Static Diag
(Bit 1) Slave The Slave sets this bit to indicate the Master to be not operative because of a general
error. Typically, the DP Slave is not ready for I/O data transfer. In the case of a set static
diagnostic bit, the Master has to collect diagnostic information as long as this bit is active.
On which events or at what time this bit can be set by a Slave device, is not defined in the
norm description and can not be mentioned here.
