66 | ||
|
JP2 in Binary Position |
Common | MSV.100 = TPM | MSV.100 = On/Off |
| MSV.101 | AV.501 | BV.23 | |
| MSV.107 | MSV.67 | ||

Modbus Registers
- Register address
- As per the protocol base (base 0); for PLC add 1 to the protocol base.
- As per holding register (base 40001)
- Functions :
- 03 Read Holding Register
- 06 Write Single Register
- 16 Write Multiple Registers
- Error Codes :
- 02 Illegal Data Address
- 03 Illegal Value
- 06 Slave Device Busy
- W = Writable register, [blank] = read-only.
- No Real number in Modbus register, use scale to calculate real number. Register = Real number * Scale => Real number = Register / Scale. Scale could be 1, 10 or 100
- Attention when writing a register that contains a bit string. If bit is writable (conditional or not), the write will always be accepted. If bit is reserved or not writable, the write will be ignored and will keep its actual state.
- Use the READ-MODIFY-WRITE sequence.
