Switch Settings
Rotary Switches
Two rotary switches on the front of the GRT1-PRT, marked x10 and x1, are
provided to set the PROFIBUS device address of the Unit. The address can
be set in the range of 00 through 99 (decimal). The device address on the Unit
must be the same as the address used in the master’s configuration. The
device address is used to uniquely identify PROFIBUS Communication Unit
on the PROFIBUS DP network. Selecting a non-unique address for the unit
will prevent the unit from communicating properly with the Master unit.
In order to set the device address, perform the following steps.
1,2,3...
1.
Turn OFF the power supply before setting the device address.
2.
Set the switch to the (new) device address. Use a small screwdriver to
make the setting, taking care not to damage the rotary switch. The station
address is factory-set to 0.
3.
Turn ON the power again.
Note
1.
Always turn OFF the power to the Unit before changing the device address
setting. The Unit only reads the address setting during the initialization fol-
lowing a power-up, i.e. any changes after power up will have no effect.
2.
The PROFIBUS Communication Unit detects the Master’s communication
baud rate automatically. Setting the baud rate is not required.
