Hello Ananta, For the meaning of the counter, please refer to the B0193JC user doc, chapter 6. The remedy given there unfortunately doesn't apply to CP's but only to WP's and/or AW's. What it indicates is that there are moments in time that this CP receives far more data than it can handle. So, I am not surprised that from the operators point of view everything looks O.K. because that mainly depends on outgoing data from the CP. You will have to find out why these bursts are there and where they come from. There must be some application (or combination of applications) that send large amounts of data to this CP at certain times. By far the easiest way would be to make a network trace on the CP40B's nodebus and have it analyzed by Invensys. I suggest you discuss this in detail with your local friendly Invensys Service Engineer. Hope this helps.

In the Application Layer "NO RUCBS AVAILABLE" is zero for all controllers and gateways except on one Control Processor 40B. On this module the counter is steady for an hour or two and then jumps at a rate of 600 to 1000 counts per hour for maybe two hours and then settles again. All other processors have this counter at 0. This is a CP40B processor and the loading is only 50%. Data appears to be reaching the operator consoles OK. Does anyone know what this counter means? Thanks, Ananta Candencesol. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
