3. 8. 1. Reminder of the possible connection methods: Same as existing

1 = GND

2 = Tx

3 = Rx

3. 8. 2. Configuring the drive address on the Modbus Plus network

On the Altivar 38’s Modbus Plus option card, the drive address is coded using switches 1 to 6 (LSB to MSB).

Therefore, simply transfer the switch configuration of a Modbus Plus option card for Altivar 38 to the switches of a Modbus Plus option card for Altivar 61.

The address corresponds to the binary number given by position 0 or 1 of the 6 switches increased by 1.

E.g., address 6 = 5 (+1)
