LeifB Posts: 3 Rating: (0)	Can anybody help In my function I need to set a bico parameter to a high value and afterward to a low value. For this I should use logick "1" and "0" which easily can be set with the starter, but I need to set this from the asyclic writing to parameter. What is the parameter number (and index) for logick 1 and 0 for use by asyclic writing. In the moment I am using digital input binector "not inverted" and "inverted", but general I should use logic 1 and 0.

LeifB Posts: 3 Rating: (0)	Hi, The actual parameter is P 3104 (BI: RTC real time synchronization PING) This parameter is a bico parameter. I have tried to send 1 or 0 but it is not accepting the command. It is a 32 bits (dubble word parameter) to set up with bico parameter. It is accepting e.g. parameter r 0722.4 as a input bico, but is there a parameter for logick 0 an 1 which can bi connectet directly??

There is no such a thing as addressable 0 or 1 in the Drive. Another option is to use AND gate (P20030) or ORgate (P20046) from one of the drives and tie the outputto your parameter and you can change the input to the gate through your acyclic writing.

LeifB Posts: 3 Rating: (0)	Benam, OK, I know how to connect the binectors found in the parameterlist, and this is working. With the tarter you can permanent set the parameteter to 1 or 0. Are Yousure there is no way to set bico parameters directly to 1 or 0 with accyclic writing to the parameter? Thanx and Regards Leif
