1. Installation CPV−DI02 and CPV−CS02
Bus length
1−16
CPV−DI02 (PROFIBUS−DP)
Use a twisted, screened 2−core cable for connecting the field bus.
Cable specification as per EN 50170 (cable type A):
surge impedance:
capacitance per unit length:
loop resistance:
core diameter:
core cross−sectional area:
Exact specifications on the bus length can be found in the
next section and in the manuals for your control system.
CPV−CS02 (ABB CS31)
Refer to the PLC manual for your controller for the type of
cable to be used. Also take into account here the distances
and the field bus baud rate.
