i have make FMS PROFIBUS connection between two s7-300 plc via CP PROFIBUS

all communication parameters are well it make me green led (connection ready to send variables)in netpro view,i have configured the commnication variables in server which they willbe  converted by the CP  to FMS structure  ,this structure must read by the client via GetOD requet in order to have the symbolique name of communication variable

when i put FB3 in the client program  the parameter of the bloc VAR1 did not accept  communication  variable adresse knowing that this parameter point to the area of communication variables that must be read from serveur PLC

what must i do to solve this situation?

you find in the attached file screen shoot of different step of configuration and also for diagnostic NCM
