If the GT200-HT-DP is configured as PROFIBUS DP slave, it has no effects. 2.4 Address Setting Button The address setting button is located on the front panel of the GT200-HT-DP. It’s used to set the PROFIBUS DP/Modbus address (range: 0 to 99). -
Page 9: Resistor Switch
2.5 Resistor Switch The GT200-HT-DP has an internal series resistor (270 Ohm, 2 W) required for the HART channel, that allows up to 13 HART instruments to be connected. When the power of the series resistor is more than 2W, you must use an external series resistor (250 Ohm, 3 W), allowing the gateway to be connected to up to 15 HART instruments. -
