ASPC2 PROFIBUS控制器统计
ASPC2 LAN控制器维护以下计数器。它们都是1字节长。什么时候这些计数器达到255，在清除之前保持在255。对于AOP，计数器名称相同作为AOP标记名。ErrInvReqLen计数器寄存器Local：Slot:S.Data[19]的低位字节（位0-7）统计无效的请求长度错误。当扫描仪软件向LAN控制器发送的消息太长的这是一个内部错误，不应发生。ErrFifo计数器
GVC703AE01集成控制卡件寄存器Local：Slot:S.Data[19]的高位字节8-15统计FIFO溢出错误。这些当LAN控制器无法足够快地写入内存时，会发生错误。这是一个内部错误，不应发生。ERRRXOVERRUN计数器寄存器Local：Slot:S.Data[20]的低位字节，位0-7，统计接收溢出错误。这是一个内部错误，不应发生。ErrDblTok计数器寄存器Local:Slot:S.Data[20]的高位字节8-15统计双令牌错误。这些当多个节点认为自己拥有令牌或存在连接错误时，可能会发生错误，复制节点，等等。扫描仪撤回到“不持有令牌”状态（决定没有令牌），并等待直到再次将令牌传递给它。ErrRespErr计数器
寄存器Local：Slot:S.Data[21]的低位字节为0-7，用于统计消息发送时的响应错误失败或目标没有响应。此错误可能是由于硬件损坏或故障装电线。
ErrSyniErr计数器寄存器Local:Slot:S.Data[21]的高位字节8-15表示一般网络错误。这些错误发生在网络出现问题时，但在您建立网络之前超时错误。
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.
