AB Compactlogix - what analog input/output options do we have?

Hey Joe,
Start by disabling all transactions (xxx_Transactions[x].Enabled). Next enable one transaction at a time. Keep an eye out which transaction causes the "sts_Overload" & sts_ Overlap" faults. These usually indicates that your modbus address range is incorrect. Eg: You are trying to poll 4xxx1-4xx100, however the device only allows 4xxx1-4xx50.
Good luck
