Profibus DP Head Station STL-PB1 (Profibus DP)
2 - 6
MITSUBISHI ELECTRIC
2.2.4 Setting the Station Address
The station address (decimal) is determined using two rotary switches on the STL-PB1.
The switch “x1 “ determines the units position of the address, the switch “x10 “ determines the decimal
positions of the address (for example “x1“: 2, “x10 “: 4 -> address = 2 + 10 x 4 = 42).
Valid station addresses are between 1 and 99. The head station also permits the station address 0.
The station address is taken over by the head station after switching on the device (initialization
phase). Adjustments of the switch have no effect during operation.
