Link Type - Check Wait Bits

Link Type:	hex 0x57, dec 87
Link Value:	Bits that must be cleared : bits that must be set

The Check Wait Bits link type can be used to check the state of the internal wait bits that are set or reset by either the Set and Reset Wait Bits Command or the Profibus DP spline processor. The link value field is split into two 8 bit fields. The high 8 bits specify the wait bits that must be cleared (0) and the lower 8 bits specify the wait bits that must be set (1). It is possible to check for some bits to be set and others cleared while still ignoring other bits all in the same link. When the wait bits match the conditions specified by the link value the step table will go to the next step specified by the Link Next field.

See the Set and Reset Wait Bits Command topic for more details.
