产品详情资料:
要设置接收的数据长度,主机写入slvRxDataLen寄存器。
这是主数据的长度,以字节为单位。该值的范围可以是
从0到244。默认长度为0。要设置传输数据长度,主机写入slvTxDataLen寄存器。
这是主数据的长度,以字节为单位。该值的范围可以是
0到244。默认长度为0。从设备最多可以向主设备返回32字节的诊断数据。这个
诊断数据作为初始启动的一部分发送到主设备。这个
诊断数据也可以在卡联机时发送,但仅当
slave请求master读取它。
诊断数据的前7个字节总是发送到主设备和组
第页,共页:
•三个站点状态字节
•参数化从属设备的主机ID
•从属标识值(两个字节)
•扩展诊断的长度
其余为扩展诊断,由用户定义。扩展的
如果扩展的诊断长度大于1,则发送诊断。
产品英文详情资料:
To set the received data length, the host writes to the slvRxDataLen register.
This is the length of the data from the master, in bytes. The value can range
from 0 to 244. The default length is 0.To set the transmit data length, the host writes to the slvTxDataLen register.
This is the length of the data to the master, in bytes. The value can range from
0 to 244. The default length is 0.The slave can return up to 32 bytes of diagnostic data to the master. The
diagnostic data is sent to the master as part of the initial startup. The
diagnostic data can also be sent when the card is online, but only when the
slave requests that the master read it.
The first 7 bytes of diagnostic data are always sent to the master and consist
of:
• the three station status bytes
• the ID of the master that parameterized the slave
• the slave Ident value (two bytes)
• length of extended diagnostics
The remainder is extended diagnostics and is user-defined. The extended
diagnostics are sent if the extended diagnostic length is greater than 1.
