Hello! Sometimes I have following error on CP-2000
IO error: Sub ITCL, lop 1, Bus TCL2, Bus thread cntRqst owerflow - ec =112
And I can`t understand the reasons for this error. I have found this error subscribe in TXV 004 50 but There is very little information about it. Could you tell me in detail about this error and what probable reasons can lead to such error?
