I had a similar problem using the IT maintenance configurator. I believe the problem is associated with FBM18's and 39's. I am able to connect to a transmitter on one of these FBM's one time, then I have to do an eprom update on the FBM to connect again. We just use PC 20 now to connect to transmitters on these FBM's. Loyd Greer Great Lakes Chem >>> thierry.mougeot@xxxxxxxxx 06/27/03 07:47AM >>> Hi , I have been using IFDC soft to upload or download transmitter ( 860DP or IPD10 ...) from a WP51D for several years and now I have a problem only with a CP10 . When I try to connect the IFDC to a transmitter of this CP , I read after several seconds this message : "Pass through API could not get a connection to the device . IPC reply : c_worevent CLRECEIVE rtn <-4> event <4> Return -ipc-reply failed : IFDC didn't get a correct immediate reply on his request ( IPC 1st reply failed) . It's the same things with all transmitters in this CP ( there are two FBM18 attached on this CP ). Has anybody an idea ? I would be grateful if you could send me a suggestion. I rebooted the WP51D and I made a checkpoint with success .
