PROFIBUS-DP External Communication Cards

PowerXL DG1 can be connected to the PROFIBUS

using a field bus board. PowerXL DG1 can be controlled,

monitored and programmed from the Host system. The

devices are connected in a bus structure. There is a max of

32 stations (master or slave) can be connected to one

segment bus. The bus is terminated at beginning and end of

each segment. To ensure error-free operation, both bus

terminations must always be powered, if more than

32 stations are used, repeaters are required.
