ASPC2 PROFIBUS Controller Statistics
The ASPC2 LAN controller maintains the following counters. They are all 1 byte long. When
these counters reach 255, they hold at 255 until cleared. For AOP, the counter name is the same
as the AOP tag name.
The ErrInvReqLen Counter
The low byte of register Local:Slot:S.Data[19], bits 0-7, counts invalid request length errors.
These errors occur when the scanner software gives the LAN controller a message that is too
long. This is an internal error and should never occur.
The ErrFifo Counter
The high byte of register Local:Slot:S.Data[19], bits 8-15, counts FIFO overflow errors. These
errors occur when the LAN controller cannot write to memory fast enough. This is an internal
error and should never occur.
The ErrRxOverun Counter
The low byte of register Local:Slot:S.Data[20], bits 0-7, counts receive overrun errors. This is an
internal error and should never occur.
The ErrDblTok Counter
The high byte of register Local:Slot:S.Data[20], bits 8-15, counts double token errors. These
errors may occur when more than one node thinks it has the token or there are wiring errors,
duplicate nodes, and so on. The scanner withdraws to the “not hold token” state (decides it
doesn't have the token) and waits until it gets the token passed to it again.
The ErrRespErr Counter
The low byte of register Local:Slot:S.Data[21], bits 0-7, counts response errors when a message
fails or there is no response from the destination. This error may be due to bad hardware or faulty
wiring.
The ErrSyniErr Counter
The high byte of register Local:Slot:S.Data[21], bits 8-15, indicates general network errors.
These errors occur when there are problems on the network, but before you get a network
timeout error.
