This attribute stores the service request (SRQ) event register.
Type TSP-Link accessible
Attribute (R) Yes
Usage
requestSRQEventRegister = status.request_event
requestSRQEventRegister
Details
This attribute is used to read the service request event register, which is returned as a numeric value.
Reading this register returns a value. The binary equivalent of the value of this attribute indicates
which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the most
significant bit is bit B7. For example, if a value of 1.29000e+02 (which is 129) is read as the value of
this register, the binary equivalent is 1000 0001. This value indicates that bit B0 and bit B7 are set.
