void ps64_get_all ( PS64_INFO * info )

Establishes the communication to the SPS controll unit for reading, reads the data and stores them in the local structure

ps64_data

. Since the communication sometimes fails, an error protocol system is implemented as well. It record the errors over a period of 10 min. and sends them (cm_msg) to midas.

Parameters

info	is a pointer to the DD specific info structure
